Efficient operations of traffic signals are of critical importance in urban areas, as signalized
intersections prevent the smooth flow of traffic and cause delays. This paper devises an eco …

Research on using high-resolution event-based data for traffic modeling and control is still at
early stage. In this paper, we provide a comprehensive overview on what has been …

Operations-oriented traffic signal performance measures are important for identifying the
need for retiming to improve traffic signal operations. Currently, most traffic signal …

Recently, high-resolution data has emerged as an economical means of obtaining detailed
information about signal operations. This has enabled the development of metrics to …

This paper formulates a simplified traffic smoothing model for guiding movements of
connected automated vehicles on a general one-lane highway segment. Adapted from the …

Intersections are among the most dangerous roadway facilities due to the existence of
complex movements of traffic. Most of the previous intersection safety studies are conducted …

Through wireless communications, enriched information from connected vehicles (CVs) can
describe traffic information near an intersection and would supplement a data source for an …

Signal offset optimization recently has been shown to be feasible with vehicle trajectory data
at low levels of market penetration. Offset optimization was performed on two corridors with …

During the past decade, there were a variety of probe vehicle data sources receiving
widespread deployment, ranging from roadside Bluetooth and Wi-Fi sensors to …

Performance measures offer an essential management tool for transportation engineers to
make decisions along signalized corridors. Current signal performance strategies assess …
