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.

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; anddisplaying, on the user device, an indication of the optimal speed profile. 2. The method of claim 1, wherein displaying an indication of the optimal speed profile on the user device comprises dynamically displaying a traffic signal indicator for each traffic signal device of the at least two consecutive traffic signal devices, the traffic signal indicator indicating a current status of the traffic signal device. 3. The method of claim 1, wherein the range of speeds is capped at a maximum speed based on at least one of a speed limit at the current location of the user device in the vehicle and a current speed of the vehicle received from the user device in the vehicle. 4. The method of claim 1, wherein displaying an indication of the optimal speed profile on the user device comprises dynamically displaying a traffic signal indicator for each traffic signal device of the at least two consecutive traffic signal devices, the traffic signal indicator indicating a predicted status of the traffic signal device at a time at which the vehicle is predicted to reach the traffic signal device based on the optimal speed profile. 5. The method of claim 4, wherein an intensity of the indication of the optimal speed profile displayed on the user device indicates a certainty of the predicted status of the traffic signal device, a higher intensity of the indication of the optimal speed profile indicating a more certain predicted status of the traffic signal device. 6. The method of claim 1, wherein displaying an indication of the optimal speed profile on the user device comprises dynamically displaying a traffic signal indicator for each traffic signal device of the at least two consecutive traffic signal devices, the traffic signal indicator indicating a predicted status of the traffic signal device at a time at which the vehicle is predicted to reach the traffic signal device based on a current speed of the vehicle received from the user device in the vehicle. 7. The method of claim 6, wherein an intensity of the indication of the optimal speed profile displayed on the user device indicates a certainty of the predicted status of the traffic signal device, a higher intensity of the indication of the optimal speed profile indicating a more certain predicted status of the traffic signal device. 8. The method of claim 1, wherein displaying an indication of the optimal speed profile on the user device comprises dynamically displaying an indicator of time remaining before the status of at least one of the at least two consecutive traffic signal devices changes. 9. The method of claim 8, further comprising dynamically displaying an indicator of an expected arrival time at the at least one of the at least two consecutive traffic signal devices based on a received current speed of the vehicle from the user device in the vehicle. 10. The method of claim 1, wherein the optimal speed profile further comprises a speed display comprising a plurality of concentric arcs, each arc of the plurality of concentric arc indicating the range of speeds required to pass through the least two consecutive traffic signal devices without stopping. 11. The method of claim 1, wherein sending the travel route and the optimal speed profile for the vehicle to the user device comprises: sending a plurality of displays displaying the travel route and the optimal speed profile to the user device;tracking an adherence to speed limits of the vehicle based on the display sent to the user device;identifying a safest display of the plurality of displays based on the tracked adherence to speed limits of the vehicle; andsending the safest display to the user device in future iterations of the method. 12. The method of claim 1, further comprising: determining, by the system, that one or more public webcams capture and display a traffic signal device;monitoring the one or more public webcams to determine traffic signal device status information, the traffic signal device status information including one or more changes in a signal state of the traffic signal device and times at which the changes occurred; andaggregating the traffic signal device status information to generate a traffic device signal mapping for the traffic signal device. 13. The method of claim 1, further comprising: receiving, from a user device, user input indicating one or more changes in the signal state of the traffic signal device; andgenerating a traffic device signal mapping for the traffic signal device based on the user input. 14. The method of claim 12, further comprising using traffic signal device status information for one or more traffic signal devices to obtain traffic signal device status information for one or more additional traffic signal devices. 15. The method of claim 12, further comprising determining a travel route for a vehicle based at least in part on traffic signal device mappings for traffic signal devices along one or more candidate routes from a current location of the vehicle to a destination location. 16. The method of claim 12, wherein the traffic signal device mapping includes: data describing the status of the traffic signal device at different times of day and different days of a week; andtiming information indicating a length of time that the traffic signal device remains in various states.
