First Claim
1. A for providing visual display of suggested speeds on a user device, the method comprising:
- receiving, at a system including one or more processors, a current location and a direction of travel from the user device in a vehicle;
receiving traffic signal information comprising a current status of a plurality of traffic signal devices;
determining an optimal speed profile for the vehicle based on the current location,the direction of travel, and the traffic signal information, the optimal speedprofile comprising a range of speeds required to pass through at least two consecutive traffic signal devices without stopping;
sending the optimal speed profile for the vehicle to the user device; and
displaying, on the user device, an indication of the optimal speed profile.

Abstract
A traffic routing display system provides a visual display of a speed or series of speeds suggested to the driver such that the driver may pass through multiple consecutive traffic signal devices without stopping at a red light. In one aspect, the display depicts the expected state of an upcoming traffic light. In another aspect, the display is an icon colored to correspond to the expected state. In another aspect, the time remaining before the state of a traffic light changes is displayed. The effect that an indicator has on driver behavior is used to determine the type of indicator to provide to the driver. Certain indicators may not be displayed by the system depending on the effect they have on the driver.
