9.3.3.2 - Monitor Vehicle Speed in Work Zone
This process shall be responsible for monitoring the speeds of vehicles traveling in a work zone. The process shall receive inputs from devices that monitor the speed of individual vehicles as well as from devices that monitor the speed of the flow of traffic. The process shall be responsible for the control of the devices that monitor individual vehicle speed. The process shall receive an input from environmental sensors at the roadway. The process shall assess, using the environmental conditions as an input, whether speed in the work zone exceeds the speed limit, or is excessive given the environmental conditions. The process shall be capable of notifying the Enforcement Agency when vehicle speeds in the work zone are in excess of the posted speed limit or are creating an unsafe condition based upon the current environmental conditions. The process shall provide safe speed threshold parameters based on environmental conditions and vehicle characteristics to another process for determining whether driver safe speed advisories should be issued. The process shall receive an input from the speed enforcement process indicating speed violations that have been identified.
