Abstract
A system and method for controlling transportation traffic signal beacons including powering a signal, encoding a signal state, and decoding the signal state at the beacon is presented. Furthermore, traffic signal beacons may be placed along the length of a bridge to warn of a bridge collapse. The metallic cable that powers the beacons may also function as a bridge collapse detection sensor.
