Application of Travel Time Data and Statistics to Travel Time Reliability Analyses Report and Fact Sheet
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.
