Fortran Traffic and STC Provide AC RRFB Systems for University Roundabout
TEMPE, AZ - 09/03/2013 - Solar Traffic Controls' Canadian distributor,
Fortran Traffic, furnished AC RRFB systems for the University of British
Columbia in Vancouver just in time for the new school year.
The goal is to provide pedestrian safety at a roundabout at the entrance to
the campus. Three of the four legs of the roundabout have crosswalks on
them. Each crossing leg consists of a three-pole system, two curb units with
buttons and a median unit with no buttons.
Each curb indication is an 80BKRRFBHS-T2 assembly which is a front-facing
dual 3-inch x 7-inch RRFB assembly with an end cap pedestrian confirmation
lamp. The median unit is an 80BKRRFBHS-T5 assembly with dual end cap
pedestrian lamps and front/rear facing 3-inch x 7-inch RRFB lamps. More
information on these units can be found at the STC website.
The control used for the lamps is an STC 80ACRRFB-50. This is an AC powered
RRFB/CRFB control unit with 50W AC/DC power supply, RRFB driver module, and
user interface module complete with LCD screen for adjustment of timing
The control unit registers a relative count of button activations for public
works departments and shows the operating mode on the LCD screen at any
given moment including maximum runtime values and current runtime values if
in operation. The controls are housed in a miniature P-style traffic cabinet
which is band-mounted to the pole.
The final owner of the project is the Ministry of Transportation and
Infrastructure of British Columbia. Traffic engineering for the project was
completed by DMD Engineering, a firm which has used STC and Fortran for
other projects in western Canada.
