TM13-San Diego Rail Crossing Notifications
Status: Existing
Description
This service package manages highway traffic at rail intersections where operational requirements do not dictate more advanced features (e.g., where rail operational speeds are less than 80 miles per hour). Includes bike and pedestrian crossing permissions. Both passive (e.g., the crossbuck sign) and active warning systems (e.g., flashing lights and gates) are supported. (Note that passive systems exercise only the single interface between the ITS Roadway Equipment and the Driver in the physical view.) These traditional warning systems may also be augmented with other standard traffic management devices. The warning systems are activated on notification of an approaching train by interfaced wayside equipment. The equipment may also be interconnected with adjacent signalized intersections so that local control can be adapted. Health monitoring of the equipment and interfaces is performed; detected abnormalities are reported to both roadway and railroad officials through wayside interfaces and interfaces to the Traffic Management Center.
