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

Research on Deceleration Behavior Characteristics of Highway Reconstruction and Extension Work Zone

To study the relationship between deceleration and facility setting mode of expressway reconstruction areas, independent variables such as the number of traffic signs and the distance between … [Read more...] about Research on Deceleration Behavior Characteristics of Highway Reconstruction and Extension Work Zone

Improvement of Highway Work Zone Performance by Traffic Management

This study investigates the effects of traffic management strategies on performance of a work zone along arterial roads. The strategies included Temporary Access Control (TAC), Limitation of Heavy … [Read more...] about Improvement of Highway Work Zone Performance by Traffic Management

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

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

Study on the Length of Median Opening in Expressway Reconstruction and Extension Work Zones

The opening length and influencing factors were studied aiming at the traffic of the two lanes at median opening section in expressway reconstruction and extension work zones. Based on the analysis of … [Read more...] about Study on the Length of Median Opening in Expressway Reconstruction and Extension Work Zones
