Patent Images
1. A traffic communication system, comprising:
- a traffic signal having a plurality of states;
a controller subsystem, remote from the traffic signal, configured to communicate with the traffic signal; and
a user device, remote from the controller subsystem, configured to communicate with the controller subsystem via a network, the user device further configured for communications with the traffic signal using the controller subsystem as an intermediary.

Abstract
A traffic routing system reduces emissions from commuter and other traffic, eases congestion on roadways, and decreases transit time by use of communications among vehicles and traffic controls, such as traffic lights. In one aspect, a traffic light receives a signal that a vehicle is approaching and in response turns green to allow the vehicle to pass without impairment. In another aspect, a vehicle receives a signal to adjust a current rate of speed to arrive when a traffic signal allows vehicles to pass. In still another aspect, a combination of congestion, emergency traffic, roadwork and similar factors influence proposed routes sent to vehicles.

8. A user device, comprising:
-
a non-transitory computer-readable storage medium storing executable computer program code for; sending to a controller, via a network, location information; receiving, via the network, information relating to a state of a traffic signal, the traffic signal being selected responsive to the location information; and a processor configured to communicate with the computer readable medium and to execute the program code.

9. A controller subsystem, comprising:
-
a non-transitory computer-readable storage medium storing executable computer program code for; receiving from a traffic signal information relating to states of the traffic signal, the traffic signal remote from the controller subsystem; and sending to a user device, via a network, an indication of a state of the traffic signal at a specified time, the indication based on the information; and a processor configured to communicate with the computer readable medium and to execute the program code. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A computer-implemented method of communicating information between a vehicle and a traffic signal, comprising:
-
operatively connecting the vehicle to a network by a user device; operatively connecting an interaction module to the network, the interaction module operatively connected to the traffic signal, wherein the traffic signal is remote from the interaction module; and communicating the information between the vehicle and the traffic signal using the interaction module as an intermediary. - View Dependent Claims (17, 18)
