A webinar presentation on project L03 processes and findings.

This presentation by Project L03 Principal Investigator Richard Margiotta to ITS Georgia on October 5, 2009 provides an overview of defining, measuring, and predicting reliability. The presentation ties into Project L03, which was ongoing at the time.

This diagram corresponds to Figure ES.2. in the SHRP2 report titled "Analytical Procedures for Determining the Impacts of Reliability Mitigation Strategies". It illustrates how several data sources came together as part of the SHRP2-L03 project. The Archive includes this very large L03 data set,

This handbook, titled "Handbook for Communicating Travel Time Reliability Through Graphics and Tables", offers numerous ideas on how to communicate reliability information in graphical and tabular form.

It describes the display options listed in Table 1 in page 4. The table shows the au

As part of the SHRP 2 program, project L02 focuses on measuring, monitoring, and recording travel time reliability (TTR) information. Through its guidebook, case studies, and demonstration software the project will help operating agencies develop systems – hardware, software, and strategies – tha

Within the second Strategic Highway Research Program (SHRP 2), Project L02 focused on creating a suite of methods by which transportation agencies could monitor and evaluate travel time reliability. Creation of the methods also produced an improved understanding of why and how travel times vary a
