McCain Inc., a leading manufacturer and supplier of intelligent transportation systems, traffic control equipment and parking guidance solutions, today announced results measuring the effectiveness of McCain's adaptive signal control software deployed on San Marcos Boulevard -- the City of San Marcos's new "Smart Corridor." The study proved that the adaptive software system significantly improved traffic flow on San Marcos Boulevard, the second busiest arterial in San Diego County.
McCain's QuicTrac™ adaptive control system, aimed at reducing stop-and-go traffic by coordinating signal timing along the corridor, was surveyed for travel time reductions, associated costs and environmental benefits. The study focused on peak travel times both pre-and-post implementation of the signal control software. During peak travel periods the comparisons revealed that delay times were reduced between 19% and 46% depending on the time of day, significantly higher than anticipated. These reduced travel times provide a 7.8% average reduction in fuel consumption, resulting in reduced harmful emissions.
"Previously, the City of San Marcos optimized this corridor to meet the growing demand of this busy arterial. The city expected successful results from the new software system, but no one anticipated these kinds of results," said Jason Stack, principal of Stack Traffic Consulting, Inc. "Typically, we would see similar results on a corridor that has never been optimized, so gaining this level of improvement is outstanding for the City and residents."
With an average of 22,000 to 46,000 vehicles traveling the San Marcos Boulevard corridor daily, the City of San Marcos desired a solution that would provide the maximum benefit to the public at a minimal cost to the city. The McCain adaptive traffic control system surpassed expectations with a 29.7% average decrease in eastbound delay times by distributing on-demand cycle lengths, alleviating stop-and-go traffic. In addition, McCain's solution delivered the City of San Marcos with an 8:1 benefit to cost ration on travel time.
"We are excited to have received results that truly demonstrate adaptive control software's range of capabilities," said Brian Wagner, ITS solutions manager for McCain Inc. "Studies that yield these types of results will further establish adaptive technology as a premier solution in the traffic industry."
About QuicTrac
McCain's QuicTrac adaptive control software operates through the collection and analysis of real-time data from field detectors, loops or video, establishing traffic flow and demand. The software then runs a series of advanced algorithms to determine and coordinate optimum signal timing for the entire corridor. By coordinating traffic signals based on current conditions, the technology provides a series of green lights, expediting groups of vehicles through arterials.
