Integrating Business Processes To Improve Travel Time Reliability

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.

"Addresses various ways that transportation agencies can 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"--Foreword.

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.

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, is designed to help planning, programming, and operations managers apply the concept of travel time reliability to balance investment in programs and projects.

TRB's second Strategic Highway Research Program (SHRP 2) Report S2-L06-RR-2 Guide to Improving Capability for Systems Operations and Management examines the way transportation agencies should be organized to successfully execute operations programs that improve travel time reliability. After the guide was submitted for publication, the American Association of State Highway and Transportation Officials (AASHTO) converted the SHRP 2 Reliability Project L06 research into a web-based tool that is designed to be user-friendly, easy to access, and updatable. The web tool, Systems Operations and Management Guidance, is available on the AASHTO website at http://www.aashtosomguidance.org.

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.
