Development of a Low-Cost Work Zone Queue Warning System
Back-of-queue crashes are a significant safety hazard in highway work zones—especially those with intermittent congestion. A number of intelligent transportation systems (ITS) have been developed to … [Read more...] about Development of a Low-Cost Work Zone Queue Warning System
Work Zone Data Management Applications and Opportunities
Highway work zones often have major safety and mobility impacts, which are made worse when travelers are unaware that they are approaching a work zone. To monitor and mitigate the mobility and safety … [Read more...] about Work Zone Data Management Applications and Opportunities
Rapid Response Techniques for Adverse Weather and Climate Events Affecting Work Zones
While 2020 will certainly be remembered for the Covid-19 pandemic, it was also a year of heavy damage from adverse weather and climate events. In the US, these included an unprecedented 22 events that … [Read more...] about Rapid Response Techniques for Adverse Weather and Climate Events Affecting Work Zones
Work Zone Driveway Assistance Devices (DADs): Past Research & Evaluation of Display Strategies
The Driveway Assistance Device (DAD) is an experimental device used to direct traffic onto a bi-directional, single-lane work zone from a driveway or side street. This device uses alternating flashing … [Read more...] about Work Zone Driveway Assistance Devices (DADs): Past Research & Evaluation of Display Strategies
Work Zone Crash Prediction Model and Characteristics Analysis
This research’s main goal is to improve the safety of work zones. It is commonly thought that work zones have a negative impact on the number of vehicle crashes. In addition to the high cost for … [Read more...] about Work Zone Crash Prediction Model and Characteristics Analysis
