Flood Protection Plan: Phase 2

Description: "The purpose of this study was to expand on the Phase I City of Brownsville Flood Study that was developed in 2006 to expand the study area to include two additional Brownsville watersheds in the Northwest quadrant of the City and to create a linked watershed model to allow for the investigation of inter watershed transfers of storm-water flow between the watershed studied in 2006. This study analyzes several of the gaps identified in the 2006 Flood Study by 1) developing baseline models to assess existing flooding risks in the Resaca del Rancho Viejo (RRV) and Cameron County Drainage District No.1 Ditch No.3 (CCDD#) watersheds; 2) examining the impact of storm surge on each watershed; and 30 linking the hydraulic models for those watershed that are hydraulically linked. This study, like the 2006 study, is meant for planning use only and should not be used for engineering design purposes" (p. ii).

U.S. and Texas international trade and transportation

Description: "This report examines various aspects of international trade, transportation, and foreign practices implemented to facilitate and fund transport-related infrastructure. The report is composed of six chapters. The first chapter provides an overview of the U.S. international trade outlook. The second chapter describes the roles played by air cargo transport, ports and ocean carriers, railroads, and the motor carrier industry in U.S. international trade. The third and fourth chapters focus on Texas-specific international trade and modal gateways. The fifth chapter reviews various transport funding mechanisms, Intelligent Transportation System (ITS) applications, and forms of public-private partnerships adopted in various foreign countries. The final chapter describes the expansion of the Panama Canal and its likely Texas impacts."

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."

Exploratory study : vehicle mileage fees in Texas

Description: 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.

Potential connected vehicle applications to enhance mobility, safety, and environmental security

Description: "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)."
