Evaluation of Green Lights on TMAs
The use of green versus traditional amber lights on Truck Mounted Attenuators (TMAs) was investigated to see if their use could help to improve safety in mobile work zones. Four light color … [Read more...] about Evaluation of Green Lights on TMAs
Exploring the Effects of the Location of the Lane-End Sign and Traffic Volume on Multistage Lane-Changing Behaviors in Work Zone Areas: A Driving Simulator-Based Study
The lane-changing behavior in work zone areas has special features than a regular lane change as the former is usually compulsively motivated involving complicated cognitive processes with drivers’ … [Read more...] about Exploring the Effects of the Location of the Lane-End Sign and Traffic Volume on Multistage Lane-Changing Behaviors in Work Zone Areas: A Driving Simulator-Based Study
Transportation Maintenance Operations Workforce Development: Challenges, Opportunities, and Solutions
