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
Work Zone Safety Performance: Comparison of Alternative Traffic Control Strategies
Work zone temporary traffic control strategies generally affect both traffic safety and operations. However, there is a substantial gap in the knowledge base with respect to the safety impacts of … [Read more...] about Work Zone Safety Performance: Comparison of Alternative Traffic Control Strategies
Development of Rate-Based Statewide Safety Performance Measures of Work Zones Using Imperfect Exposure Data: A Virginia Case Study
Ideally, state departments of transportation would track work zone crashes over time while simultaneously accounting for traffic exposure using work zone vehicle miles of travel (VMT). Work zone VMT … [Read more...] about Development of Rate-Based Statewide Safety Performance Measures of Work Zones Using Imperfect Exposure Data: A Virginia Case Study
Work Zone Traffic Management Analysis Using Analytical Methods
The course provides hands-on training on basic analytical methods (sketch planning methods) to compute work zone performance measures (WZPM). The WZPM includes the following factors: capacity, speed, … [Read more...] about Work Zone Traffic Management Analysis Using Analytical Methods
Combining Safety Analysis Tools for Evaluation of Freeway Work Zones: A Case Study
Predictive methods are available in the Highway Safety Manual (HSM) to estimate the safety performance of various types of roadway facilities, including freeways. These methods were developed to … [Read more...] about Combining Safety Analysis Tools for Evaluation of Freeway Work Zones: A Case Study
