Phoenix Area Light Rail Line adds STC Solar Flashers

TEMPE, AZ - 02/28/2008 - Valley Metro, the Phoenix area light rail agency, had a recurring problem at a freeway off ramp where the light rail line went under State Route 143. Despite being clearly signed for high voltage and railway wiring and the height restrictions, large profile vehicles continued to exit the freeway and hit the wiring .

Valley Metro personnel decided the next step to enhance the signage was to add flashers. Solar Traffic Controls made a site visit to assess possible mounting locations for the equipment. It was decided that the flashers would be added to an existing sign assembly with both high voltage and height restriction information on it. The sign package was supported by a dual square tubing assembly on slip bases.

STC engineering staff designed a special enclosure mount and solar array mount to accommodate the non-standard installation. Staff from CS Construction were selected by Valley Metro to install the equipment under the supervision of STC personnel. The equipment was installed and put into operation at the beginning of March 2008 and should not require any maintenance on the solar equipment for at least 5 years.
