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. |
