Signal retiming is a prominent way that transportation agencies use to fight congestion and
change of traffic pattern. Performance evaluations of traffic conditions at signalized …

Traffic light optimization is known to be a cost-effective method for reducing congestion and
energy consumption in urban areas without changing physical road infrastructure. However …

Many agencies use Automated Traffic Signal Performance Measures (ATSPMs), which
require vehicle detection and communication equipment, to evaluate traffic signal efficiency …

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 …

Advances and cost reductions in Light Detection and Ranging (LiDAR) sensor technology
have allowed for their implementation in detecting vehicles, cyclists, and pedestrians at …

Evaluating arterial operational performance plays a pivotal role in arterial system
management and enhancement. As a fundamental reference guide for traffic engineers, the …

Automatically generating performance measures for signalized intersections is important for
agencies to assess how individual movements perform at various intersections. This …

Split failures have been a conventional method to estimate overcapacity at signalized
intersections. Currently, split failures are estimated from high-resolution (HR) traffic signal …

Connected vehicle data have the potential to warn motorists of impending slowdowns and
congestion in real time. Multiple data providers have recently begun providing in-cab alerts …

Adaptive traffic control systems (ATCSs) represent one of the most advanced traffic signal
control strategies currently deployed in urban areas worldwide. One of the most important …
