Application of Travel Time Data and Statistics to Travel Time Reliability Analyses Report and Fact Sheet
Posted: 9/18/2023

The second Strategic Highway Research Program (SHRP2) funded project, "Application of Travel Time Data and Statistics to Travel Time Reliability Analyses," has been completed and a report and fact sheet detailing the results are now available. The intent of the report is twofold: to provide practitioners with the ability to understand the differences in reliability measures derived from the different data sources and to document the steps needed to turn high-resolution travel time data into reliability performance measures. The report covers several topics including: data sources for reliability; data processing methods for reliability; and creating and comparing reliability measures, highlighting differences and similarities in the use of data from different sources. A case study was conducted that compared reliability measures developed from different data sources using different processing methods. A four-page fact sheet was also developed.
