Physical Object: ITS Roadway Equipment
Roadway Variable Speed Limits
Overview
"Roadway Variable Speed Limits" includes the field equipment, physical overhead lane signs and associated control electronics that are used to manage and control variable speed limits systems. This equipment monitors traffic and environmental conditions along the roadway. The system can be centrally monitored and controlled by a traffic management center or it can be autonomous, calculating and setting suitable speed limits, usually by lane. This application displays the speed limits and additional information such as basic safety rules and current traffic information to drivers.
This application object is included in the "ITS Roadway Equipment" physical object.
