STC installs 4th and 5th In-Roadway Lighting Systems in Casa Grande, AZ

TEMPE, AZ - 09/01/2009 - STC was awarded two In-Roadway Lighting (IRWL) systems for crosswalks in the City of Casa Grande, AZ, this past spring. The systems were delivered at the end of June and installed by the city's public works department in July 2009.

These represent the fourth and fifth systems installed around Casa Grande during the last three years.

The equipment consists of TS500 IRWL fixtures from Traffic Safety Corporation (TSC) of Sacramento, CA. The equipment is all solar-powered and features advance flashers with dual 8-inch indications. The solar power adapter, designed and built by STC for TSC, features control logic with a proprietary program and an LCD interface screen.

The software can be upgraded to operate in both button activation mode and school zone mode in which all the equipment activates based on time of day and day of the week. All units fielded thus far can have their programs upgraded via connection to a laptop or through the use of a memory chip that copies to the controls upon application of power.
 
Both systems feature a license-free contact closure radio with built in supervisory function to ensure the communications link between the power adapter and the advance flashers. The pedestrian interface is a Polara Bulldog button assembly which provides both an audio and visual feedback to user when pressed. To date, the city has been pleased with the systems, especially their reliability and low maintenance. STC and Traffic Safety have worked diligently to provide trouble-free, solar-powered equipment. It should be noted that STC did win the project through a bid process and was awarded the project as the most responsive bidder.
