Traffic Flow

 

Real-Time Work Zone Traffic Management via Unmanned Air Vehicles

Highway work zones are prone to traffic accidents when congestion and queues develop. Vehicle queues expand at a rate of 1 mile every 2 minutes. Back-of-queue, rear-end crashes are the most common … [Read more...] about Real-Time Work Zone Traffic Management via Unmanned Air Vehicles

Integrated Control Method for Freeway Work Zones Under Partially Connected Vehicle Environment

Highway work zones can cause traffic congestion and even traffic accidents. Dynamic lane merging (DM) and variable speed limit (VSL) systems are possible solutions to improve the efficiency of work … [Read more...] about Integrated Control Method for Freeway Work Zones Under Partially Connected Vehicle Environment

Utah DOT Traffic App Tops One Million Downloads

The UDOT Traffic app, a smartphone traffic monitoring application launched by the Utah Department of Transportation in 2011, surpassed one million downloads in January 2021. The app serves as … [Read more...] about Utah DOT Traffic App Tops One Million Downloads

Simulation and Evaluation of Speed and Lane-Changing Advisory of CAVS at Work Zones in Heterogeneous Traffic Flow

Emerging connected autonomous vehicle (CAV) technologies provide an opportunity to the vehicle motion control to improve the traffic performance. This study simulated and evaluated the CAV-based speed … [Read more...] about Simulation and Evaluation of Speed and Lane-Changing Advisory of CAVS at Work Zones in Heterogeneous Traffic Flow

Modeling the Traffic Flow of the Urban Signalized Intersection With a Straddling Work Zone

Work zones widely exist on urban roads in many countries and have a significant negative impact on traffic. Few studies have focused on modeling the traffic flow of the work zone on the urban … [Read more...] about Modeling the Traffic Flow of the Urban Signalized Intersection With a Straddling Work Zone

The National Performance Management Research Data Set (NPMRDS) and Application for Work Zone Performance Measurement

Transportation agencies are increasingly using probe vehicle data for transportation system performance management and as a resource for meeting the federal requirements of monitoring and reporting … [Read more...] about The National Performance Management Research Data Set (NPMRDS) and Application for Work Zone Performance Measurement
