Fortran Traffic and STC Provide AC RRFB Systems for University Roundabout

AC RRFB - Solar Traffic ControlsTEMPE, 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 parameters.

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.
