Peer grouping and performance measurement to improve rural and urban transit in Texas
"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." texashistory.unt.edu/ark:/67531/metapth303468/

Potential connected vehicle applications to enhance mobility, safety, and environmental security
"Researchers first conducted a comprehensive review of the state-of-the-art connected-vehicle research and technologies. Once researchers had a thorough understanding of the technology, they focused on selecting and developing the near-term practical applications that use connected vehicle technology. The research team then sought expert opinions from the Texas Transportation Institute working group during two brainstorming sessions, which produced two lists of potential applications and prioritized the applications based on deployment feasibility. In particular, a total of five applications were selected for development of the full concept of operations, including two in safety, two in mobility, and one in environmental security. These applications address various problems, including wrong-way driving and unprotected-grade-crossing crashes (safety): work-zone merge efficiency and safety, and freeway speed harmonization (mobility): and slippery pavement-related crashes (environmental security)." texashistory.unt.edu/ark:/67531/metapth281728/
Project report on the continued development and analysis of the Flexible Pavements Database
"The efforts of 0-6275 were primarily twofold. One aspect was geared towards extensive performance monitoring and material testing for better characterization of the experimental sections included as part of 0-5513 as well as new sections that were to be incorporated in the enhanced version of the TFPD. The other aspect of the study was to look into the calibration of the transfer functions in the newly developed MEPDG as well as Texas ME Design procedure being sponsored by TXDOT through the 0-5798 research study. It was understood that an effort to determine reliable bias correction factors would necessitate a large volume of project specific information for a number of pavement sections that are well spread out within the state such that differences in materials, traffic, construction practices and climate are captured. The TFPD supplemented by other databases like the DCIS and the LIMS will ensure that the data needs for the calibration exercise are met and fulfilled to the extent possible. When time series data were not available, the researchers utilized relevant data from the FHWA's Long Term Pavement Performance Studies (LTPP). This interim report summarizes the activities performed during the first 7 months of the project, when the current project was terminated. Therefore, this document reports on the work performed in Tasks 1 through 7. texashistory.unt.edu/ark:/67531/metapth281719/

Manual for Assessing Safety Hardware test 3-11 on the Texas T101 bridge rail
The Texas T101 bridge rail is widely used in the state of Texas. Previous testing demonstrated its ability to contain and redirect passenger cars and a 20,000-lb school bus. Based on this testing, the Federal Highway Administration accepted the T101 bridge rail as an NCHRP Report 350 TL-3 barrier. However, its impact performance with pickup trucks was never evaluated. Under research project 0-5526, Impact Performance of Roadside Safety Appurtenances, researchers conducted a performance assessment of Texas roadside safety devices to help evaluate the impact of adopting the new AASHTO Manual for Assessing Safety Hardware (MASH) guidelines on current hardware. Testing and evaluation of the T101 bridge rail was recommended as a high priority. This recommendation was based primarily on the absence of pickup truck testing on the system, and concerns that the 27-inch rail height may not be compatible with pickup trucks and SUVs under design impact conditions. The T101 bridge rail did not meet MASH evaluation criteria for test 3-11. The vehicle overturned after losing contact with the barrier. texashistory.unt.edu/ark:/67531/metapth303688/
Development of a MASH TL-2 guardrail-to-bridge rail transition compatible with 31-inch guardrail
The TxDOT Design Division is in the process of developing new guardrail standards that comply with the AASHTO Manual for Assessing Safety Hardware (MASH). The new guardrail system will provide increased capacity and improved impact performance relative to the current design. A key feature of the new system is an increased in rail mounting height from 27 inches to 31 inches. TxDOT's current TL-2 metal beam transition is 27 inches tall and is not compatible with the new 31 inch guardrail system. While the high-speed, nested thrie beam transition system meets MASH guidelines and is compatible with a 31-inch guardrail, it would be cost-prohibitive to use it on all roadways. The objective of this research was to develop a transition that is suitable for use on lower speed roadways, less expensive and complex than the current high-speed (i.e., TL-3) transition design, and is compatible with a 31-inch guardrail. A low-cost guardrail-to-bridge rail transition was successfully developed and tested under MASH Test Level 2 conditions. It is compatible with a 31-inch guardrail and can connect to rigid concrete bridge rails. It is considered suitable for implementation on roadways that have traffic conditions appropriate for the use of TL-2 safety hardware. Use of this system provides significant savings in material and installation cost compared to the high speed transition system. texashistory.unt.edu/ark:/67531/metapth326771/

MASH test 3-11 on the 5-inch cast in place deck barrier anchors
"A full-scale crash test was performed to evaluate the impact performance of a Texas T223 concrete beam and post bridge rail anchored to a 5-nch cast-in-place deck (CIPD). The testing followed the MASH standards for Test Level 3 ( TL-#) longitudinal barriers. The test performed was American Association of State Highways and Transportation Officials (AAHSTO) Manual for Assessing Safety Hardware (MASH) test 3-11, which involves a 2270P (500 lb) pickup truck impacting the critical impact point (CIP) of the barrier at a nominal impact speed and angle of 62 mi/h and 25degress, respectively. This test evaluated the strength of the barrier and its anchorage to the 5-inch CIPD." texashistory.unt.edu/ark:/67531/metapth326631/

Report discussing the findings of a study into issues related to roadside safety devices: "The objective of this study was to develop a suitable replacement for the downstream 'turn-down' guardrail anchor system. The 'turn-down' guardrail anchor system does not meet mandated test requirements under MASH for upstream anchor application terminals; however, it does meet downstream requirements for previous crash testing standard" (abstract). It includes background information, system details, test requirements and evaluation criteria, crash test procedures, crash test results, and conclusions. texashistory.unt.edu/ark:/67531/metapth326630/
Determination of minimum height and lateral design load for MASH test level 4 bridge rails
"This research had the objectives of determining the minimum rail height and lateral design impact load for MASH test level 4 bridge rails. Using parametric finite element analysis and subsequent crash testing, the researchers determined the minimum recommended rail height for MASH TL-4 impact conditions to be 36 inches. Later Design impact for MASH TL-4 test conditions was determined to be 80 kips." texashistory.unt.edu/ark:/67531/metapth326629/

Internal trip capture estimator for mixed-use developments
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. texashistory.unt.edu/ark:/67531/metapth303689/

Highway safety design workshops
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. texashistory.unt.edu/ark:/67531/metapth303691/
