Congestion According to County and residents’ input, there are three potential shortcut routes that a.m. peak period commuters are currently using to bypass typical congested conditions on the U.S. 101 Southbound freeway. They are as follows: Route 1 (R1): Use 101 Southbound off-ramp to Miller Creek Road, then pass straight through the ramp intersection to return to the freeway via the Miller Creek Road on- ramp Route 2 (R2): Use 101 Southbound off-ramp to Miller Creek Road, turn right onto Miller Creek Road, make a U-turn at the Marinwood Avenue intersection, then return to the freeway via the Miller Creek Road on-ramp Route 3 (R3): Use 101 Southbound off-ramp to Miller Creek Road, turn right onto Miller Creek Road, turn left onto Las Gallinas Avenue, turn left onto Lucas Valley Road, then return to the freeway via the Lucas Valley Road on-ramp The above three cut-through routes are illustrated in Figure 1. It should be noted that in each case, motorists are utilizing a continuous auxiliary lane on the southbound freeway between the upstream Alameda Del Prado on-ramp and Miller Creek Road off-ramp.

February 8, 2008 Mr. Amanuel Haile Project Manager Marin County Department of Public Works P.O. Box 4186 San Rafael, CA 94913-4186 Subject: Final Draft Report: Miller Creek Road Interchange Traffic Calming Study

(Project No. 036-038) Dear Mr. Haile: The purpose of this letter report is to provide a summary of results for the subject study. For several years, Marinwood residents have expressed concerns that southbound commuters on nearby U.S. 101 are using the southbound off-ramp at Miller Creek Road to bypass the freeway congestion during a.m. peak commute hours. Several attempts have already been made in the past to either eliminate or reduce cut-through traffic at this location. Under Marin County direction, TJKM has collected extensive travel time and volume data in the field to estimate the extent of the cut-through issue. The focus of our study has been to develop effective solutions to keep commute traffic on the U.S. 101 freeway and prevent the bypass of freeway congestion via local county roads. TJKM has developed several preliminary recommended alternatives with the goal of reducing or eliminating cut-through commute traffic. The preliminary alternatives described in this letter report are meant to guide the ongoing public input process and to help build consensus on a traffic calming solution for the Marinwood area acceptable to residents, the County, and Caltrans. Shortcut Routes to Bypass U.S. 101 Southbound A.M. Congestion According to County and residents’ input, there are three potential shortcut routes that a.m. peak period commuters are currently using to bypass typical congested conditions on the U.S. 101 Southbound freeway. They are as follows:

• Route 1 (R1): Use 101 Southbound off-ramp to Miller Creek Road, then pass straight through the ramp intersection to return to the freeway via the Miller Creek Road on-ramp

• Route 2 (R2): Use 101 Southbound off-ramp to Miller Creek Road, turn right onto Miller Creek Road, make a U-turn at the Marinwood Avenue intersection, then return to the freeway via the Miller Creek Road on-ramp

• Route 3 (R3): Use 101 Southbound off-ramp to Miller Creek Road, turn right onto Miller Creek Road, turn left onto Las Gallinas Avenue, turn left onto Lucas Valley Road, then return to the freeway via the Lucas Valley Road on-ramp

The above three cut-through routes are illustrated in Figure 1. It should be noted that in each case, motorists are utilizing a continuous auxiliary lane on the southbound freeway between the upstream Alameda Del Prado on-ramp and Miller Creek Road off-ramp.

Existing Traffic Volumes TJKM additionally collected two types of existing traffic volumes in the study area, shown in Figure 1 and discussed below. Attachment A includes all 48-hour count sheets for the study segments. Attachment B includes all a.m. peak hour count sheets for the study intersections.

48-Hour Counts

TJKM collected continuous 48-hour two-way traffic counts in September 2007 along the following three roadway segments:

1. Miller Creek Road between Marinwood Avenue and Las Gallinas Avenue

2. Las Gallinas Avenue between Roundtree Boulevard and Elvia Court

3. Lucas Valley Road between Las Gallinas Avenue and Los Gamos Road It is notable that on all three segments, the 24-hour volumes on the individual two days are heavier in the direction of the potential cut-through Route 3 than in the other direction. That is, westbound Miller Creek Road, southbound Las Gallinas Avenue, and eastbound Lucas Valley Road have higher 24-hour volumes than in the corresponding opposite direction for each roadway. Under typical conditions, a roadway often has heavier volumes in one direction during a typical weekday a.m. peak period, and then heavier volumes in the opposite direction during a typical weekday p.m. peak period. As a result, volumes in both directions of the roadway should be approximately balanced. However, since the three study roadway segments do not have balanced directional volumes over either 24-hour period, this suggests a commute pattern in which vehicles are not returning in the opposite direction along the same path. This suggests that commuters consider cut-through Route 3 a viable route during the a.m. peak period, but instead of using the reverse route during the p.m. peak period, they would instead travel along U.S. 101 Northbound.

A.M. Peak Hour Intersection Counts

TJKM collected existing turning movement counts between 7:00 and 9:00 a.m. within the above mentioned same 48-hour observation period in September 2007 at the Miller Creek Road intersections with the U.S. 101 Southbound Off-Ramp and Marinwood Drive. Additional a.m. peak hour counts were conducted in January 2008 at the following intersections:

• Miller Creek / Las Gallinas Avenue

• Miller Creek Middle School Driveway / Las Gallinas Avenue

• Lucas Valley Road / Las Gallinas Avenue

• Lucas Valley Road / U.S. 101 Southbound On-Ramp

• Lucas Valley Road / Miller Creek Road The counts are shown in Figure 1. During the a.m. peak hour, 113 vehicles were observed making the westbound U-turn at the Miller Creek Road / Marinwood Drive intersection. All of these U-turning vehicles are presumed to have originated from the southbound right-turn, which totals 868 vehicles during the a.m. peak hour. Field Data Collection Methodology TJKM conducted three sets of field observations during the typically congested a.m. peak period between 7:00 and 9:00 a.m. on a typical Tuesday and Wednesday in September 2007. The first observation consisted of counting vehicles traveling directly onto the southbound Miller Creek Road on-ramp (Route 1) or turning right from the off-ramp and making the U-turn at Marinwood Avenue to return to the freeway (Route 2). The second observation involved floating vehicle

runs using global positioning system (GPS) devices, in which observers followed select vehicles traveling Route 3 along Las Gallinas Avenue in the Marinwood area, in order to estimate average travel time and determine the proportion of cut-through vehicles. The third observation was following vehicles with GPS during congested periods along the U.S. 101 Southbound freeway mainline between the Alameda Del Prado and Lucas Valley Road interchanges, in order to estimate average travel time on the freeway. Congestion on the freeway was present during all observations. Floating Car Travel Time Survey Results Table 1 shows the results of the field GPS travel time surveys for the freeway mainline and three cut-through routes. A minimum of three floating runs was performed for each route. Route distances are based on the same starting and ending reference points. The start point is the Nave Drive Overcrossing upstream on the U.S. 101 Southbound freeway, which represents the beginning of the auxiliary lane between the Alameda Del Prado and Miller Creek interchanges. The ending point is the merge of the southbound Lucas Valley Road on-ramp downstream on the freeway mainline. Table 1: GPS Travel Time Results

Mr Amanuel Haile February 8, 2008 Page 5

Based on the above results, TJKM has made the following findings:

• Even though all three cut-through routes are longer in distance than the freeway mainline, Routes 1 and 2 offer on average at least one minute fifty seconds of travel time savings.

• Motorists on Routes 1 and 2 on average are traveling slightly faster than the freeway mainline, though by no more than 2.7 miles per hour (mph).

• Although motorists on Route 3 are experiencing higher travel time than the freeway mainline segment on average (66 seconds), due to the longer route distance they are traveling a slightly higher average speeds (1.4 mph).

• Although it appears that motorists on average are achieving marginal benefits by utilizing the three cut-through routes (and incurring marginal costs in time for Route 3), it is deduced that many motorists derive a psychological benefit from using these routes because they feel they are moving faster than on the freeway mainline. A closer look at the floating car data reveals that the perceived advantage is not just psychological. Most of the speed and travel time advantage is gained along the southbound freeway segment between the Nave Drive Overcrossing and the beginning of the Miller Creek Road off-ramp. On average, motorists using the approximately one-mile auxiliary lane in this segment are traveling at 27.7 mph, which is more than triple the speed of motorists traveling in the adjacent mixed-flow lanes (average of 9.0 mph). In terms of average travel time, the same comparison reveals an auxiliary lane advantage of four minutes and 23 seconds (6:26 on the mixed flow lanes minus 2:03 on the auxiliary lane). However, once motorists leave the freeway, the speed and travel time advantages are partially diminished, due to surface street congestion and additional traffic controls such as stop signs and crosswalks.

Cut-Through Route Field Observations Table 2 shows estimated proportions of the three cut-through routes based on field observations and the existing intersection turning counts. As shown in Table 2, approximately 44 percent of vehicles using the U.S. 101 Southbound off-ramp at Miller Creek Road and staying on the west side of U.S. 101 eventually return to the freeway. Based on 1,181 total observed through and right-turning volumes on the Southbound U.S. 101 Off-Ramp approach at Miller Creek Road (=313 through + 868 right turns), 26.5 percent (313/1,181) followed Route 1 directly back on to the freeway. All 113 U-turns observed at the Miller Creek Road / Marinwood Avenue intersection are assumed to follow Route 2 and originate from the off-ramp. Therefore, the Route 2 proportion is estimated to be 9.5 percent (113/1,181). The eight percent proportion for Route 3 that is shown in Table 2 was derived from the number of cars followed as part of the above mentioned floating car survey. As part of field observations of 300 vehicles during the two a.m. peak hours, TJKM observed vehicles making the westbound through movement on Miller Creek Road at Marinwood Drive. Vehicles making this movement were followed since they would potentially follow Route 3 back to the freeway. Of the potential vehicles, 20 percent actually followed the entire Route 3 from the Miller Creek Road off-ramp to the Lucas Valley Road on-ramp to U.S. 101 Southbound. This 20 percent proportion was then applied to the westbound through movement at Miller Creek Road / Marinwood Drive, since all Route 3 vehicles by definition must make this movement. Of the 495 westbound through vehicles counted during the a.m. peak hour, 99 (20 percent) would therefore be expected to follow Route 3. In turn, these 99 vehicles represent eight percent (=99/1,181) of the total southbound through and right turning volumes at the Miller Creek Road off-ramp.

Mr Amanuel Haile February 8, 2008 Page 6

TJKM evaluated the additional a.m. peak hour turning movements collected in January 2008 to determine consistency with the estimated 99 vehicles following Route 3. The following key turning movements along Route 3 were observed as follows:

• Westbound Miller Creek Road left turn at Las Gallinas Avenue: 242 vehicles

• Southbound Las Gallinas Avenue left turn at Lucas Valley Road: 172 vehicles

• Eastbound Lucas Valley Road right turn onto U.S. 101 Southbound On-Ramp: 451 vehicles The 99 vehicles expected to follow Route 3 are less than all of the above turning movements. Therefore, the Route 3 vehicle estimate is reasonable since it is completely contained within these key intersection turning movement counts. It should be noted that the 44 percent of vehicles following Routes 1, 2, or 3 does not include a secondary U-turn at Marinwood Avenue that was observed in the field. This U-turn movement includes a westbound right turn onto Marinwood Avenue, a U-turn on Marinwood Avenue itself, and then finally a left turn onto eastbound Miller Creek Road towards the southbound U.S. 101 on-ramp. Although this maneuver was observed, it was difficult to estimate precisely how many motorists did this. The likely reason that motorists made this maneuver was that they were looking for a U-turn alternative by utilizing the westbound free right turn lane at Marinwood Avenue. This would have occurred when the short segment of westbound Miller Creek Road between the two study intersections was filled with vehicles making the more conventional U-turn to return to the freeway.

Potential Design Alternatives In part based on previous observations in this study area, TJKM has developed a set of potential design alternatives that generally are intended to discourage motorists from diverting onto local streets in the Marinwood area to avoid southbound freeway congestion during the a.m. peak period. These alternatives are illustrated in Figures 2 through 6 and are described further below. It should be noted that the alternatives are presented only for discussion purposes. At this stage in the evaluation process, neither TJKM nor the County is advocating any specific alternative.

Alternative 1

Shown in Figure 2, this alternative is a design treatment that would narrow westbound Miller Creek Road between the U.S. 101 Southbound off-ramp and Marinwood Avenue to a single 14-foot lane. In addition, a Yield sign would be posted for off-ramp traffic. Currently, the pavement width in the westbound direction is approximately 42 feet, leading into a three-lane westbound approach at Marinwood Avenue. Additionally, the southbound off-ramp includes an exclusive, unrestricted free right turn.

Mr Amanuel Haile February 8, 2008 Page 7

The potential safety benefits of this alternative are:

• Narrower roadway width promotes slower speeds on Miller Creek Road and eliminates weaving of vehicles between the off-ramp and Marinwood Avenue

• Yield sign forces previously free right turn from the off-ramp to yield to Miller Creek Road traffic, reducing the potential risk of angle collisions

The potential disadvantages to traffic operations are:

• Narrower roadway width promotes slower speeds and thus increased delay on the Miller Creek Road approach to Marinwood Avenue. The time advantage of potential cut-through traffic is reduced

• Yield sign forces previously free right turn from the off-ramp to yield to Miller Creek Road traffic, increasing delay on the off-ramp for all movements

• Initially, the Yield sign may result in rear-end collisions as drivers adjust from the previously free right turn. Proper signage and advanced notices should be included during implementation.

Mr Amanuel Haile February 8, 2008 Page 9

Alternative 2

Shown in Figure 3, this alternative is a design treatment meant to specifically discourage the Route 2 cut-through movement, the westbound U-turn at Miller Creek Road / Marinwood Avenue. The treatment would shift the westbound left turn lane and adjacent median to the south and include installation of a “No U Turn” sign. This lane shift would discourage U-turns since vehicles would not be able to negotiate the turn due to a smaller available turning radius. The potential safety benefits of this alternative are:

• Eliminates westbound U-turns at Marinwood Avenue, reducing volume in the left turn lane

• Reduces weaving conflicts caused by U-turning vehicles originating from the southbound off-ramp

The potential disadvantages to traffic operations are:

• Restricts westbound U-turns and could possibly result in more cut-through vehicles using other routes, adding to travel time and delay for these vehicles.

• May induce more Route 2 cut-through vehicles to use the secondary U-turn (right turn onto Marinwood, southbound left back towards freeway)

• May temporarily add to queuing on southbound off-ramp as more cut-through vehicles divert back to Route 1 (directly back onto the freeway)

Alternative 3

Shown in Figure 4, this alternative is a design treatment that eliminates free right turns on the eastbound and westbound Miller Creek Road approaches to Marinwood Avenue. Additionally, a crosswalk and pedestrian refuge would be added to the westbound intersection approach. This alternative could be combined with the westbound left turn lane shift of Alternative 2. The potential safety benefits of this alternative are:

• Discourages use of secondary Route 2 cut-through U-turn at Marinwood Avenue described above by eliminating westbound free right turn.

• Increases pedestrian and bicycle safety and promotes pedestrian activity with the addition of the pedestrian design treatments and elimination of the free right turns.

• Slightly narrowed pavement width promotes better channelization of westbound approach traffic

The potential disadvantages to traffic operations are:

• Elimination of free right turns on Miller Creek Road adds to right turn delay and approach delay for eastbound and westbound intersection approaches

Alternative 4

Shown in Figure 5, this alternative is identical to Alternative 3, but with the additional realignment of the southbound U.S. 101 off-ramp at Miller Creek Road. This design treatment would narrow westbound Miller Creek Road immediately downstream of the off-ramp to one lane. Also, the off-ramp free right turn would be forced to stop at Miller Creek Road in the same way as the southbound left turns and through movements do currently. This alternative also could be combined with the westbound left turn lane shift of Alternative 2. The potential safety benefits of this alternative are similar to Alternative 3. In addition, the conversion of the southbound off-ramp right turn from a free movement to stop-controlled movement would reduce right turning speeds, thereby increasing intersection safety. Also, the design would create a shorter pedestrian crossing distance across the off-ramp and promote better pedestrian channelization along the north side of Miller Creek Road in the area, particularly towards the Golden Gate Transit bus stop along U.S. 101 Southbound. The potential disadvantages to traffic operations are also similar to Alternative 3. In addition, southbound off-ramp approach delay and right turn delay would increase, which initially could lead to additional queuing until cut-through traffic begins to stay on the freeway.

Alternative 5

Shown in Figure 6, this alternative is essentially a pedestrian design treatment that adds bulb-outs to all intersection approaches at the Miller Creek Road / Marinwood Avenue intersection and includes crosswalks across each approach. These bulb outs would eliminate the existing free right turns of all four intersection approaches. This alternative could be combined with the westbound left turn lane shift of Alternative 2, as well as the southbound off-ramp design treatment of Alternative 4. The potential safety benefits of this alternative are:

• Adds pedestrian crossings across all four intersection approaches.

• Shortens pedestrian crossing distances for all four intersection approaches with the elimination of all free right turns, thereby reducing pedestrian exposure to intersection vehicles.

• Discourages use of secondary Route 2 cut-through U-turn at Marinwood Avenue described above by eliminating westbound free right turn.

The main potential disadvantage to traffic operations of Alternative 5 is that approach delay and right turn delay would increase for all four approaches with the elimination of the free right turns.

Mr Amanuel Haile February 8, 2008 Page 17

In the Marinwood area, the design alternatives presented above may be most effective in eliminating cut-through Routes 1 and 2. As for Route 3, speeding may be an issue since average speed is greater than on the freeway, even though average travel time is also greater. Some of the eight percent of motorists utilizing Route 3 may speed along some segments of the route to make up for lost time along other segments where average speed is lower due to congestion and traffic controls. Therefore, the potential education and enforcement measures mentioned above are more likely to discourage this cut-through route than engineering measures. It should be noted the five alternatives presented are not necessarily stand-alone design treatments and can be combined with one another. For example, Alternative 4, which forces southbound off-ramp right turns into stop control at Miller Creek Road and eliminates eastbound and westbound free right turns at Miller Creek Road / Marinwood Avenue, could be combined with Alternative 2. Alternative 2, which only shifts the westbound left turn median at Marinwood Avenue, could be integrated with Alternative 4 since they are complementary design treatments. TJKM appreciates the opportunity to present preliminary cut-through traffic evaluation results and preliminary traffic calming design alternatives. If you have any questions, please call us at (925) 463-0611. Thank you. Sincerely,
