"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."

This project evaluates Vehicle Mileage (VM) fees as a possible funding mechanism for meeting the State of Texas' long-term transportation needs. Researchers conducted listening sessions with the general public and stakeholders to gather input on the concept. Researchers also prepared a decision matrix that can aid policy makers in evaluating the various trade-offs in policy that will be encountered in vehicle mileage fee system development. This study identified both challenges and opportunities for implementation of VM fees.

Technical report examining two strategies were investigated to ensure pedestrian clearance time in intersections near highway-rail grade crossings. The first utilizes a lower-level preemption sequence to guarantee full pedestrian clearance to a terminating phase before the traffic signal starts the preemption sequence. The second strategy uses the pedestrian-omit feature to prevent the controller from activating the pedestrian interval if there is not sufficient time in advance of the start of the preemption sequence to provide full pedestrian clearance.

"This report summarized the series of "Traffic around Schools"" workshops conducted throughout the state of Texas to familiarize TxDOT employees and partner agencies with two key products from previous research projects (0-4286 and 0-5470) and other tools and guidance that are available for dealing with problems around schools."

Report on research performed on the application of instruments including accelerometers and tiltmeters to monitor bridge scour. The instrumentation on the two bridges does not show great hope of application of accelerometers to monitor bridge scour because of a lack of sufficient excitation from traffic. Tiltmeters can provide the integral behavior of the bridge, and therefore are very useful devices for scour monitoring. Guidelines and protocols for scour monitoring based on the US59 over Guadalupe River Bridge and the SH80 over San Antonio River Bridge are provided in the study.

This report describes a project to develop a global approach that would reduce the level of uncertainty associated with unknown foundations.

This report describes the current state of practice of microsurfacing in Texas and compares it to best practices extracted from existing literature. A survey of DOT personnel, contractors and emulsion suppliers in Texas provides insight into the most crucial factors contributing to the success or failure of a microsurfacing. From the results of the survey, literature reviews, case studies and site visits, the research team analyzed material selection and mix design methods, construction practices, equipment practices and performance measures for microsurfacings.

"An instrumented, simulated bridge pier was constructed, and two full-scale collisions with an 80,000-lb van-type tractor-trailer were performed on it. The trailer was ballasted with bags of sand on pallets. The simulated pier was 36 inches in diameter and was supported in the longitudinal direction by two load cells. Force-versus-time data were obtained from the load cells."
