16. Abstract This report documents the results of the traffic data collection efforts during the first year of

reconstruction on the US-75 North Central Expressway south of the 1-635 LBJ Freeway. Traffic conditions and patterns were monitored during October 1990 {approximately five months after the start of the reconstruction project) and during May 1991 (approximately one year after the start of the project). The traffic monitoring efforts include traffic data collection and automobile and transit user surveys. The traffic data collection efforts included screen line traffic volume counts, vehicle occupancy and classification counts, and travel time runs. The automobile and transit users surveys are documented elsewhere. The results indicate that the reconstruction activities underway during the October 1990 and May 1991 data collection efforts had little impact on traffic conditions and patterns in the corridor.

SUMMARY

This report documents the results of the traffic data collection efforts during the first year of reconstruction on the US-75 North Central Expressway south of the 1-635 LBJ Freeway. Traffic conditions and patterns were monitored before construction (October 1989 and May 1990) and during construction (October 1990 and May 1991). The traffic monitoring efforts include traffic data collection and automobile and transit user surveys. The traffic data collection efforts included screen line traffic volume counts, vehicle occupancy and classification counts, and travel time runs. The automobile and transit users surveys are documented elsewhere.

The results indicate that the reconstruction activities underway during the October 1990 and May 1991 data collection efforts had little impact on traffic conditions and patterns in the corridor. These results are consistent with the findings of the automobile users survey. The results of the traffic data collection efforts can be summarized as follows:

o No major changes in traffic patterns occurred throughout the North Central corridor during the first year of the reconstruction project, based upon comparisons of October 1989 versus October 1990 screen line counts and May 1990 versus May 1991 counts.

o Peak-period traffic on the US-75 North Central Expressway consists primarily of passenger vehicles (93-96 percent) of which 83-90 percent carry only a single-occupant.

o Average travel times on the US-75 North Central Expressway between the 1-635 LBJ Freeway and the Dallas central business district were 2-3 minutes longer during the first year of the reconstruction project than before the project.

INTRODUCTION

This report documents the continuing efforts by the Texas Transportation Institute (TTI) to monitor the changes in traffic conditions and travel patterns that result from the reconstruction of the US-75 North Central Expressway south of the 1-635 LBJ Freeway. The reconstruction project began during the Summer of 1990 and is continuing into its second year. This report documents traffic conditions during the first year of reconstruction (October 1990 and May 1991 data collection efforts).

TTI began monitoring the North Central corridor during October 1989 and, since that date, has been collecting data twice per year (in May and October). The monitoring effort has two major elements:

o Collection of traffic data, and o Survey of automobile and transit users.

A previous report documented traffic conditions and patterns in the corridor before construction in October 1989 and May 1990 (1). The results of the May 1990, November 1990, and May 1991 automobile and transit users surveys are summarized in separate reports (2-4).

The data reported herein, together with the data collected in subsequent studies, will aid in determining the changes in traffic conditions and travel patterns associated with the reconstruction of the US-75 North Central Expressway. The monitoring plan was designed to provide data for several potential uses:

o Traffic management planning for future phases of the North Central project and for future projects in the Dallas area,

o The development of optimal signal timing plans for the arterial streets in the corridor,

o Public affairs programs to inform the public about traffic conditions and travel alternatives,

o DART bus route and schedule planning, o Validation of portions of the North Central Texas Council of Governments

(NCTCOG) peak hour traffic model, and o Development of a traffic simulation model of the North Central corridor for

evaluating proposed traffic management actions.

The body of this report is divided into three sections. First, the traffic monitoring plan is reviewed. Then, two separate sections summarize observed conditions during October 1990 and May 1991.

1

TRAFFIC MONITORING EFFORT

This section describes the plan for monitoring the changes in corridor traffic conditions and travel patterns that result from the reconstruction of the US-75 North Central Expressway south of the 1-635 LBJ Freeway. The monitoring effort has two components: (1) traffic data collection, and (2) automobile and transit users survey.

Traffic Data Collection

The traffic data collection effort has three components:

o Screen line traffic volume counts, o Vehicle occupancy and classification counts, and o Travel time runs.

The monitoring effort closely follows the boundaries of the North Central corridor that were defined by the North Central Mobility Task Force:

o 1-635 LBJ Freeway on the north, o The Dallas central business district on the south, o Audelia, White Rock Lake, and Buckner on the east, and o The Dallas North Tollway on the west.

Data are collected two times during the year, and at the same time of the year (May and October). In order to control for seasonal variations in traffic conditions and patterns, the principal comparisons are among data collected during the same month of the year (e.g., October 1989 versus October 1990, and May 1990 versus May 1991).

Screen Line Traffic Volume Counts

Screen line traffic volume counts are used to monitor traffic patterns throughout the corridor. A screen line is a line drawn either north-south or east-west through the corridor; counts are taken on each route crossing the screen line. The sum of the traffic volume counts along the screen line is the total corridor traffic volume. Changes in traffic patterns are measured as changes in individual routes' percentage of the total corridor traffic volume.

Traffic patterns are being monitored at four screen lines, which are designated by the routes along which the screen lines run: Loop 12, Mockingbird/Buckner, Oak Lawn/Lemmon/Peak, and US-75 North Central Expressway. Three screen lines (Loop 12, Mockingbird/Buckner, and Oak Lawn/Lemmon/Peak) are being used to identify changes in traffic patterns on north-south routes. The US-75 screen line, which bisects the Expressway, was established to measure changes in east-west traffic patterns. The count locations for the October 1990 and May 1991 data collection efforts are identified in Figure 1.

The October 1989 study was restricted to the screen line south of Mockingbird/ Buckner. The May 1990 study, the principal data collection effort before construction, included all four screen lines. The October 1990 study, the first data collection effort during construction, focused on the northern half of the corridor which would be most affected by the construction activities that were underway at the time on the N 1 and N2 segments of the North Central project. The May 1991 study closely resembled the May 1990 data collection effort.

Vehicle Occupancy and Classification Counts

Vehicle occupancy and classification data were collected on the US-75 mainlanes north of the Mockingbird/Buckner screen line during both the May 1990 and October 1990 studies. The count location is identified in Figure 1.

Vehicles were grouped into four categories: passenger vehicles, commercial vehicles, buses, and motorcycles. Passenger vehicles included all cars as well as all pickup trucks and vans that had no commercial identification.

Travel Time Runs

Peak period travel times and speeds are being monitored on major north-south routes in the corridor as well as the east-west routes along which the screen lines run. Data are collected using the floating car technique in which the data collection vehicles are driven at the median speed of the traffic stream along the routes (by passing as many vehicles as pass them). All routes extend between the 1-635 LBJ Freeway and the Dallas central business district.

Data collection vehicles start at each end of the corridor at half-hour intervals from 6:00 to 9:00 A.M. and 3:00 to 7:00 P.M. Travel times are measured between each pair of signalized cross streets and for the entire route. Stopped delays are also recorded at the signalized intersections. The distance between each signalized intersection was measured using a vehicle-installed distance measuring instrument in order to compute average travel speeds. Peak hour average travel times and average travel speeds are computed for the AM. peak using the 7:00, 7:30, and 8:00 AM. travel time runs, and for the P.M. peak using the 5:00, 5:30, and 6:00 P.M. runs.

Table 1 summarizes the travel time routes and the number of repetitions on each route during the four monitoring efforts. The street name appearing in bold-face type represents the major street on each alternative route and is used to designate the route.

During October 1990, six routes were monitored. During May 1991, nine routes were monitored; Hillcrest also would have been monitored, if it had not been closed for repairs between Loop 12 and Lovers Lane. Figure 2 highlights the travel time routes.

Automobile and Transit User Surveys

Surveys of automobile and transit users in the North Central corridor have been conducted as part of the May 1990, October 1990, and May 1991 monitoring efforts. Panel members {i.e., automobile and transit users who agreed to be surveyed biannually) were recruited from license plate and onboard bus surveys conducted during May 1990 at the Loop 12 screen line.

The role of the surveys in the overall monitoring effort is to help explain the observed changes in traffic conditions and patterns. The surveys obtain information on the perceptions and travel behavior of individual automobile and transit users in the corridor. Periodically surveying the same panel members permits changes in individual perceptions and behavior to be tracked. Details of the surveying effort and results are documented in other reports (2-4).

OCTOBER 1990 CONDITIONS

This section compares traffic conditions and patterns during October 1989 (before construction) and October 1990 (approximately five months after the start of the North Central project). The October 1989 data collection effort was documented in an earlier report (1). Summaries of all data collected during October 1990 are presented in Appendices A through E.

Screen Line Volumes

The October 1990 screen line volume counts are summarized in Appendices A, B, and C. Appendix A contains tables summarizing the hourly volume counts on each route at each screen line. Appendix B contains figures summarizing each route's percentage of the total screen line volume; separate figures are presented for each of four screen lines and each of three time periods: A.M. peak (6:00-9:00 A.M.), P.M. peak (3:00-7:00 P.M.), and 24 hours. Appendix C contains figures that summarize the actual change in volumes on each route along the Mockingbird/Buckner screen line from October 1989 to October 1990.

During October 1989 traffic volume data were collected only at the Mockingbird/ Buckner screen line. Therefore, comparisons between October 1989 and October 1990 can be made only at that screen line. Figures B-4 through B-6 in Appendix B include both the October 1989 and October 1990 data for the Mockingbird/Buckner screen line.

Figure B-6 summarizes the percentage of the total 24-hour screen line volume by route for the Mockingbird/Buckner screen line. US-75, which carries 35 percent of the traffic, and the Dallas North Tollway (ONT), with 20 percent, are the major routes at the Mockingbird/Buckner screen line. There were only minor differences (less than 2 percent) in any route's percentage of total screen line volume between October 1989 and October 1990. Figures B-4 and B-5 for the A.M. and P.M. peak periods, respectively, show similar results. These results are consistent with the automobile user survey results which indicate only very small changes in traffic patterns from October 1989 to October 1990 (3).

Vehicle Occupancy and Classification

Table 2 summarizes the average occupancy of passenger vehicles on the US-75 North Central Expressway during the May 1990 and October 1990 studies. Most automobile users on the Expressway drive alone. During the A.M. peak period, the percentage of single-occupant vehicles increased from 85 percent in May 1990 to 90 percent in October 1990, and therefore the average passenger vehicle occupancy decreased ·from 1.20 to 1. 12 persons per vehicle. During the P. M. peak period, the percentage remained at 83 percent, and the average passenger vehicle occupancy decreased slightly from 1.22 to 1.21.

Table 3 summarizes the vehicle classification data. The peak period, peak direction vehicle mix in the corridor averaged 93-96 percent passenger vehicles, 3-5 percent commercial trucks, and 1 percent other (bus and motorcycle). Only the May 1990 percentages of passenger vehicles and commercial vehicles for the northbound direction during the AM. peak period differ from these averages.

Travel Times and Average Travel Speeds

Average peak hour, peak direction travel times and travel speeds are shown in Figures 3 and 4, respectively. Average travel times during both the A.M. and P.M. peaks range between 20 and 30 minutes on most routes except the Dallas North Tollway on which travel times are approximately 15 minutes. Average speeds, therefore, are higher on the Dallas North Tollway than on the other routes. Average speeds on the Dallas North Tollway decreased by approximately 5 mph ·from October 1989 to October 1990.

Average travel times on US-75 increased by approximately 3 minutes in the A.M. peak period, which is the same change reported in the automobile users survey (3). The 4-minute decrease in observed travel times during the P.M. peak period differs from the 3-minute increase reported in the survey results (3). This discrepancy in the P.M. peak period results is probably due to an incident during the 5:30 p.m. travel time run of the October 1989 study that made the average travel time higher than normal.

Greenville was the only other route on which changes in average travel times and speeds were observed. Several incidents occurred during the October 1989 Greenville travel time runs for the P.M. peak period. Therefore, the average travel time for October 1989 was higher than for the October 1990 runs during which no incidents occurred.

Appendix D contains tables and figures summarizing the A.M. and P.M. peak period travel times along each route during October 1990. Appendix E contains tables and figures that summarize the corresponding average travel speeds.

MAY 1991 CONDITIONS

This section compares traffic conditions and patterns during May 1990 (before construction) and May 1991 (1 year after the start of construction). The May 1990 data collection results were presented in an earlier report (1). Summaries of all data collected during May 1991 are presented in Appendices F through J.

Screen Line Volumes

Appendix F contains tables summarizing the May 1991 hourly volume counts on each route at each screen line. Appendix G contains figures summarizing each route's percentage of total screen line volume in both May 1990 and May 1991; separate figures are presented for each of four screen lines and each of three time periods: A.M. peak (6:00-9:00 A.M.), P.M. peak (3:00-7:00 P.M.), and 24 hours. Appendix H contains figures that summarize the actual change in volumes on each route from May 1990 to May 1991 at each screen line.

Traffic Patterns on North-South Routes

Few major changes in north-south traffic patterns occurred from May 1990 to May 1991. No route's percentage of the 24-hour screen line volume changed by more than approximately 1 percent. The fluctuations in A.M. and P.M. peak period percentages were slightly larger (but generally less than 3 percent).

The screen line volume counts do not indicate any significant shift away from US-75 due to the construction underway during May 1991. By way of comparison, the automobile users survey results show a larger reduction in the percentage of panel members using US-75 (4-6 percent) than the screen line counts indicate (approximately 1 percent) in the A.M. and P.M peak directions (4). The automobile users panel intentionally overrepresents US-75 users (i.e., the percentage of panel members that use US-75 is higher than US-75's percentage of the total corridor volume); and this fact may explain the larger reported percentage reduction in utilization of US-75.

Traffic Patterns on East-West Routes

East-west traffic crosses US-75 on eighteen routes between the 1-635 LBJ Freeway and the Woodall-Rogers Freeway. Ten of the eighteen routes carry at least 5 percent of the total 24-hour east-west traffic. Loop 12 is the major east-west route, carrying approximately 15 percent of the 24-hour screen line volume.

Figures G-10 through G-12 and H-10 through H-12 suggest changes in east-west traffic patterns from May 1990 to May 1991. The most substantial change occurred on Forest where westbound traffic decreased during May 1991. This reduction in traffic was most likely due to lane closures on Forest during the reconstruction of the US-75 and Forest interchange.

Travel Times and Average Travel Speeds

Figures 5 and 6 show average peak-hour, peak-direction travel times and travel speeds on the north-south routes in the North Central Expressway corridor. Overall, the construction underway on the N1 and N2 sections during the May 1991 travel time runs appears to have had little effect on travel times and speeds.

Traffic on the US-75 mainlanes was not significantly affected by the construction activities underway during the May 1991 travel time runs. There were small increases in average travel time (less than 2 minutes) and decreases in average travel speeds (less than 1 mph) from May 1990 to May 1991. Average speeds on the US-75 frontage roads actually increased from May 1990 to May 1991. By way of comparison, the automobile users survey results indicate small decreases in average travel times from May 1990 to May 1991 for both US-75 users and users of other routes in the corridor (4).

The Dallas North Tollway had the highest average speed of any north-south route in the corridor. Average speeds on the Tollway increased from May 1990 to May 1991. This increase may be attributable to the increased utilization of toll tags and provision of a toll-tag-only lane at the main barrier toll plaza beginning in November 1990.

Minor fluctuations in travel times and speeds occurred on the arterial streets, but they appear unrelated to the US-75 construction. Most of the changes can be explained by incidents or inclement weather during either the May 1990 or May 1991 travel time runs.

Appendix I contains tables and figures summarizing the AM. and P.M. peak period travel times along each route during May 1990 and May 1991. Appendix J contains tables and figures that summarize the corresponding average travel speeds.
