In recent years, there has been a growing desire for the use of probe vehicle technology for
congestion detection and general infrastructure performance assessment. Unlike costly …

Connected vehicle (CV) data have the potential to transform traffic signal operations, but the
success of control methods that are based on CV data depends on the level of market …

This paper discusses low-cost approaches capable of ranking traffic intersections for the
purpose of signal re-timing. We extracted intersections that are comprised of multiple roads …

Performance measures are essential for managing transportation systems and
demonstrating agency accountability. Probe vehicles are an effective means for gathering …

The primary purpose of this study is to develop a systematic approach to effectively
identifying and ranking recurrent freeway bottlenecks using travel-time reliability (TTR) …

Commercial Vehicles crossing the international land port of entries (LPOEs) go through
multiple screenings/stops contributing to the long queues at the congested border crossings …

The Moving Ahead for Progress in the 21st Century Act (MAP-21) mandates that state
departments of transportation monitor and report performance measures in several areas …

This study applies and updates a method which identifies and quantifies the extent of traffic
congestion from recurring freeway bottlenecks. Additionally, the spatiotemporal stability of …

Probe-based speed data provide great value to agencies; especially, in areas which are not
feasibly covered by traffic sensors. However, as with sensors, probe data are not without …

There are multiple vendors that now provide real-time probe data based interstate speed
measurements at sub-1 mile, 1-min fidelity. This paper presents an analytical tool for …
