Project Description:
ADVANTEC was retained by the City of West Covina design traffic signal upgrade plans at three intersections along Azusa Avenue. Traffic signal upgrade along Azusa Avenue included installation of new ADA compliant ramps, protected left-turn phasing (PPLT), replacing existing 8” signal vehicle heads with 12” LED signal vehicle heads, pedestrian countdown signals, emergency vehicle preemption (EVP) detectors, new signal conduits and complete rewiring of intersections using multi-conductor cables. New timing sheets to incorporate the PPLT and EVP were also prepared for all three intersections.
