SZ Beacons with TraffiCalm DFB signs
TEMPE, AZ - 05/06/2013 - Surprise, AZ has long been a user of STC flashing
beacon products for school zone and pedestrian safety projects, as well as
emergency vehicle exit signals. In an effort to enhance school zone safety
in a particularly busy school zone, the city called on STC to upgrade an
existing solar flashing beacon system with Driver Feedback (DFB) signs.
Since the design of any successful solar-powered system is dependent on
three things - location, load and duty cycle - Surprise personnel knew it
was not possible to add additional load without adjustment to either the
solar-powered system or the system duty cycle.
Surprise selected the 9-inch DFB from TraffiCalm for the feedback device.
This defined the revised load for the system. STC had furnished the solar
flashing beacon system several years ago and they had been designed for a
higher duty cycle than the school was currently using or intended to use in
the future. As a result of the small increase in the load and the available
duty cycle, no changes to the power system were necessary.
STC Applications Engineer Jimmie Dixon assisted Surprise personnel with the
installation of the sign and the supporting equipment. As the sign is
equipped with an internal scheduling function, the city opted to continue
using the original STC-01 time clocks to run the systems and keep their
control configuration consistent with the rest of the equipment throughout
Studies by local engineering companies performed on completed STC projects
have shown that by combining school flashers with radar signs tends to have
a greater impact on driver compliance with posted speed limits in school
zones. STC can work with agencies to look at options for upgrading existing
beacon systems to incorporate DFB packages or to furnish new systems with
either 9-, 14- or 15-inch DFB signs from Trafficalm.
