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
