Challenges

High commuter volumes as well as local destination route usage, high variability from nearby schools and frequent emergency vehicle preemption due to a nearby hospital

Previous signal management

Coordinated timing plans

Grant Road is a major arterial in Mountain View. It experiences high levels of variability due to its adjacent land uses and close proximity to three freeways,
I-280, Highway 85 and Highway 237. Traffic generators near the corridor include residential areas, commercial offices, schools and a hospital. The corridor is a commuting route as well. Frequent emergency vehicle preemptions due to the hospital also challenge the roadway’s traffic flow.

The City selected InSync for use after Rhythm Engineering was the successful respondent to a competitive RFP. The City issued the RFP to procure an adaptive system “to address the continuous and sometimes unpredictable fluctuation in traffic and pedestrian demand on the corridor.”
