incident_overrides

This data flow is used within the Manage Traffic function to transfer changes in traffic control strategy and details of current incidents and planned events from the Manage Incidents facility to the Provide Device Control facility for implementation. The changes in strategy are of two types, one covering changes to road, and/or highway, and/or entry ramp control strategy and the other covering advisory message texts for output using dynamic message signs (DMS). The data flow consists of the following data items each of which is defined in its own DDE:

cv_incident_override
+ current_incident_static_data
+ planned_event_data_for_roadway_information
+ incident_strategy_override
+ roadway_information_incident_updates
+ roadway_info_alert_data
+ roadway_information_evacuation_data
