Optimizing Scheduling of Long-Term Highway Work Zone Projects
The impacts of work zone activities can be summarized into the following types: safety impact (on both motorists and workers), mobility impact, economic considerations, environmental concerns, user … [Read more...] about Optimizing Scheduling of Long-Term Highway Work Zone Projects
Safety Assessment Tool for Construction Zone Work Phasing Plans
The Highway Safety Manual (HSM) is the compilation of national safety research that provides quantitative methods for analyzing highway safety. The HSM presents crash modification functions related to … [Read more...] about Safety Assessment Tool for Construction Zone Work Phasing Plans
Work Zones Versus Nonwork Zones: Risk Factors Leading to Rear-End and Sideswipe Collisions
Tens of thousands of vehicular collisions occur annually in work zones with nearly double the fatality risk as compared to all collisions (work zone and nonwork zone). Due to this increase in risk, … [Read more...] about Work Zones Versus Nonwork Zones: Risk Factors Leading to Rear-End and Sideswipe Collisions
Evaluating the Effectiveness of Traffic Diversion and Managed Lanes on Highway Work Zones
Temporary work zones (TWZs) have become the second largest contributor to the non-recurring delay of U.S. highways, causing nearly 24 % of all non-recurring delay and 10 % of overall delay. Efficient … [Read more...] about Evaluating the Effectiveness of Traffic Diversion and Managed Lanes on Highway Work Zones
Innovative Work Zone Capacity Models from Nationwide Field and Archival Sources
Freeway work zone capacity has been the focus of significant research, but most studies were limited to specific geographic regions or work zone configurations or both. To date, no work zone … [Read more...] about Innovative Work Zone Capacity Models from Nationwide Field and Archival Sources
