Trucking Company Increases Green Assets with STC System
TEMPE, AZ - 04/26/2010 - Knight Transportation, a Phoenix-based LTL carrier,
has gone green in more ways than one. The company recently added several
kilowatts of solar roofing to its covered parking area at its main facility
in Phoenix. The grid intertie system produces electricity from the sun
during the day and pushes it back onto the grid to offset the company's
energy use.
Furthermore, Knight continued by adding 'green' traffic safety to a
crosswalk in their main parking lot. Designed and furnished by Solar Traffic
Controls (STC)the system uses four TS500 lamps from Traffic Safety
Corporation (www.xwalk.com) which illuminate the crosswalk and warn
motorists of pedestrians crossing.
To alert motorists, the system uses 8-inch amber flashers in conjunction
with W11-2 signs and W16-7 arrow signs on either side of the crosswalk. The
system is activated by a microwave detector as pedestrians approach the
crosswalk. Adjustment of the sensors is done with an infrared handheld
remote which allows users to tweak the sensitivity, range and other related
parameters.
All the in-roadway lamp controls were designed by STC for Traffic Safety
Corp. and include an LCD user interface for adjustment of timing parameters.
The LCD also displays key system parameters including programmed run time,
flash rate, activation source and count since last reset.
Because all the indicators are LED and are very efficient, the entire system
is powered by a 30W solar array. The sealed battery provides up to 5.4 days
of backup for the system running in max bright for the projected average
daily duty cycle.
Solar Traffic Controls is the Traffic Safety Distributor for Arizona and New
Mexico and has fielded many systems like these over the last five years.
Many of the systems include radio-activated, advance flashing beacons; some
include pedestrian detection mats. Most systems are deployed at municipal,
county and state agencies, yet they are equally applicable at industrial
facilities to provide a measure of safety for employees.
Most of the components used in the project, including the LED lamps for the
flashers, were made in Arizona thus providing benefit to the local economy.
