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."

Quantitative characterization of microstructure of asphalt mixtures

Description: "The main objective of this study was to quantitatively characterize the three dimensional micro-structure of the asphalt binder withing the fine aggregate matrix of an asphalt mixture and compare the influence of binder content, coarse aggregate gradation, and fine aggregate gradation on this micro-structure."

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."

Internal trip capture estimator for mixed-use developments

Description: This report describes a spreadsheet tool for estimating trip generation for mixed-use developments, accounting for internal trip capture. Internal trip capture is the portion of trips generated by a mixed-use development that both begin and end within the development. The importance of internal trip capture is that those trips satisfy a portion of the total development's trip generation and they do so without using the external road system. As a result, a mixed-use development that generates a given number of total trips creates less demand on the external road system than single-use developments generating the same number of trips. This report describes the spreadsheet estimator and how to use it. It describes the data behind the estimator as well as how those data are applied. The two Texas mixed-use developments from which most of the data were derived are also described. This report is supplemented by the Excel® spreadsheet itself as well as task memoranda that document the survey data collected as part of this project.

Water Issues in Texas : A Survey of Public Perceptions and Attitudes about Water

Description: "The Texas AgriLife Extension Service facilitated a random sample survey of Texas residents to evaluate their awareness of, attitudes about and willingness to act on water issues. The results of this survey will be useful to citizens, local governments, state agencies and policy makers in planning for the future" (p. 6).

Highway safety design workshops

Description: Highway safety is an ongoing concern for the Texas Department of Transportation (TxDOT). As part of its proactive commitment to improving highway safety, TxDOT is moving toward including quantitative safety analyses earlier in the project development process. To assist in achieving this goal, TxDOT research project 0-4703 developed the Roadway Safety Design Workbook for engineers responsible for highway geometric design. This Workbook describes quantitative safety relationships for specific design components known to be correlated with crash frequency. As part of TxDOT Project 0-4703, a series of workshops were developed to share safety information with TxDOT roadway designers. Information in the Workbook was used as the basis for the workshops. The workshops addressed rural highways, urban streets, and freeways. They included a mixture of classroom discussion and hands-on training activities for the participants. The participants indicated that the information presented in the workshops will be beneficial as they make decisions about highway safety improvements.

Texas Urban Triangle: creating a spatial decision support system for mobility policy and investments that shape the sustainable growth of Texas

Description: "This project came into being due to the dramatic transformation of the four core Texas metropolitan areas into an emergent megalopolis: Dallas-Fort Worth, Houston, San Antonio, and Austin. Its aims are two-fold: to provide a framework for decisions about future growth in the fastest growing region of Texas, and to spur further research into the complexities of this vast and rapidly emerging mega-region. The Texas Urban Triangle - 17 million persons spread over 58,000 square miles - is a new urban phenomenon, a triangular megalopolis whose development is not linear and contiguous. This report gives policy makers and investors from all sectors of society the critical knowledge they need to make decisions that will shape the future of Texas. The Texas Urban Triangle is one of the most dynamic urban regions in the nation, and to ensure it continues to flourish, we must build a future based on sustainable growth principles. Our preliminary findings suggest that this is not always the case. Further research needs to be conducted to obtain a complete, detailed, and comprehensive portrait. Nonetheless, even these preliminary findings are robust and point to more sustainable options for the future. Now that this preliminary analysis has been completed, readers are invited to consider the results. The ultimate goals of the project are three-fold: To plant the Texas Urban Triangle squarely and firmly into the public imagination of Texans far and wide - to put the Texas Urban Triangle "on the map." To provide a basis for current policy and planning decisions so that a more vibrant and attractive "Heart of Texas" - its metropolises, counties, and cities - provides a more sustainable environment for its residents, and their descendents [sic] and newcomers, well into the future. To determine what future research, particularly at the regional scale, is needed ...

Hydraulic capacity of type-h inlets: final report

Description: Type H Inlets are frequently used by the Texas Department of Transportation as median drains for divided highways. Despite frequent use, engineers do not have adequate design information to mathematically describe the hydraulic performance of these structures. Typically, it has been assumed that IL-H-G and IL-H-L function essentially the same as roadway grates or curb inlets, but there is no basis for that assumption. Type-H drop inlets were investigated using a database from literature-reported experiments for similar inlets and physical model studies conducted at Texas Tech University (TTU). SWMM was investigated as a predictive tool by comparison to the TTU experimental results. The SWMM model was subject to very minimal calibration yet predicted performance reasonably well, especially when full inlet capture may occur. Examples of performance prediction using HEC-22, the power-law model and SWMM are presented to provide some guidance for Type-H inlet design.
