Descripton

Variable Speed Limit (VSL) signs are a planned ITS element related to Ohio's Active Traffic and Demand Management (ATDM) program that aims to increase travel time reliability on Ohio DOT roadways in major metro areas. VSL signs in the field would communicate centrally with the Ohio Statewide TMC, and reduced speeds would be implemented either by TMC operators or would be automated based on the level of traffic detected by nearby Ohio DOT Vehicle Detection Devices.
