This report summarizes the activities conducted on a variety of topics for the Texas Department of Transportation (TxDOT), Houston District. The Texas Transportation Institute (TTI) conducted the following studies on the High Occupancy Vehicle (HOV) Lanes: field studies on five HOV facilities to measure vehicle occupancies, volumes, and travel times; vehicle counts at twenty-nine park and ride facilities to determine usage rates. TTI developed justification statements for ramp metering, road user cost analyses for U.S. 59, and traffic analyses for the Memorial City area on I-10 Katy Freeway. The project staff developed and conducted specific traffic analyses in the South Main/Texas Medical Center area to measure travel times and origin/destination patterns to address mobility and potential transportation improvements. There were two efforts in Freeway Incident Management: 1) development of Geographical Information Systems (GIS) for traffic management application; and 2) monitoring and evaluation of the Motorist Assistance Program (MAP). TTI conducted urban planning studies on over 7600 sections of roadway for inventory statistics, travel time and speed parameters, and vehicle classification data. TTI collected general traffic data collections to maintain the Houston District database and to support the road user cost analyses made for specific areas. The project staff conducted the following studies: a public information study on Houston mobility and safety at the Houston Auto Show; focus groups to select a "formal" name for Houston's new Traffic Management Center (Houston TranStar); and development of an informational brochure for the opening of the Fred Hartman Bridge in Baytown, Texas. TTI conducted significant work for the central control system design: software development of Houston TranStar and coordinated efforts with TxDOT and their Systems Integrator, Loral, in multiple aspects of preparing for the opening of the traffic management center. TTI continued the development of the Houston AVI - Phase 2 program with the recruitment of 3,000 volunteers to serve as AVI probes. TTI provided technical assistance to TxDOT in the preparation of proposals, work orders, and other documentation in conjunction with the development of several cooperative projects with the Federal Highway Administration as well as other local transportation agencies

A multi-disciplinary approach to transportation planning fundamentals The Transportation Planning Handbook is a comprehensive, practice-oriented reference that presents the fundamental concepts of transportation planning alongside proven techniques. This new fourth edition is more strongly focused on serving the needs of all users, the role of safety in the planning process, and transportation planning in the context of societal concerns, including the development of more sustainable transportation solutions. The content structure has been redesigned with a new format that promotes a more functionally driven multimodal approach to planning, design, and implementation, including guidance toward the latest tools and technology. The material has been updated to reflect the latest changes to major transportation resources such as the HCM, MUTCD, HSM, and more, including the most current ADA accessibility regulations. Transportation planning has historically followed the rational planning model of defining objectives, identifying problems, generating and evaluating alternatives, and developing plans. Planners are increasingly expected to adopt a more multi-disciplinary approach, especially in light of the rising importance of sustainability and environmental concerns. This book presents the fundamentals of transportation planning in a multidisciplinary context, giving readers a practical reference for day-to-day answers. Serve the needs of all users Incorporate safety into the planning process Examine the latest transportation planning software packages Get up to date on the latest standards, recommendations, and codes Developed by The Institute of Transportation Engineers, this book is the culmination of over seventy years of transportation planning solutions, fully updated to reflect the needs of a changing society. For a comprehensive guide with practical answers, The Transportation Planning Handbook is an essential reference.
