This data flow is used within the Manage Traffic function and defines the special traffic control strategy needed to enable the passage of a commercial vehicle containing a special permitted load through the road (surface street) and highway network included in the vehicle's route. The control strategy may affect both intersection signal controllers and/or dynamic message signs (DMS) used for lane control, and/or ramp metering controllers used to regulate the entry of vehicles onto highways. The data flow consists of the following data items each of which is defined in its own DDE:
