The operation of traffic signals is currently limited by the data available from traditional point
sensors. Point detectors can provide only limited vehicle information at a fixed location. The …

Traffic signals at intersections are an integral component of the existing transportation
system and can significantly contribute to vehicular delay along urban streets. The current …

This paper presents two algorithms to estimate traffic state in urban street networks with a
mixed traffic stream of connected and unconnected vehicles and incorporates them in a real …

The connected vehicle research initiative is the core of the US Department of
Transportation's intelligent transportation system research program. The initiative is …

A unified platoon-based mathematical formulation called PAMSCOD is presented to perform
arterial (network) traffic signal control while considering multiple travel modes in a vehicle-to …

We study the traffic signal control problem with connected vehicles by assuming a fixed
cycle length so that the proposed model can be extended readily for the coordination of …

With the development of modern wireless communication technology, especially the vehicle
infrastructure integration (VII) technology, vehicles' information such as identification …

This paper develops estimators for market penetration level and arrival rate in finding queue
lengths from probe vehicles at isolated traffic intersections. Closed-form analytical …

In this paper, we present an adaptive signal control scheme to prevent intersection traffic
blockage resulted from vehicle queue spillover. A method to identify vehicle queue spillover …

Queue spillbacks are a major problem in urban signalized arterials because such spillbacks
can lead to gridlock and excessive delays. Several methods based on fixed-location …
