Traffic flow and travel time-based measures are used to quantify and characterize
congestion levels on urban roadway networks. However, under low-density conditions …

Increasing congestion levels and their elusive impact warrants the development of
congestion mitigation strategies. Quantifying congestion and analyzing the spatiotemporal …

With the expected increase in the availability of trajectory-level information from connected
and autonomous vehicles, issues of lane changing behavior that were difficult to assess with …

This study tests the hypothesis that an analytically estimated driver reaction time required for
asymptotic stability, based on the macroscopic Gazis-Herman-Rothery (GHR) model, serves …

Travel time reliability is considered one of the most important measures of the transportation
system performance that clearly conveys the operational characteristics of a roadway …

In this study, we assessed the state-of-the-practice methods of deploying incident
management strategies and investigated areas for improvement. We also developed a …

This project created tools, empowered by big data, that can identify in real-time the onset of
congestion and the occurrence of incidents, for both freeways and arterials. The target …

How to effectively identify traffic bottlenecks on the freeway and accordingly implement
targeted countermeasures remains a critical issue for traffic management and control. With …

In this study, sodium persulfate was encapsulated in polyvinyl acetate (PVAc) polymer to
investigate the potential of activated persulfate to remediate total coliform and E. coli …
