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
Road User Costs for Highway Construction Projects Involving a Lane Closure
While for years most American State Highway Agencies have performed Road User Cost (RUC) calculations, no uniformity from state to state has been established. There is scant research available that … [Read more...] about Road User Costs for Highway Construction Projects Involving a Lane Closure
Probabilistic Methodology to Quantify User Delay Costs for Urban Arterial Work Zones
The total cost of road construction comprises direct costs paid by agencies and indirect costs paid by road users. In densely populated urban areas, work zone instigated user costs could outweigh … [Read more...] about Probabilistic Methodology to Quantify User Delay Costs for Urban Arterial Work Zones
Smart Work Zone (SWZ) Technical Concept Study: Phase No. 1: Final Draft Working Paper 1 – Nationwide Review of SWZ Technologies
As part of Arizona Department of Transportation’s (ADOT) Implementation Guidelines for Work Zone Safety and Mobility process review, ADOT is continually looking at ways to expand/enhance existing … [Read more...] about Smart Work Zone (SWZ) Technical Concept Study: Phase No. 1: Final Draft Working Paper 1 – Nationwide Review of SWZ Technologies
