Case Studies

Every community is different, with its own traffic patterns, hot spots and frustrations. The below case studies present a number of different scenarios where Rhythm Engineering products were successfully deployed to alleviate specific traffic issues.

Virginia DOT

Situation: Traffic flow issues in 13 corridors and 111 intersections in different parts of the state, each with a unique structure, volume, speed limit and control need.

Solution: Significant improvements in traffic flow, including up to 67% stop reductions, after deploying In|Sync across the state.

West Des Moines, IA

Situation: Excessive waiting at red lights near the local mall, Jordan Creek Town Center Mall, when the mall is closed and no cross traffic is present.

Solution: Adaptive system In|Sync deployed at 9 intersections along Jordan Creek Parkway controls green corridor with up to 56% reduction in stops.

San Diego, CA

Situation: Nearby highway, sports stadium and schools creates high pedestrian volume and fluctuations in traffic volume and demand.

Solution: In|Sync deployment at 5 intersections along the corridor provides optimal traffic control based on actual demand, eliminating unnecessary stops and delays resulting in up to 24% decrease in travel time.
