Exploring simulation based dynamic traffic assignment with a large-scale microscopic traffic simulation model

This paper test the implementation of DTA in a commercial tool on a large-scale microscopic model, and results reveal why current DTA techniques may struggle and suggest mitigating.

Route Change Decision Making by Hurricane Evacuees Facing Congestion

Successful evacuations of metropolitan areas require overcoming unexpected congestion that reduces traffic flows. Congestion may result from accidents, incidents, or other events that reduce road…

Evacuee Route Choice Decisions in a Dynamic Hurricane Evacuation Context

Very high traffic volumes may lead to extensive congestion during hurricane evacuations. Evacuation planners reduce this congestion by careful planning for multiple hurricane scenarios and assignment…

All Accidents are Not Equal: Using Geographically Weighted Regressions Models to Assess and Forecast Accident Impacts

Transportation professionals have long recognized the importance of accounting for accident and incident impacts when designing and constructing transportation networks. Studies have used statistical…

Calibration of BPR Function Based on Link Counts and Its Sensitivity to Varying Demand

A previously developed genetic algorithm is used to find the best VDF parameters for a given demand level and then uses those parameters for varying demands and compares the results with associated synthetic vehicle counts, showing that VDFs calibrated to higher demand generally perform better in varying demands than those calibrated in lower demand scenarios.

Impact of Optimally Minimizing Delay Times on Safety at Signalized Intersections in Urban Areas, Case Study: The City of Virginia Beach

Optimally minimizing delay times at signalized intersections can significantly improve both traffic flow and safety. However, most traffic flow optimizing tools do not measure the effect on safety.…

Simulation analysis for evacuation under congested traffic scenarios: a case study

A new updated cell transmission model using discrete-event simulation, which can review and analyze the preferred path of evacuation traffic from multiple starting locations (or originations) to multiple destinations is introduced, which is capable of decreasing total travel time during an evacuation by thousands of vehicle hours.
