Abstract:
A traffic control device (TCD) is described for managing control of multiple right of way passages at a traffic intersection. The TCD includes a mobile wireless interface for communicating with an in-vehicle mobile wireless device (IV-MWD) to receive a commuter profile (CP) containing a subscribed switch time interval (SSTI). The TCD determines a set of passage priority values for respective ones of a set of controlled right of way passages. The TCD selects, based upon the set of passage priority values, a highest priority one of the set of controlled right of way passages as a next controlled right of way passage granted passage. The TCD resets a timer duration value associated with a next controlled right of way passage period, executes a right of way passage switch. Thereafter, the TCD maintains a current switch status of the traffic control device for a period corresponding to the timer duration value.
