In 1993, I received authorization to experiment from the California Traffic Control Devices Committee (CTCDC) to implement "warning lights" in the road to alert pedestrians to the potential presence of a pedestrian. We presented the concept to the City of Santa Rosa, CA, and the City Council unanimously approved the concept. However, they mandated that we receive the proper authorization to try this novel concept. Both excited and a bit nervous, we now had this Authorization to Experiment, but had no idea of exactly how this device would be produced or how well we could get it to perform!

The City of Santa Rosa offered three locations in which to begin, along with one "beta" test location at the City Corporation Yard that would allow preliminary evaluations.  This proved to be most beneficial in getting on the right track very early in the process.
