Optimizing Work Zone Schedules Considering Traffic Diversion With Artificial Bee Colony Algorithm
Highway maintenance activities often decrease roadway capacity and intrude traffic movements. The need to finish the project on time and under a specific budget while minimizing the traffic congestion … [Read more...] about Optimizing Work Zone Schedules Considering Traffic Diversion With Artificial Bee Colony Algorithm
Feasibility Analysis of COVID-19 Response Guidelines at Construction Sites in South Korea Using CYCLONE in Terms of Cost and Time
The emergence of the coronavirus disease 2019 (COVID-19) pandemic has led to a cost and time crisis for most construction projects around the world. Adherence to COVID-19 response guidelines for … [Read more...] about Feasibility Analysis of COVID-19 Response Guidelines at Construction Sites in South Korea Using CYCLONE in Terms of Cost and Time
How Does the Value of Time Influence Road User Costs During Work Zone Closures? A Case Study in El Paso, Texas, Using Simulation-Based Modeling Methods
It is becoming standard practice for many departments of transportation (DOTs) to use incentive/disincentive clauses (also known as road user costs) with contractors to stay on or ahead of schedule. … [Read more...] about How Does the Value of Time Influence Road User Costs During Work Zone Closures? A Case Study in El Paso, Texas, Using Simulation-Based Modeling Methods
Estimation of Road User Costs for Work Zones in Data-Limited or Time-Constrained Environments
This paper considers the problem of estimating road user costs (RUCs), such as travel time and delays, for roadway construction projects under time and data limitations. RUCs measure the mobility … [Read more...] about Estimation of Road User Costs for Work Zones in Data-Limited or Time-Constrained Environments
The National Performance Management Research Data Set (NPMRDS) and Application for Work Zone Performance Measurement
Transportation agencies are increasingly using probe vehicle data for transportation system performance management and as a resource for meeting the federal requirements of monitoring and reporting … [Read more...] about The National Performance Management Research Data Set (NPMRDS) and Application for Work Zone Performance Measurement
