Risk to Workers or Vehicle Damage: What Makes Drivers Slow Down in Work Zones?
Objective Speeding in work zones is common and poses significant safety hazards to motorists and workers. Previous studies have demonstrated that speeding is reduced when workers are visible to the … [Read more...] about Risk to Workers or Vehicle Damage: What Makes Drivers Slow Down in Work Zones?
Spatial-Temporal Varying Coefficient Model for Lane-Changing Behavior in Work Zone Merging Areas
This study investigates the lane-changing behavior in work zone merging areas during the period from the time of starting a lane-changing maneuver to that of completing the lane-changing maneuver. … [Read more...] about Spatial-Temporal Varying Coefficient Model for Lane-Changing Behavior in Work Zone Merging Areas
Safety Analysis of Coordinated Warning Information in Construction Area of Expressway
Construction areas can easily cause traffic accidents and form traffic bottlenecks. In this study, based on driving simulation technology, a test platform for warning information of vehicle-road … [Read more...] about Safety Analysis of Coordinated Warning Information in Construction Area of Expressway
A Generic Work Zone Evaluation Tool Driven by a Macroscopic Traffic Simulation Model
This study proposed a generic work zone evaluation tool driven by a dynamic macroscopic traffic model. The tool can investigate the effects of a work zone on freeway conditions. The classical freeway … [Read more...] about A Generic Work Zone Evaluation Tool Driven by a Macroscopic Traffic Simulation Model
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
