Development of a model performance-based sign sheeting specification based on the evaluation of nighttime traffic signs using legibility and eye-tracker data

Description: "This report focused on the evaluation of traffic sign sheeting performance in terms of meeting the nighttime driver needs. Using the luminance requirements derived from the study and market-weighted headlamp flux matrices, the researchers developed an approach to sigh sheeting specification that is based on nighttime driver needs."

Use of Intelligent Transportation Systems in rural work zones

Description: "This project defined an approach to integrating data collected and traveler information displayed in a work zone with a regional transportation management center and/or other state websites. The project conducted a literature review to define the state of the practice in work zone Intelligent Transportation Systems (ITS; smart work zones) and worked with the Texas Department of Transportation traffic managers to identify their safety and nobility needs in a work zone and where ITS can play a role."

Peer grouping and performance measurement to improve rural and urban transit in Texas

Description: "Rural and small urban transit systems in Texas will become even more important with predicted changes in population trends. Rural demographic trends indicate growth in the number of persons age 65 and over coupled with a decrease in population density. Small urban area trends indicate substantial population growth and broadened geographic boundaries, yet resources to provide rural and small urban transit are limited. Therefore, transit managers find it is increasingly important to maximize service efficiency and effectiveness. The purpose of this research was to identify peer groups, performance benchmarks, and strategies used by successful transit providers to achieve high performance. The research project identifies peer groups based on the transit environment within which each agency operates, so that agencies can be compared to other operators who face similar environments. Peer group effectiveness and efficiency performance are examined within and between rural and urban peer groups, and high performers are identified for case studies. Through the case studies, key attributes are identified for achieving high operating efficiency and/or effectiveness. Performance strategies are categorized to provide transit providers with transferrable information to improve performance and increase the return on transit investment."

Delivery of workshops on corridor management and preservation in Texas

Description: "This report summarizes the delivery and outcome of a series of workshops conducted at 23 Texas Department of Transportation (TxDOT) districts across the state on corridor management and preservation in Texas. The workshops served as follow-up implementation work for research project 0-5606, "Creating Partnerships with Local Communities to Manage and Preserve Corridors." The report provides an overview of the project and documents the dates, locations, and attendance of workshops implemented during the three-year project period."

Estimated impacts of the 2010 census on the Texas transit funding formula

Description: Changes in the population and land area of urbanized areas in Texas will play a significant role in determining the allocation of public transportation funds to service providers in Texas after Census 2010. The purpose of this research report is to review the impacts of the changes in urbanized area population and non-urbanized (rural) population and land area for 2010 on the current Texas Transit Funding Formula for allocation of Federal Section 5311 and state rural and urban funds. This collaborative effort between the Texas Transportation Institute and the Institute for Demographic and Socioeconomic Research at the University of Texas at San Antonio draws upon the complementary expertise of public Transportation planners, demographers, and geographic information systems professionals of the two research organizations. The research project identifies areas with the potential to exceed 200,000 in population and those non-urbanized areas that have potential to become urbanized (over 50,000 people) in 2010. The implications of these changes will be examined relative to the current public transportation funding allocations. The research staff provides a comprehensive assessment of these changes for the state as a whole and for individual transit service providers.

Traffic signal operations handbook workshop series : final report

Description: This report documents the development and conduct of a two-year series of workshops to share information with Texas Department of Transportation (TxDOT) engineers and technicians regarding the cost-effective design and operation of traffic signals at intersections along state highways in Texas. The workshop was one day in length and was offered at six venues in Texas. Workshop topics include basic signal controller timing, coordination timing, signal phasing, rail preemption, detection design, and diamond interchange timing. The workshop participants applied guidelines from the Traffic Signal Operations Handbook in several examples using a spreadsheet program called the Texas Signal Coordination Optimizer (TSCO).
