This paper describes an architecture for traffic signal control based upon the IEEE 1451 plug and play distributed smart sensor network standard. The system integration with a commercial of the shelf traffic controller requires a minimum of software modifications. This demonstrates an incremental path to integration of smart signals with conventional traffic signal devices. The system design focused on countdown timers for pedestrian signals because the current designs can give incorrect times when the signal timing changes. The system also demonstrates the ability to provide remote access to the call button to assist visually and mobility impaired pedestrians.
