A Particle Swarm Optimization Framework for Calibration of Driver Behavior Models at a Work Zone
Traffic impact assessment is a key step in the process of work zone planning and scheduling for transportation agencies. Microscopic traffic simulation models enable transportation agencies to conduct … [Read more...] about A Particle Swarm Optimization Framework for Calibration of Driver Behavior Models at a Work Zone
Feasibility of Lane Closures Using Probe Data
To develop an adequate traffic operations management and congestion mitigation plan for every roadway maintenance and construction project requiring lane closures, transportation agencies need … [Read more...] about Feasibility of Lane Closures Using Probe Data
Large Truck Safety in Work Zones
Work zones can create special challenges for drivers of large vehicles, such as commercial motor vehicles, due to space restrictions. Road work must take place within highway rights-of-way and, often, … [Read more...] about Large Truck Safety in Work Zones
Modeling Freeway Work Zones with Mesoscopic Dynamic Traffic Simulator: Validation, Gaps, and Guidance
This study developed a validation procedure for a dynamic traffic assignment—based mesoscopic simulator and identified its relevant data requirements. Model inconsistencies at the network level can be … [Read more...] about Modeling Freeway Work Zones with Mesoscopic Dynamic Traffic Simulator: Validation, Gaps, and Guidance
