This disclosure describes the use of a number of different technologies to optimise the approach of vehicle drivers to automated traffic signals. This would be achieved by relaying the timing of the next signal change to a device that can translate this data into actionable information such as 'maintain speed' or 'slow down'. The methods for relaying this information are described as occurring over an infrared signal that is received by the camera imaging sensor on a Smartphone. The imaging chips on Smartphone cameras are inherently sensitive to infra-red light and in the majority of Smartphones models there is no infra-red filter to block this light. The relay of the traffic information could therefore be achieved by sending out a loosely directional infra-red signal that could be picked up and interpreted by the Smartphone camera with the appropriate software.
