InSync Type

InSync standard & Fusion

Challenges

High pedestrian volume and random fluctuations in traffic volume

Previous signal management

Coordinated timing plan

The City of San Ramon installed InSync along two busy signalized corridors that each intersect with Interstate 680. The agency’s goal was to achieve bidirectional progression on the corridors and reduce stops, travel time and delay. The independent DKS Associates study states, “The overall results show a significant reduction in system-wide travel times and stops under the InSync adaptive system.” The study also commented that the improved progression was not achieved at the expense of side street delay saying, “The average vehicle delay along the corridor decreases by approximately 27.7 seconds per vehicle. The average vehicle delay at observed minor streets increases by approximately 3.0 seconds per vehicle. The benefits of decreased delay along the mainline are far greater than the detriment of the increased delay at the minor streets.”

Calculations are based on Crow Canyon Road’s ADT of 37,466 vehicles and an assumption that the change impacts 70% of the ADT on that road, and Bollinger Canyon Road’s ADT of 41,802 vehicles and an assumption that the change impacts 60% of the ADT on that road.  All calculations are based on normal weekday travel and the results indicate approximate benefits to drivers.

New Traffic Lights Saves Drivers’ Money, Lower Emissions

People may not have noticed it, but those who drive on Crow Canyon Road or Bollinger Canyon Road during busy times of day are getting through faster — for the most part, anyway.

Project Highlight

InSync is achieving bidirectional progress in challenging conditions



I was very pleased with the quality of the two-way progression that InSync achieved in our city in spite of some difficult constraints.
