Challenges

High pedestrian volume, unpredictable shifts in demand due to nearby highway, sports stadium and schools

Previous signal management

Uncoordinated fully actuated

The City of Salinas installed InSync at five intersections to manage the high pedestrian and vehicle traffic along Main Street. Prior to InSync’s installation, the corridor operated in free mode. With no coordination plan, the traffic control system served pedestrian movements upon request. Consequently, the high pedestrian volume crossing the corridor from Monterey Bay disrupted traffic flow and exacerbated congestion on the busy arterial. City and traffic officials concluded that timing the intersections along the corridor would not solve the problem and installed InSync shortly thereafter. InSync’s compatibility with the city’s existing equipment and ability to incorporate pedestrian movements into its global coordination and local optimization creates significant safety and economic benefits for the Salinas community.
