The USDOT's Intelligent Transportation Systems (ITS) Professional Capacity Building program will host a free webinar, ‘Variable Speed Limits: Are They for Everyone?’ on Tuesday, 4 April from 1300 to 1430. The webinar will be hosted by Jimmy Chu, a transportation specialist for the 831 Federal Highway Administration's Traveller Information Management Team.
Variable speed limit (VSL) systems use information on traffic speed, occupancy, volume detection, weather, and road surface condition to determine appropriate speeds that drivers should travel given current roadway and traffic conditions. The use of VSL during less than ideal conditions can improve safety by decreasing the risks associated with travelling at speeds that are higher than appropriate for the conditions and by reducing speed variance in traffic. In addition, VSL can be used to dynamically manage speeds during planned and unplanned events. In conjunction with managed lanes and other active traffic management strategies, VSL can help respond to downstream congestion to eliminate or delay bottlenecks and mitigate the possibility of crashes.
Attendees of this webinar can expect to learn about: Real-world examples of existing, deactivated, and planned VSL systems in the United States and other parts of the world and the state of the practice of VSL operations. The webinar will also cover successful and best practices from perspectives such as planning, policy, design, deployment, standards, operations, maintenance and outcomes.
