Analysis of Injury Severity of Large Truck Crashes in Work Zones
Work zones are critical parts of the transportation infrastructure renewal process consisting of rehabilitation of roadways, maintenance, and utility work. Given the specific nature of a work zone … [Read more...] about Analysis of Injury Severity of Large Truck Crashes in Work Zones
Improving the Effectiveness of Smart Work Zone Technologies
This project evaluates the effectiveness of sensor network systems for work zone traffic estimation. The comparative analysis is performed on a work zone modeled in microsimulation and calibrated with … [Read more...] about Improving the Effectiveness of Smart Work Zone Technologies
Artificial Neural Network Model for Estimating Temporal and Spatial Freeway Work Zone Delay Using Probe-Vehicle Data
Highway lane closures due to road reconstruction and the resulting work zones have been a major source of nonrecurring congestion on freeways. It is extremely important to calculate the safety and … [Read more...] about Artificial Neural Network Model for Estimating Temporal and Spatial Freeway Work Zone Delay Using Probe-Vehicle Data
Model Development for Use of Portable Traffic Signals in Conjunction with Pilot Car Operations at Two-Lane, Two-Way Rural Highway Work Zones
A portable traffic signal (PTS) system is a traffic control device designed to facilitate the movement of one-way traffic at work zones where there is a temporary lane closure. The 2009 edition of the … [Read more...] about Model Development for Use of Portable Traffic Signals in Conjunction with Pilot Car Operations at Two-Lane, Two-Way Rural Highway Work Zones
What Role Do Precrash Driver Actions Play in Work Zone Crashes?: Application of Hierarchical Models to Crash Data
Highway infrastructure requires periodic maintenance, reconstruction, and rehabilitation. As a result, highway users have to deal with work zone activities such as lane closures and lane shifts or … [Read more...] about What Role Do Precrash Driver Actions Play in Work Zone Crashes?: Application of Hierarchical Models to Crash Data
