Roadway Variable Speed Limits

• The field element shall monitor and report faults to the controlling center.
• The field element shall collect operational status of the variable speed limit field equipment and report the operational status to the controlling center.
• The field element shall display additional information such as basic safety rules and current traffic information to drivers.
• The field element shall display the current speed limits per lane to drivers.
• The field element shall receive commands from the controlling center that establish speed limits by lane.
• The field element shall autonomously calculate and set variable speed limits based on current conditions by lane.
• The field element shall monitor traffic and environmental conditions along the roadway.

TMC Variable Speed Limits

• The center shall provide center personnel current system status and respond to control data from center personnel regarding variable speed limits and
• The center shall monitor the operational status of the variable speed limit equipment, including fault reports.
• The center shall control field equipment that posts the current speed limits and displays additional information such as basic safety rules and current traffic information to drivers.
• Based on the measured data, the center shall calculate and set suitable speed limits by lane.
• The center shall monitor data on traffic and environmental conditions collected from sensors along the roadway.
