1.2.7.14: Manage Connected Signal Priority and Preemption Requests
This process shall receive indicator (e.g., signal) priority or preemption requests from other functions within ITS. These requests shall be collected and passed on to signal controller functions to give selected vehicles (e.g., those that belong to Emergency services, Transit Authorities, maintenance, and commercial vehicles) signal preemption/priority at intersections, pedestrian crossings, and multimodal crossings in the freeways, surface streets and rural roadways served by the Manage Traffic function. Sending of the request output shall also generate an output to the monitoring process to suspend its activities while the request is being served. An output indicating priority/preemption has been granted shall be sent to another process to help that process determine whether a fault detected at the signal is a true malfunction or due to a signal override. Fault indicators shall be sent to the Collect Traffic Field Equipment Fault Data.
This process is associated with the Connected Vehicle Roadside Equipment physical object.
