TRB’s second Strategic Highway Research Program (SHRP 2) Reliability Project L05 has released a prepublication, non-edited version of a final report titled Incorporating Reliability Performance Measures into the Transportation Planning and Programming Processes that reviews domestic and international literature describing current research and practical use of travel-time reliability in transportation planning; summarizes results from a survey of state departments of transportation and metropolitan planning organizations about the current state-of-the-practice of using travel-time reliability in transportation planning; summarizes case studies of agencies that are incorporating reliability into their transportation planning processes; summarizes travel-time reliability performance measures, strategies for improving travel-time reliability, and tools for measuring the impacts of strategies on travel-time reliability; and describes the framework for incorporating reliability performance into the transportation planning process. The Final Report is designed to accompany the Technical Reference (http://www.trb.org/Main/Blurbs/168856.aspx) that provides a “how-to” guide for technical staff to select and calculate the appropriate performance measures to support the development of key planning products and a Guide (http://www.trb.org/Main/Blurbs/168855.aspx) designed to help planning, programming, and operations managers apply the concept of travel-time reliability to balance investment in programs and projects.
