Improved Strategies For Deploying Vehicle-Actuated Control At Isolated Signalized Intersections, Michael J. Cassidy, Yu-Hao Chuang, Jeffrey Dunn Vitale Jan 1995

Improved Strategies For Deploying Vehicle-Actuated Control At Isolated Signalized Intersections, Michael J. Cassidy, Yu-Hao Chuang, Jeffrey Dunn Vitale

JTRP Technical Reports

This research has sought to demonstrate potential benefits from deploying enhanced vehicle actuation strategies at isolated signalized intersections. The work has exploited microscopic, stochastic simulation to evaluate impacts of enhanced vehicle-actuated (VA) control schemes for an array of operating conditions. Simulated outcomes (i.e. average vehicle delays) generated under the enhanced strategies were compared with outcomes resulting from more “conventional VA control policies. Findings from this work suggest that substantial delay reduction generally occurs by exploiting VA strategies which seek to 1) facilitate the use of the clearance interval by discharging vehicles, 2) shorten the duration of the required clearance interval …

Predicting Traffic Impacts At Two-Lane Highway Work Zones, Michael J. Cassidy, Youngtae Son Jan 1995

Predicting Traffic Impacts At Two-Lane Highway Work Zones, Michael J. Cassidy, Youngtae Son

JTRP Technical Reports

Maintenance or reconstruction activity on a two-lane highway often requires a lane closure. The implementation of “one-way traffic control,” required to maintain traffic flow throughout the work zone, typically produces significant motorist delay. This report describes the adaptation and application of queuing models, originally derived for intersections controlled by vehicle-actuated traffic signals, to estimate delay at two-lane highway work zones. The models estimate expected delay as a function of directional traffic demand rates, work zone physical length and observed traffic measures. Validation efforts using simulation suggest that the models accurately predict the impacts of two-lane highway lane closures.
