Systems and methods for traffic control
First Claim
1. A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- receiving, from an emergency communications network, an identifying credential for an emergency vehicle;
receiving, from the emergency communications network, routing information for the emergency vehicle, wherein the routing information indicates a route the emergency vehicle will proceed in;
determining one or more traffic signals the emergency vehicle will pass through in the received route;
generating one or more traffic signal time-bounded intersection tickets, wherein one traffic signal time-bounded intersection ticket is generated for each of the one or more traffic signals the emergency vehicle will pass through and wherein each traffic signal time-bounded intersection ticket comprises a predetermined valid time period;
generating an emergency vehicle time-bounded intersection ticket;
transmitting each of the one or more traffic signal time-bounded intersection tickets to the corresponding one or more traffic signals the emergency vehicle will pass through;
transmitting the identifying credential for the emergency vehicle to the one or more traffic signals the emergency vehicle will pass through; and
transmitting the emergency vehicle time-bounded intersection ticket to the emergency vehicle.

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.

5. A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
-
receiving, from a dispatch server, a time-bounded intersection ticket, wherein the time-bounded intersection ticket comprises a predetermined valid time period; receiving, from the dispatch server, a first identifying credential for an emergency vehicle; receiving, from the emergency vehicle, an encrypted traffic light control message; decrypting the traffic light control message with a key associated with the time-bounded intersection ticket; and determining, based at least in part on an evaluation of the contents of the traffic light control message if the traffic light control message is a valid request to provide expedited access at a traffic signal for the emergency vehicle. - View Dependent Claims (6, 7, 8, 9, 10)

11. A system, comprising:
-
at least one memory that stores computer-executable instructions; at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to; receive, from an emergency communications network, an identifying credential for an emergency vehicle; receive, from the emergency communications network, routing information for the emergency vehicle, wherein the routing information indicates a route the emergency vehicle will proceed in; determine one or more traffic signals the emergency vehicle will pass through in the received route; generate one or more traffic signal time-bounded intersection tickets, wherein one traffic signal time-bounded intersection ticket is generated for each of the one or more traffic signals the emergency vehicle will pass through and wherein each traffic signal time-bounded intersection ticket comprises a predetermined valid time period; generate an emergency vehicle time-bounded intersection ticket; direct communication of each of the one or more traffic signal time-bounded intersection tickets to the corresponding one or more traffic signals the emergency vehicle will pass through; direct communication of the identifying credential for the emergency vehicle to the one or more traffic signals the emergency vehicle will pass through; and direct communication of the emergency vehicle time-bounded intersection ticket to the emergency vehicle. - View Dependent Claims (12, 13, 14)
