This data flow is a special form of route similar to an emergency vehicle route, but for use by other vehicle types which may be given special priority routing (e.g., traffic control preemption routing). This could be applied to HOV vehicles, special HAZMAT, priority vehicles (e.g., governors motorcade), or even to regular vehicles under a low traffic volume period (e.g., in the early hours of the morning). This flow contains the items shown below each of which is defined in its own DDE:
