Title: SYSTEMS AND METHODS FOR TRAFFIC CONTROL
Abstract:
Systems and methods for real-time emergency vehicle authentication at traffic signal and tollgates are disclosed. In certain example embodiments, a dispatch server can provide identifying credentials and time-bounded intersection tickets (TBIT) to traffic signals and tollgates for conducting authentication of emergency vehicles. The emergency vehicles can transmit a traffic light control message requesting expedited access through a traffic signal or tollgate. The traffic signal or tollgate can decrypt the message using the TBIT. It can further determine if the identifying credential received from the emergency vehicle is authorized for expedited access and if the message was received within a required time period. In response, the traffic signal or tollgate can determine its current signal or gate position and determine if a change needs to be made to provide expedited access to the emergency vehicle.
