Assessing Performance Potential of Signalized Intersections and Arterials

Speed and Delay on Signalized Arterials Speed and Delay on Signalized Arterials

This research presents a model to predict the influence of demand and capacity on the running speed of signalized arterials in Montgomery County, Maryland. The model separates the changes to link running speed due to same-direction traffic and intersection approach delay from cross traffic. It is found that flow has a small impact on link speed, each 1000 vehicles per lane per hour reduces spee...

Optimizing Signalized Intersections Performance under Conventional and Automated Vehicles Traffic

Automated vehicles, or AVs (i.e. those that have the ability to operate without a driver and can communicate with the infrastructure) may transform the transportation system. This study develops and simulates an algorithm that can optimize signal control simultaneously with the AV trajectories under undersaturated traffic flow of AV and conventional vehicles. This proposed Intelligent Intersect...

Anonymous Vehicle Tracking for Real-time Traffic Surveillance and Performance on Signalized Arterials

One of the fundamental requirements to facilitate implementation of any Advanced Transportation Management and Information System (ATMIS) is the development of a real-time traffic surveillance system to produce reliable and accurate traffic performance measures. This study presents a new framework for anonymous vehicle tracking that is capable of tracing individual vehicles by utilizing vehicle...
