The webinar will present how various federal agencies, FHWA, Federal Motor Carrier Safety Administration (FMCSA), and National Highway Traffic Safety Administration (NHTSA), are trying to increase safety and mobility for large trucks in work zones.  Each agency will provide an overview of their program’s initiatives to tackle this important issue.  Additionally, other stakeholders will highlight their local efforts in Iowa, Alabama, and Vermont to increase safety and mobility.  Iowa has deployed a vehicle entering warning (VEW) system that detects construction tractor-trailer units hauling materials out of the median of the work zone and alerts motorists when trucks are entering the highway.  In Vermont, the commercial vehicle enforcement section is working with other state agencies, private contractors and the motoring public to address work zone safety concerns in their state.  In Alabama, they are working on several projects for the Alabama Work Zone Notification System and this presentation will describe the goals, objectives, areas of concern and how they plan to measure user behavior.
