Performance Measurement

Modeling Highway Performance Under Various Short-Term Work Zone Configurations

Federal rules mandate state departments of transportation and metropolitan planning organizations to measure and report on the performance of highways within their jurisdictions. Those rules support … [Read more...] about Modeling Highway Performance Under Various Short-Term Work Zone Configurations

Effective Post Construction Evaluation Practices for Work Zone Management Strategies

State Departments of Transportation (DOTs) invest a significant amount of effort to develop and implement Transportation Management Plans (TMPs) in order to effectively manage the traffic flow of work … [Read more...] about Effective Post Construction Evaluation Practices for Work Zone Management Strategies

Validating the Performance of the FHWA Work Zone Model Version 1.0: A Case Study Along I-91 in Springfield, Massachusetts

Central to the effective design of work zones is being able to understand how drivers behave as they approach and enter a work zone area. States use simulation tools in modeling freeway work zones to … [Read more...] about Validating the Performance of the FHWA Work Zone Model Version 1.0: A Case Study Along I-91 in Springfield, Massachusetts

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
