1.2.7.14: Manage Local Signal Priority Requests

This process shall receive indicator (e.g., signal) priority requests from other functions within ITS. These requests shall enable the process to give selected vehicles (e.g., those that belong to Transit Authorities) signal 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 priority request output shall also generate an output to the monitoring process to suspend its activities while the priority request is being served. An output indicating priority 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.
