This project presents a review on reliability
performance measures, selection of reliability performance measures for
analysis, gathering perceptions of North Carolina road users on reliability,
analysis of data collection and the value of travel time measures and
reliability to evaluate the impact of transportation alternatives. The average
travel time is correlated to most travel time and travel time percentile based
measures. It can be used to assess travel time savings – before-after
comparison or selection between projects.
Quantifying and using these measures to assess the impact of
transportation projects / alternatives eases further with advancements in
technology and availability of rich travel time datasets.
