Guide to 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. The research guide provides a detailed introduction to the business process mapping tool.

America’s highway system is critical to meeting the mobility and economic needs of local communities, regions, and the nation. Developments in research and technology—such as advanced materials, communications technology, new data collection technologies, and human factors science—offer a new opportunity to improve the safety and reliability of this important national resource.
