This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, sets out requirements for travel time reliability within a performance-based planning process. The research includes an effort to determine the economic value of improvements in travel time reliability by applying options theory from the financial sector. The report includes two succinct tables that describe requirements for person and freight trips for reliable transport, as well as a forecast of the year 2030 under alternative assumptions that may influence travel time reliability.

This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, provides a “how-to” guide for technical staff to select and calculate the appropriate performance measures to support the development of key planning products, including long-range transportation plans, transportation programs, congestion management process, corridor planning, and operations planning.

TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-L01-RR-2: Guide to Integrating Business Processes to Improve Travel Time Reliability explores various ways that transportation agencies could reengineer their day-to-day business practices to enhance traffic operations, address nonrecurring traffic congestion, and improve the reliability of travel times delivered to roadway system users.

This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, defines reliability and describes the research to improve the reliability of highway travel times by mitigating the effects of events that cause unpredictable, fluctuating travel times.

The 2005 Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users authorized the Dept. of Transportation (DoT) to establish a highway research program to address future challenges facing the U.S. highway system. In 2006, the Second Strategic Highway Research Program was established to conduct research in four areas -- safety, renewal, reliability, and capacity. The legislation also required a review of the program no later than three years after the first research contracts were awarded. This report provides information about the process for selecting the program's projects for funding, the projects' status, and what, if any, research was eliminated because of funding and time constraints. Charts and tables.

This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, focuses on geometric design treatments that can be used to reduce delays due to nonrecurrent congestion.

TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-L06-RR-1: Institutional Architectures to Improve Systems Operations and Management examines a large number of topics concerning organizational and institutional approaches that might help transportation agencies enhance highway operations and travel time reliability.
