Guide to Establishing Monitoring Programs for Travel Time Reliability


The SHRP2 L02 project is being carried out to “develop system designs for programs to monitor travel time reliability and to prepare a guidebook that practitioners and others can use to design, build, operate, and maintain such systems.” The Guidebook is intended to help agency staff identify functionalities they would like in a monitoring system or to learn new functionalities that can be implemented using a current system. The guidebook provides guidance about the data collection, data management, computational engine, and management of a travel time reliability monitoring system.
