selected_emergency_vehicle_strategy

This data flow is used within the Manage Traffic function and contains the strategy which has been selected to enable preemption to be given to emergency vehicles through the road (surface street) and highway network controlled by the TMC. It will cover intersection controllers, pedestrian controllers, dynamic message signs (DMS) that control lane use and ramp metering controllers. The strategies for each of these individual types of unit will be sent out as the strategies to their individual control processes. The strategy may be applied to some or all of the units on the roads and highways in the geographic area served by the TMC. The data flow consists of the following data items each of which is defined in its own DDE:
