Geary BRT Study Regional Travel Demand ModelingThe San Francisco Travel Demand Forecasting Model (SF CHAMP) provides data on many aspects of thebase year and projected future year conditions along the Geary Blvd corridor. This memorandum documentsthe methodology and results of the modeling work done for the base and future scenarios for the Geary BusRapid Transit Feasibility Study.
In this document, the assumptions used for the Model will be discussed, including land use and network
inputs in section 2. The 2005 base model validation is presented in section 3, and the base model outputs areshown in section 4. Section 5 documents the No Project results as compared to the base, while section 6analyzes the Geary project alternatives, as compared to the No Project.
1.BACKGROUNDSF-CHAMP is the Authoritys regional travel forecasting model, which is used for a wide array of planningstudies and project evaluations. CHAMP was originally developed in the year 2000, so most of its inputswere originally based on data available at that time. This included 1990 Census data, and transit and roadcounts from the late 1990s. Travel patterns in the city have changed since then, due to the 2001 recessionand the current slow recovery. The original year 2000 model did not reflect these changes.
Since this BRT study explored short-term alternatives, it was important that CHAMP accurately reflect the
existing conditions so that future estimates could be compared realistically. In order to do this, the Authoritydeveloped an updated 2005 base year model with incremental changes to the core model inputs. Thedevelopment of the 2005 base year is described below in section 2, and the analysis of the year 2015alternatives is documented in sections 3 through 6.
The main goals of this modeling effort were: (1) to estimate future transit ridership along Geary Boulevard inseveral alternative configurations; (2) to examine the effects of taking one lane from auto traffic in eachdirection along Geary; and (3) to provide inputs for subsequent analysis steps which will further examine thedetailed operations of transit and autos on Geary.
2.INPUTS AND ASSUMPTIONSSeveral inputs to the model were modified for the new base year: land use data, regional travel demand,roadway characteristics, and transit network representations.
2.1.Land Use InputsThe San Francisco Planning Department develops land use forecasts in five-year increments through year2025, based on countywide totals provided by Association of Bay Area Governments (ABAG). Table 1 belowsummarizes the overall amount of employment, households, and employed residents inside the city of SanFrancisco. This land use data is a key zonal-level input for the CHAMP model. Planning DepartmentScenario B was used for all Geary model analysis.

2.2.Regional TravelCHAMP directly predicts travel for San Francisco residents only. It always uses the MetropolitanTransportation Commission (MTC) Model for estimating regional travel demand, and only 2000 and 2025MTC forecasts are available. Regional demand estimates for 2005 and 2015 had to be created. There are twomethods for doing this: either by running the MTC Model using ABAG 2005 and 2015 inputs, or by creating"fratared" (factored) trip tables that target future totals but mimic the regional trip distribution from year2000.
Rerunning the MTC model has one advantage: it makes the regional results sensitive to changes in ournetwork. However, the factoring process has several advantages: it uses the known-good 2000 MTC results asa starting point; it avoids the pitfalls of having to examine the adjustments hardwired into the base MTCmodel to make sure the final numbers are reasonable; and it is much easier and less time-consuming to factorthe trip tables than to run the MTC model.
Given the uncertainty and time-consuming nature of creating a new forecast year for the MTC model, theknown-good regional demand for year 2000 was fratared to match the new targets for 2005 and 2015tripmaking.
Work trips use employed residents as the control total on the production end, and employment on theattraction end. Nonwork trips use various combinations of households, employed residents, and jobs ascontrol totals. Table 2 below summarizes the regional trip ends created and used for this study.

2.3.Roadway Network ModificationsThe primary change to the San Francisco highway network assumptions between the 2005 Base and the 2015No Project was the Inner Geary lane reduction project. Because the roadway counts along Geary were takenin 2004, we assumed that the base model did not include the roadway effects of the Inner Geary project. Allfuture horizon years assumed that one lane was removed in each direction on both Geary Street and OFarrellStreet east of Van Ness Ave.
Octavia Boulevard and the Central Freeway off-ramp were modeled as open for all of the Geary model runs.
A ground truthing initiative verified that the roadway characteristics in the model were representedaccurately. This verification included number of lanes, turn restrictions, and peak-hour tow-away laneconversion for all east/west roads in the corridor from Turk/Balboa Street to California Street, and formajor north/south roadways as well.
Many changes exist in the regional roadway network in the 2025 road network from MTC. The timing ofthese improvements is unknown, so none were included in the 2015 analysis. Since these road improvementsare outside the city, it is unlikely they impact the Geary corridor.

2.4.Transit Network ModificationsThe current travel times and headways in the model were compared against Fall 2005 Muni operating data forlines in the study area, to make certain that service was correctly reflected. Also, some network changes werecoded that mirror Muni service changes since 2000. Future transit networks include improvements that arealready programmed. Table 4 below lists the transit network assumptions for the forecast years. Changes inearly years propagate to all future networks unless otherwise noted.
All of the Geary roadway counts were collected in the year 2004, and therefore the base year highwaynetwork is based on the year 2004 such that it does not include the recent Inner Geary lane narrowingproject. However, the transit network used in the model calibration is based on the transit networks providedin the September 2005 schedule following the most recent round of Muni service cuts. The decision wasmade to use 2005 transit networks with a 2004 roadway network so that the 2004 counts could be used tocalibrate the road network, while the recent service cuts would not obscure the Geary transit ridership results.

3.VALIDATIONTwo data sources were used to calibrate and validate the SF-CHAMP travel demand model for the GearyBRT project. First, roadway volume estimates were compared with the observed current roadway volumes.Secondly, transit ridership estimates were compared to the observed transit ridership provided by Muni.
Lastly, a model development effort was undertaken to improve the Models roadway assignment method inthe Geary neighborhoods. The research focused on increasing the roadway assignment accuracy on local andcollector streets throughout the City. The details of this assignment improvement project are presented inthe last part of this section.
3.1.Observed Roadway VolumesObserved traffic turning movement counts were collected by the Project Consultant at selected intersectionswest of Van Ness Ave on Geary Blvd in December 2004. The comparison of these traffic counts show that
the results along Geary Blvd are well within acceptable range. There are some discrepancies, mostly in thereverse PM peak direction where the model returns higher roadway volumes than observed in the project areawest of Arguello Avenue. The Model consistently returns high volumes in the Westbound direction atLaguna Street, while most other locations are within 20%. Link-level volumes within 20% are generallyconsidered adequate for modeling purposes.
The following figures display the comparison of model and count volumes in the eastbound and westbounddirections. The Model volumes are compared against both the original Synchro counts provided by MTAand observed manual counts collected by the Project Consultant. The conclusion is that the SF Model is areasonable (and conservative) estimator of current traffic volumes and should be a reliable estimator of futurevolumes as well.

To support traffic operations, a Synchro model was subsequently developed and calibrated to the observeddata described above. However, observed data for the entire length of Geary Blvd was not available for usein the Synchro model. The following adjustment was applied to smooth the historical counts that were usedto populate the Synchro model where recent counts were not available: since the observed manual countscollected for the Geary Blvd BRT project closely matched the existing Synchro counts provided by MTA, theexisting Synchro count data was used to calibrate the model for the intersections in which we did not haveDecember 2004 counts.At Collins St, just west of Masonic Blvd, automated counts were taken at several locations across a screenline
stretching from Turk St to California St. This location was used to verify the accuracy of highway volumes ofthe parallel roadways at a single point along Geary corridor. As a result, roadway facility types were adjustedup or down in order to provide the correct proportion of traffic along each parallel street in the corridor. Theresults of this comparison can be seen in Figure x.
3.2.Observed Transit RidershipTransit count data collected by the Project Consultant and Muni observers were used to validate the transitridership numbers generated by the SF-CHAMP model.
Muni Boardings on the 38 and 38L L ines
The Muni 38 and 38L share the same route along Geary Blvd in the study area from the Transbay Terminal
to 33rd
Avenue, however the 38 Limited makes many fewer stops and consequently has a shorter travel time.West of 33rd Avenue, the routes diverge with the limited service continuing along Geary Blvd to Point Lobos,and the local service splitting into two routes. The first local route turns south along Balboa Street destinedfor Ocean Beach, while the second local route turns north to the VA hospital at Fort Miley. The headwayson the two local routes are identical.
As can be seen in the figures below, the general shape of the transit volumes in the Model versus theobserved counts matches fairly well. The model does underestimate transit volume in the eastbounddirection while overestimating westbound transit during the PM peak. This is true for both the local andlimited services.
The recalibration of the Models highway assignments (See section 3.3) shifted additional riders onto transit,thus leading to an overestimate of approximately 20% for all systemwide Muni transit boardings. Until theupcoming CHAMP 3 mode choice model recalibration later this summer, line-level transit volumes will pivotoff of ridership figures as reported in the latest Muni Short-Range Transit Plan (SRTP).

3.3.Roadway Validation EnhancementsExamination of roadway volumes revealed that the model consistently produced lower volumes on localstreets than were observed in the base conditions. This appeared to be true across the entire city network.When we removed a lane from Geary for tests of the with-project alternatives, there were noticeablediversions to the smaller parallel streets, since the model saw excess capacity there.
The original model development documents showed that, consistent with FHWA guidelines, higher-facilitytype roadways were validated to a greater degree of accuracy. This may be appropriate for suburban settings,
but for San Francisco with its dense grid system and very few freeways, accurate volumes on arterials,collectors, and local streets are at least as important as freeway volumes. This section documents the researchefforts to get base volumes on local streets closer to the observed volumes. Achieving this goal would alsohave the effect of reducing the erroneous diversions to local streets in the build alternatives. For a fulldescription of the road validation exercise, contact the Authority for a copy of the roadway validation memo.
Methodology
The standard roadway validation technique is modification of the alpha and beta values in what is known asthe BPR equation shown below. We chose to modify the alpha, beta, and freeflow speed/capacity tables,which allowed us to match volumes and the observed CMP speeds more closely, while retaining the correctform of the BPR equation.

Vtt 0.1*0
The standard BPR equation for calculating congested roadway travel time.
Dozens of combinations of speed, capacity, and alpha/beta values were tested in order to match roadvolumes by facility type, area type, and screenline values. The existing models speed and capacity tables didnot match MTCs latest model, so as a first step we tried matching MTCs inputs. The results of this test wereworse the original model validation, particularly with respect to speeds being far too high, especiallycompared to observed CMP speeds.
Since neither the original model nor the MTC model speed/capacity tables resulted in good validation on
smaller streets, we attemped many additional combinations of inputs to the assignment process. We testedupwards of fifteen different variations of the speed and capacity tables, as we tried to converge on a set ofstarting conditions that resulted in accurate speeds and volumes across all facility types and in all time periods.
Validation Results
The tests converged on a solution which included modifications to the speed/capacity tables and the BPRequation coefficients. For speeds, we found that less gradient in the freeflow speeds between high- and low-facility types worked best; i.e. the freeways and arterials had lower initial freeflow speeds while the smallerstreets had higher initial speeds. For capacities, lower capacities on the small streets allowed the observed(existing) levels of traffic to remain without additional room for growth, which expert planners believed wasgenerally not present. The BPR curve modifications were designed to encourage traffic to remain on arterialsas much as possible.
Table 3.2 below shows the final speed/capacity tables used in the validation.

The new speed/capacity tables and BPR equation coefficients resulted in a closer match of estimated volumesto existing ground counts. Table 3.3 below shows the aggregate results of the final validation. In aggregate,volumes on all facility types except freeways matched closer to existing counts; freeways were originallyalmost 9% overutilized, while this final validation shows them -11% underutilized. Arterials are now quiteclose to observed, while collectors and local streets are less underutilized than before.

Freeway Major Arterial Minor Arterial Collector Local Street Total
Relative Error: -11.3% +2.4% -1.4% -14.6% -28.1% -4.7%
P.M. Peak and Midday Time Periods
The P.M. period validates even better than the daily average. Overall aggregate volumes are within 2%, andby facility type, all match within ten or even five percent, except for local streets which are within 25%.Estimated volumes in the midday period are consistently lower than observed volumes, on average about10%.
Screenlines and Bridges
Bridge volumes were not particularly affected by this revalidation. In the P.M. period, estimated movementsin both directions on the Golden Gate and Bay Bridges match observed volumes within about five percent.Estimated volumes at the San Mateo county line are almost precisely correct in the P.M. period, (less than
0.1% difference in volume), although estimates for individual facilities at the county line differ: I-280, forexample, is about 9% high northbound and 13% low southbound.
Diversions onto Local Streets
The revised BPR curves and capacity tables had the intended effect on local street volumes. The model nowmatches observed volumes on small streets more closely, although it still underestimates those volumes byabout 30%. Since those streets were very underutilized in the original model, they filled up with new trafficin the future alternatives.

With this new road validation, the model does not fill the local streets with additional traffic that in realityprobably will not use those facilities; they are small, frequently have numerous stop signs, and dont have theexcess capacity that the model originally estimated especially since the model was underestimating base-yeartraffic conditions on these streets. Thus, estimated diversions onto local streets still happen but to a muchlesser degree than in the original model. This is exactly in line with our planners judgment about how thesestreets will behave in the future.
Validation Summary
This research successfully validated the SF-CHAMP road assignments to observed volumes on all streettypes, large and small, simultaneously. An added benefit of the revalidation is that the model now reacts tocapacity changes (such as lane reductions) more rationally.
Making these modifications to the core of the model had some consequences which shouldnt be surprising:(1) mode choice is directly affected by changes in travel time, so the new lower roadway speeds resulted inhigher transit mode share; (2) the assignment procedure now takes about 50% longer to converge than in theoriginal form, due to more balancing among parallel streets of varying facility types.
For this study of the Geary corridor, traffic diversions are a critical component of the analysis. Since thetransit growth of the build alternatives is going to be compared on a relative scale (instead of absolutevolumes), the boost in transit ridership will be mostly cancelled out since it will exist in all base and futurescenarios. Therefore, we are comfortable using this technique. The full SF-CHAMP model will be
recalibrated this fall, to incorporate the findings of this roadway research while matching existing transitboardings more accurately.
4. 2005 BASE YEAR MODELING RESULTSCHAMP produces trip tables of travel demand for all origin/destination pairs in the region. These tables aresummarized into district-level tables, and then compared to identify trends in mode share or trip growth. Inaddition, trip tables are assigned to the roadway and transit systems, creating link-level volumes and route-level ridership. The results of these analyses are described below. For the sake of brevity, P.M. peak periodresults (3:30 pm to 6:30 pm) are highlighted in most cases.
4.1.Screenline AnalysisA screenline is used to measure traffic volumes across a specific set of roadways. For this analysis, the Gearycorridor is defined as more than just Geary Blvd itself, since several of the roads parallel to Geary Blvd areinterdependent; they work together and affect each other. Instead, traffic volumes along the east-westroadways in the vicinity are summed together. The Geary corridor includes Geary Blvd, Balboa and AnzaStreets to the south, and Clement and California Street to the north. The total volume of traffic on all fiveroads is measured at a specific cross street. This traffic measure is called a screenline.
It is important to note that screenline analysis only reports motorized trip volumes (auto and transitpersontrips). Unmotorized persontrips using the walk or bike modes are not reflected in the totalpersontrips. In other words, the mode share figures reported are the share of total motorized persontrips,not the share of all persontrips. This result reflects a limitation of the Model in not being able to assignpedestrian and bike volumes to the roadway network.
Eight cross streets define the screenlines used in this study. They are Van Ness, Webster, Divisadero, Collins,Arguello, Park Presidio, 25th Ave, and 33rd Ave. See Figure 4.1 for the geographic location of the eightscreenlines.
In the following analysis, the volume of person trips by auto and by transit is reported at various screenlinesalong the Geary corridor as well as on Geary itself.

4.2.Zone Based AnalysisA zone-based analysis reveals the trip patterns and characteristics of all the trips coming from and going tothe blocks and zones that neighbor Geary Blvd. This provides a slightly different picture of tripmaking thanthe patterns and characteristics of trips operating on the Geary corridor at a particular screenline.
For the zone-based analysis, the City was divided into 14 zones. The Geary corridor itself was segmentedinto four districts, including the Outer Richmond, Inner Richmond, Western Addition/Japantown, and theTenderloin. The Outer Richmond was defined as the area north of Golden Gate Park, south of the Presidio,and west of Park Presidio. The Inner Richmond was defined as the area north of Golden Gate Park, southof the Presidio, east of Park Presidio, and west of Baker. The Japantown/Western Addition was defined as
the area north of Fulton, south of California, east of Baker, and west of Van Ness. The Tenderloin wasdefined as the area north of Turk, south of Pine, east of Van Ness, and west of Powell.
Mode Shares
Table 4.3 below shows the mode split of all daily trips with one end Geary corridor, 2005. Local trips haveone end in a Geary corridor neighborhood, and one end in San Francisco; regional trips have one end in aGeary corridor neighborhood and one end outside of San Francisco.

Most trips to or from the Geary corridor neighborhoods and other parts of San Francisco occur by car,followed closely by walk/bike trips. Transit trips to and from Geary and other parts of San Francisco arerelatively low less than 15%. Regional trips to and from the corridor are mostly made by car, although thePM regional transit share is almost 25% reflecting the high regional BART use in the Tenderloinneighborhood.
Origins and Destinations of Trips to/from the Geary Corridor
The following discussion of the origins and destinations of trips with one leg in a Geary corridorneighborhood refers to Table 4.4. 27.8% of trips in the Project Area have both their origin and destination inthe Geary Corridor. 61.3% of Geary trips are to other locations within the City, while 10.9% are to regionaldestinations.
% of Destinations Destination
27.8% Project Area
61.3% Local - out of Project Area
10.9% Regional - out of SF
Trips that begin on the Geary corridor and end in the East Bay have the highest mode share (43%) due toBART accessibility. The highest transit shares reflect employment availability and transit accessibility - tripsfrom Geary to the East Bay and downtown, as one might expect, have relatively high transit shares.

4.3.Summary Transit has an estimated 6 to 10% mode share among trips to and from the neighborhoods along the
Geary corridor.
Transit mode share in the corridor is estimated to be highest among those traveling to downtownlocations (20%) and to the East Bay (43%).
Intradistrict trips and trips to adjacent neighborhoods have lower transit shares due to higher walk andbike accessibility.
Almost one in four trips in the Geary corridor are destined to locations along the Geary corridor. Only10% of trips in the corridor have destinations outside of San Francisco.

5.2015 NO PROJECT FORECASTTo help understand the effects of future changes in land use, demographics, and growth that are not directlyrelated to the project, a 2015 No Project alternative was studied. This alternative included 2015 householdand employment forecasts, and in-progress or planned updates to the road and transit networks as describedin Section 2. The results of this alternative will be compared to the build project alternatives in order tomore easily distinguish between changes due to the project and changes due to background growth and
development.Growth factors for roadway movements informed the subsequent Synchro traffic modeling steps. Bothnorth/south and east/west roadway growth factors were developed.
5.1.East-West Roadway Growth Factors: 2005 to 2015Projected P.M. peak hour traffic growth in the corridor is between 1.02 and 1.11, with more growth in theoff-peak direction (eastbound) than the reverse direction. This higher growth is consistent with the higherthan expected eastbound volumes also observed during the model validation.
Tables 5.1 and 5.2 show the East/West growth factors for the 2005 to 2015 No Project alternative. The studyarea was divided into eight sections along the screenline boundaries. While in the No Project the factors arevery similar, the future alternatives show more differences on the two portions. A 10% decrease in traffic
volume is estimated east of the Van Ness screenline due to the Inner Geary narrowing, which was notmodeled in the 2005 roadway base.

5.2. North-South Roadway Growth FactorsThe cross streets which intersect with the Geary corridor also exhibit changes in volume between 2005 and
2015. The direction and magnitude of these changes depend on the type of street and how close that street isto the downtown urban core. Model volumes for the 2005 and 2015 No Project are presented in AppendixA. Many of the minor streets were bundled together to smooth the growth factors with adjacent similarcross-streets. Major arterials such as Park Presidio or Masonic were left separate.
5.3.Persontrips Screenline AnalysisThe following Tables 5.3 and 5.4 report the growth in motorized persontrips (auto and transit) for the GearyCorridor screenline as well as Geary itself. Growth in non-motorized trips (walk and bike trips) is notreflected in the figures.

5.4.Zone Based AnalysisThe citywide transit mode share is not projected to change much between 2005 and 2015 No Project,hovering around 20 percent. Trips to and from the Geary corridor have a higher percent transit than citywidetrips, but trips that both begin and end along Geary actually have a much lower transit share. The low transitmode share for intracorridor trips is due to a high percentage of non-motorized trips (particularly walk trips).Walking is quite competitive with transit in the corridor, due to the high walkability of the area and therelatively slow transit speed in the No Project alternative.

Mode Share
Auto mode share is quite consistent between 2005 and 2015, changing not at all in the P.M. period (61%) anddropping in the midday (61% to 54%). The model also shows a clear competition between walk/bike modesand transit. Transit mode share is estimated to drop slightly between 2005 and 2015, while the walk/bikemode share increases. This trade-off has been exhibited in the SF-CHAMP model on other projects as well,and may be due to changes in the distribution of future development along the corridor more than actualdifferences in transit service or congestion levels.
5.6.Summary Between now and 2015, auto traffic in the corridor is expected to grow at about 5% at most screenline
locations along the Geary corridor Park Presidio Blvd. is the fastest growing location with an estimatedgrowth of 10%. While the model shows various growth rates at different points along the corridor,including some slight traffic decreases at the Van Ness Ave. screenline, the overall growth rate isconsistent with the modest changes expected in the areas surrounding the corridor.
The Inner Geary narrowing project is expected to drive down auto traffic east of the Van Ness Avescreenline by up to 25%. This is expected, due to the decreased capacity of this arterial through the heartof downtown.
Transit mode share is not expected to change significantly in the future no-project scenario; a slight
decrease in transit share is possible due to increased competition with the walk mode. Auto mode sharein the corridor is also estimated to remain about the same.
6.2015 WITH PROJECT FORECASTSThis section describes the initial model results for the 2015 project alternatives. Four build alternatives wereanalyzed: a side-running alternative and three center-running configurations. For modeling purposes, thefour alternatives had identical stop locations, but different travel time savings and headways (with the centeralternatives being faster). The SF-CHAMP model outputs will be analyzed using Synchro and VISSIM in thenext stage of the study.
6.1.Network Changes in Project AlternativesThe BRT system is given one lane of exclusive right-of-way in each direction along Geary Blvd, betweenGough Street and 33rd Avenue. Since Geary Blvd is currently three lanes in each direction, this equates to a33% decrease in available right-of-way for other vehicular traffic.
Left turn restrictions are added along Geary to prevent unprotected turns across the BRT right-of-way. Noleft turns are permitted except at protected, signalized intersections. These signals are at:
Eastbound: Fillmore, Presidio, Masonic, Spruce, Palm, 4th, 8th, 12th, 15th, 19th, 23rd, 27th, 31st, 35thWestbound: Webster, Fillmore, Presidio, Masonic, Blake, Stanyan, 3rd, 7th, 11th, 15th, 18th, 22nd, 26th, 30th, 34th
Compared to the current configuration of the corridor, this means that 11 more eastbound and 12 morewestbound left turn locations are prohibited in the project alternative. Turns are either prohibited due to lowturning volumes or to prevent adverse pedestrian conditions.

6.2.East/West Auto Traffic FactorsThe main purpose of this comparison is to advise the Project Consultant on factors to use when building the2015 BRT Synchro models. These factors will be used by the Project Consultant to adjust the 2015 NoProject traffic model for both the side and center build alternatives. Factors are given for Geary Blvd
specifically and for the corridor as a whole. Table x, below, summarizes the roadway factors for Geary andthe parallel streets in the corridor for side and center alternatives. For the sake of brevity, only one of theCenter alternatives is presented. The roadway factors among the various Center alternatives are notsignificantly different to warrant individual discussion.
Geary Blvd
Westbound PM Roadway volumes drop along Geary up to 38% (a factor of 0.62) at Webster, with mostscreenline locations dropping around 25%. This means, in essence, that 75 percent of the traffic previouslyon Geary now uses a facility which has 66 percent of its original capacity. The screenline at Webster losesmore traffic since this roadway segment
Parallel Streets
When traffic is examined across the entire corridor (which includes California, Clement/Euclid, Geary,Anza/OFarrell, Balboa/Turk, and all streets in between; see Figure x above), roadway volumes on theparallel streets rise somewhat in most locations. This reflects that in the build alternatives, a portion ofexisting traffic diverts from Geary Blvd onto the parallel streets.
Both the side and center alternatives show slight decreases in traffic volumes along the corridor at thescreenline level, up to 8% in the Richmond neighborhood to less than 2% near Van Ness Avenue.Significant differences in roadway capacity were not observed between the Side and Center alternatives.

6.5.Transit RidershipThe improved transit travel times of the side and center alternatives result in increased transit boardings andmode share. Compared to the 2015 No-Project, daily boardings on the Geary routes increase 16.8% for theside alternative and up to 24.7% for the center alternatives. Of the Center alternatives, Center A has thehighest growth in ridership while the skip stop alternative (Center C) has the lowest growth. In fact the skipstop alternative ridership numbers are lower than the side alternative. Table 6.8 summarizes daily boardingsby alternative, below.

Ridership on the 38L-Limited, representing the new BRT service, increases the most almost doubling insome scenarios while the slower local ridership decreases by 25 to 40%. The 38L-Limited ridershipincreases significantly because of the faster travel times, in combination with more frequent headways andexpanded hours.
The new BRT riders come from a variety of sources. The model predicts that the new BRT service will attractbetween 2,000 and 3,500 new transit riders every weekday, as well as attracting significant numbers of existing
Muni riders who shift from parallel routes, as well as from express and local Geary routes. This is becausethose existing riders are willing to walk farther to receive the benefit of shorter travel times and more reliable
service. 2 The Center A alternative attracts the most new riders (3,400) while the Center B alternative attractsthe fewest (2,250).
Other BRT implementations in the U.S. have found that up to one quarter of BRT users are new transitriders who did not take transit before BRT was implemented. This suggests that the SF-CHAMP model maybe under-predicting the propensity of auto users to switch to BRT and therefore is a conservative estimate.
As shown in the table below, transit mode share to and from the Geary corridor also improves. PM peakhour transit mode share increases from 15.6% to 15.7% in the side alternative and also to 15.7% in the centeralternative.

1 The no-project ridership was calculated by multiplying the FY2004 average daily ridership reported in Munis ShortRange Transportation Plan (SRTP) by the percent change predicted with the travel forecasting model.
2 The Federal Transit Administrations funding criteria now focus on this notion of user benefit instead of newtransit riders. FTA recognizes that benefits which accrue to existing transit riders and to new riders are both consideredproject benefits.

6.6.Maximum Load Point (MLP) AnalysisThe CHAMP model was used to perform an analysis of crowding at the Maximum Load Point (MLP) alongthe Geary corridor. The MLP is the point on the transit route where the load is highest. In most timeperiods for both the 38 Local and Limited, the MLP was found between Laguna and Van Ness.
Muni considers a transit route to be overcrowded if the transit load at the MLP is greater than 85% of thevehicles capacity. Muni operates 60 ft articulated buses on the 38 Geary route. A 60 ft articulated bus has acarrying capacity of 94 persons. The 85% crowding standard for this type of vehicle is 80 persons. None of
the BRT alternatives exhibit crowding at the MLP. The highest forecasted load is 69, which is found for theCenter B alternative in the inbound direction for the 38L.
The highest forecasted load for the BRT alternatives is 45% higher than the corresponding load in the 2005base. Anecdotal evidence suggests that riders consider the 38L route to be crowded due to bus bunching andcongestion while boarding the front of the vehicle. Proof-of-payment (POP) is expected to be used on theGeary BRT route, thus allowing boardings from all doors and reducing crowding at the front of the vehicle.However, it will also be necessary to ensure that Muni line management is disciplined enough to provide aconsistent headway between buses during the peak hours to avoid crowding created by bus bunching.

6.7.Accessibility AnalysisThe SF-CHAMP model can estimate the accessibility of jobs for residents along the Geary corridor. For thepurposes of this analysis, four representative locations were chosen: downtown (Market/Montgomery),Japantown Center, Divisadero St at Geary Blvd, and 20th Avenue at Geary Blvd. The largest changes in totaljob accessibility by transit occur at Divisadero/Geary (+72%) and 20th Avenue/Geary (+27%), while losses in

6.8.Equity AnalysisAn equity analysis was conducted to compare the benefits of a Geary BRT project to different groups ofpeople. The proportion of project benefits to low-income households was analyzed, as well as the proportionof project benefits to zero-car households relative to households with access to a vehicle.
According to model outputs, residents of zero-car households would save an average of 0.03 minutes per trip
in the Side BRT scenario and 0.07 0.13 minutes per trip in the Center BRT scenarios. By contrast,members of households with access to a vehicle would save an average of 0.13 minutes per trip in the SideBRT scenario and 0.27 0.40 minutes per trip in the Center BRT scenarios, as shown in Table 6.13.
Furthermore, residents of low-income households would save an average of 0.01 minutes per trip in the SideBRT scenario and 0.05 0.09 minutes per trip in the Center BRT scenarios. Residents of households that arenot low-income would save an average of 0.15 minutes per trip in the Side BRT scenario and 0.29 0.44minutes per trip in the Center BRT scenario.
These results are due to the fact that members of low-income and zero-car households are more likely to takeshorter trips.
The Side BRT scenario provides most of its benefits to households that are not low-income and do haveaccess to a vehicle. As seen in Table 6.14, in the Side BRT scenario, 16% of all minutes saved from the
project would be saved by zero-car households, although they represent 27% of all San Francisco households.In addition, 4% of total minutes saved in the Side BRT scenario would go to low-income households,although these households represent 15% of San Francisco households.
The Center BRT scenarios provide a more equitable distribution of benefits. In the Center A scenario, 29%of minutes saved go to zero-car households, and 23% of minutes saved go to low-income households. In theCenter B scenario, 20% of minutes saved go to zero-car households, and 14% of minutes saved go to low-income households. In the Center C scenario, 25% of minutes saved go to zero-car households, and 17% ofminutes saved go to low-income households.

6.9.Diversions AnalysisA physical reduction in auto capacity along Geary Blvd is an end result of all Project alternatives for theGeary BRT Study. A need to divert trips from Geary will emerge as dedicated bus lanes are added whilemaintaining as many on-street parking spaces as is possible. Geary Blvd carries a large amount of the trafficdestined for the northwestern neighborhoods of the City, particularly the Richmond District. The purpose ofthis analysis is to determine the number of trips that will likely be diverted to parallel streets or alternatecorridors.Methodology
The SF-CHAMP travel demand forecasting model can take a snapshot of the trips crossing a specificintersection (screenline) at a particular time period, and produce a report of various attributes of those trips.
This analysis looks at the origins and destinations of all modeled vehicles at a specific Geary screenline duringthe PM peak. This feature, known as "select-link analysis," is useful for analyzing the travel patterns of theusers of a facility. Here, the actual origins and destinations of vehicles using Geary can be summarized todetermine how many of the trips using Geary have a destination on the corridor, versus how many trips arejust passing through.
For this analysis, the selected link is Geary Blvd at Divisadero Street. This section of Geary was chosenbecause it was far enough west to be close to the main project impacts (Masonic and Fillmore), while it wasfar enough east to still be representative of most of the traffic along Geary. The highest traffic volumes alongGeary Blvd occur between Laguna and Masonic.

As reported in Section 6.2, when one lane of mixed traffic is removed in each direction from Geary, roadwayvolumes drop on Geary an average of 30%. This indicates that 70% of pre-project Geary traffic continues touse a facility that now has 67% of its former mixed traffic capacity.
The trips that divert off of Geary Blvd as a result of the project primarily divert to other streets in the Gearycorridor, as well as other corridors entirely, making use of San Franciscos grid system, as shown in Table6.13. See Figure 6.1 for a visual depiction of the diversions that result from the Geary project. This estimateof diversions activity is reasonable based on the current origin-destination patterns of trips using the Gearycorridor currently.
Figure 6.1. Trips Diverted from Geary Blvd, With-Project.
With the proposed conversion of a general purpose travel lanes (in each direction) to dedicated transit lanes,67% of mixed traffic capacity is retained. The SF Model suggests that 70% of the existing auto traffic willremain on Geary Blvd even after capacity reduction. This means that the model is projecting a diversion of30% of traffic off of Geary. SF-CHAMP shows that over 60% of the traffic might be diverted out of thecorridor altogether and almost 10% of auto trips may not occur at all.
West of Park Presidio, there are no significant traffic diversions since the BRT lanes can be accommodatedwithout converting regular traffic lanes. Some minor variations in traffic patterns are expected on individualstreets due to the likely need for some left-turn restrictions along Geary.
In summary, the amount of diversion is less than proportional to the amount of capacity removed, because:
Some drivers will switch to transit and walking;
Those who continue to drive may change the time of their trip to avoid peak hours;
Drivers avoid slow local streets with lots of stop signs; and
Geary will continue to be an attractive route for many drivers because the street will be optimized fortraffic flow and buses will be in a separate lane, out of the way of cars, though some drivers will optfor other parallel arterials.

6.10.Conclusions Roadway volumes drop along Geary an average of 30 percent (a factor of0.70). This means, in essence,
that 70 percent of the traffic previously on Geary now uses a facility which has 67 percent of its originalcapacity.
In both the side and center With Project alternatives, the absolute number of transit boardings and thetransit mode share both increase, on Geary itself and in the corridor.
The trips that divert off of Geary Blvd as a result of the project divert to other parallel streets in theGeary corridor, as well as other San Francisco corridors entirely.
