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
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

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 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.
A webinar presentation on project L03 processes and findings.
An overview of project L03's process and findings.
An at-a-glance overview of the L03 Project.
The fundamental objective of SHRP 2 Project L03 was to develop predictive relationships between highway improvements and travel time reliability. In other words, how can the effect of an improvement on reliability be predicted? Alternatively, how can reliability be characterized as a function of
The Trajectory Processor is an essential part of the analytical framework developed under the SHRP2 L04 project to produce travel time reliability performance measures from planning and simulation model outputs. It calculates and visualizes travel time distributions and ssociated reliability indi
