Travel time reliability monitoring programs can help transportation agencies-especially those with transportation management centers-monitor the performance of their system, understand the impacts of the various influencing factors, provide credible information to the system users about what travel time reliability to expect, and decide what actions to take to help improve reliability. SHRP 2 Project L02 (Establishing Monitoring Programs for Mobility and Travel Time Reliability) created a suite of methods to help transportation agencies monitor and evaluate travel time reliability. The final report (http://www.trb.org/Main/Blurbs/168765.aspx) provides a brief narrative about what reliability is and how it can be measured and analyzed. The project also produced a guidebook (http://www.trb.org/Main/Blurbs/168764.aspx), which describes how an agency can develop and use a travel time reliability monitoring system. (Author/publisher)
