Case Study: City of Temecula achieves 14% faster travel times and 29% fewer stops with McCain Inc's QuicTrac adaptive signal control

Quictrac™ Adaptive Software Reduces Arterial Congestion and Residual Queuing on Freeways, Promoting Mobility for City Residents

The City of Temecula was struggling with heavy congestion on seven major arterials covering 18 miles and 83 signalized intersections, with two daily peak periods and persistent queuing at I‑15 off‑ramps due to unresponsive signal coordination. McCain Inc deployed its QuicTrac adaptive control software to address these challenges and better integrate the city’s signals with Caltrans freeway interchanges.

McCain Inc implemented QuicTrac across the corridors, upgraded detection and timing plans, and established communication with Caltrans signals so signals could optimize timing in real time. The deployment delivered measurable benefits: 29% fewer stops, a 17% increase in average speed, 14% reduction in travel time, 81.3% of intersections showing reduced delay, a lifetime benefit‑to‑cost ratio of 30:1, $2.6M in annual travel‑time savings, about $437k annual fuel savings (and 120,000 gallons saved in year one), plus reduced emissions.
