Preserving the Functionality/Asset Value of the State Highway System: Technical Report

摘要

Maintaining, preserving, and enhancing the functionality of state and local roadways of our transportation system is important because it maintains capacity and efficiency, reduces potential for congestion, maintains safety, reduces the need for further (or unplanned) improvements, and protects the value of our investments in both transportation infrastructure and adjacent land development. It is important that functionality be considered and in all stages of a highways lifecycle. This report provides guidance on how to protect, preserve, and enhance highway functionality within the areas of planning and land development, operations and capacity, right of way, infrastructure and maintenance, and safety. Each of the five areas plays a part in establishing how well or poorly a highway may function and in meeting or preserving its intended function. The project includes case studies of the IH 10 Katy Freeway in Houston, SH 289 in Frisco and Plano, and SH 105 between the cities of Conroe and Montgomery, Texas. These case studies show how functionality changes over time and identifies opportunities to preserve or restore functionality. The report provides recommendations for how TxDOT, MPOs, local jurisdictions, and other transportation stakeholders and agencies can protect, preserve, and enhance the functionality of the state highway system in Texas. It represents report R1 of TxDOT research project 0-6208, Preserving Functionality/Asset Value of the State Highway System.
