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
An Optimization Methodology to Improve Work Zone Safety Within a Limited Budget in a Roadway Network
In the U.S., total 94,000 crashes (Fatal 710, Injury 36,290, and PDO 57,000) occurred in work zones in 2017. The economic cost to these crashes is estimated at nearly $17.5 billion. Data revealed that … [Read more...] about An Optimization Methodology to Improve Work Zone Safety Within a Limited Budget in a Roadway Network
