Quantitatively Evaluate Work Zone Driver Behavior Using 2D Imaging, 3D LiDAR, and Artificial Intelligence in Support of Congestion Mitigation Model Calibration and Validation

This project addressed the following: 1) a lack of a system to process raw traffic footage obtained from work zones to extract traffic and driver behavior information, especially systems that leverage … [Read more...] about Quantitatively Evaluate Work Zone Driver Behavior Using 2D Imaging, 3D LiDAR, and Artificial Intelligence in Support of Congestion Mitigation Model Calibration and Validation

Trajectory Optimization of CAVs in Freeway Work Zone Considering Car-Following Behaviors Using Online Multiagent Reinforcement Learning

Work zone areas are frequent congested sections considered as the freeway bottleneck. Connected and autonomous vehicle (CAV) trajectory optimization can improve the operating efficiency in bottleneck … [Read more...] about Trajectory Optimization of CAVs in Freeway Work Zone Considering Car-Following Behaviors Using Online Multiagent Reinforcement Learning

Integrated Control Method for Ramp Traffic Flow in Construction Area of Expressway

In order to alleviate the traffic congestion of the expressway construction section without interrupting the traffic, an integrated control method of ramp traffic flow was proposed. Based on METANET … [Read more...] about Integrated Control Method for Ramp Traffic Flow in Construction Area of Expressway

Methodology for Applying Connected Vehicle Data to Evaluate Impact of Interstate Construction Work Zone Diversions

Diversion of Interstate traffic can significantly impact the surrounding road network with increased volumes and congestion. This paper uses commercially available connected vehicle data to examine … [Read more...] about Methodology for Applying Connected Vehicle Data to Evaluate Impact of Interstate Construction Work Zone Diversions

Characterizing Interstate Crash Rates Based on Traffic Congestion Using Probe Vehicle Data

Crash reduction factors are widely used by engineers for prioritizing safety investments. Work zones are routinely analyzed by the length and duration of queues. Queue detection warning technology has … [Read more...] about Characterizing Interstate Crash Rates Based on Traffic Congestion Using Probe Vehicle Data

Continued Updating the Lane Closure Guide for Urban Highways in the Kansas City, Kansas, Metropolitan Area

Temporary work zones in the United States continue to be an important and necessary aspect of preserving, expanding, and maintaining the roadway infrastructure network. However, work zones present a … [Read more...] about Continued Updating the Lane Closure Guide for Urban Highways in the Kansas City, Kansas, Metropolitan Area
