Work Zone Capacity

A Platoon Regulation Algorithm to Improve the Traffic Performance of Highway Work Zones

This paper presents a cooperative traffic control strategy to increase the capacity of nonrecurrent bottlenecks such as work zones by making full use of the spatial resources upstream of work zones. … [Read more...] about A Platoon Regulation Algorithm to Improve the Traffic Performance of Highway Work Zones

Review of Methods for Estimating Construction Work Zone Capacity

Road reconstruction and the resulting work zones are considered as a major source of traffic congestion and delays on freeways. The roadway capacity is decreased as a result of a reduced number of … [Read more...] about Review of Methods for Estimating Construction Work Zone Capacity

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

Traffic Organization Scheme Design of Freeway Work Zone

With the development of the economy, some freeways have been overloaded by vehicles and need to be reconstructed or expanded. In addition, some freeways have been damaged and maintenance work is … [Read more...] about Traffic Organization Scheme Design of Freeway Work Zone

Deterministic and Stochastic Capacity in Work Zones: Findings From a Long-Term Work Zone

This paper describes the development of a breakdown probability model for a long-term work zone in a suburban area. It was found that the Gompertz distribution best describes the breakdown probability … [Read more...] about Deterministic and Stochastic Capacity in Work Zones: Findings From a Long-Term Work Zone

Development of Breakdown Probability Models and Heavy Vehicle Passenger Car Equivalents for Rural Freeway Work Zones

With nearly nine million lane-miles of public roadway and an economy driven by the automobile, interruptions to normal traffic operations for construction and maintenance are inevitable in the U.S.A., … [Read more...] about Development of Breakdown Probability Models and Heavy Vehicle Passenger Car Equivalents for Rural Freeway Work Zones
