System warns drivers of hazards at Jamberoo Action Park, Australia
TEMPE, AZ - 01/10/2013 - STC has furnished a modified version of its Solar
Ped-X control package for a project in Australia.
A new water "action park" was opened in October 2012 in a rural area south
of Sydney. The roadway servicing the facility is a single lane in each
direction and includes a long right turn lane (think left turn lane in the
US) for vehicles turning into the facility.
As the park prepared to open, traffic engineers realized cars in the right
turn queue could back up and block the through lane thus backing up traffic
along the highway. This backup, coupled with the fact most traffic was
coming over a hill to reach the park, created a hazard for motorists coming
over the hill into the traffic backup.
Working with Traffic Tech PTY, STC modified a version of the Solar Ped-X
crosswalk system for the project. Traffic Tech furnished an i-Stud sensor
for the project which was placed at the end of the right turn lane to detect
vehicles backed up in the queue.
This provides a call into a modified Solar Ped-X control panel which allows
for time filtering of the input. When a valid detection occurs the master
unit, at the detector station, loads the pre-programmed run time value into
the local operating register and radios the value to the slave beacon
station processor. The master includes a status LED to indicate when the
slave lamps are flashing.
The slave beacon station was located in advance of the top of the hill and
included a large warning sign as shown in the photos. The beacons are
8-inch amber DC LED lamps manufactured by STC at its Tempe, AZ facility.
Communications between points is done using a Frequency Hopping Spread
Spectrum radio system. Even though Australia does recognize a license-free,
900Mhz ISM band, it has a tighter bandwidth than the US. Consequently STC
built the units with US approved radios and then removed them prior to
shipment. The same radio manufacturer was offering product through
distributors in Australia which met the country's standards.
STC engineering was able to talk the Traffic Tech engineers through the
configuration of the units over the phone to complete the radio portion of
STC performed all the solar power system design for the project. Traffic
Tech used this information to source all the needed modules, mounts and
batteries from local vendors thus keeping international shipping costs down.
