System and method for utilizing traffic signal information for improving fuel economy and reducing trip time
First Claim
1. A method for determining a velocity for a vehicle traveling through a plurality of traffic signals, the method comprising:
- receiving first traffic signal data associated with a first traffic signal;
receiving second traffic signal data associated with a second traffic signal;
receiving position information associated with the vehicle, the position information comprising current location information for the vehicle; and
determining a reference velocity for traveling through the first and second traffic signal without having to stop at a red signal;
wherein the reference velocity is determined based at least in part on the first traffic signal data and the second traffic signal data.

Abstract
A system and method for utilizing traffic signal information to reduce wait time at traffic signals and to reduce fuel use is disclosed. Traffic signal timing data can be received from traffic signals or from a central server to determine a reference velocity for a vehicle to travel through a plurality of traffic signals. The reference velocity can then be provided to the driver so that the driver can manually control the vehicle at a velocity close to the reference velocity. The techniques of the present disclosure also can be used in connection with a cruise control system to control the velocity of a vehicle to be close to the reference velocity.
