Previous signal management

Coordinated timing plans

Columbia County, Georgia was the first community to deploy InSync:Fusion which integrates existing detectors such as inductive loops with InSync’s proprietary video detection for superior performance. Due to the challenges of coordinating intersecting arterials with high, variable volume, the existing coordinated timing plans on Washington Road were unable to overcome congestion.  In choosing InSync, the county gained a traffic management solution that reduces congestion, provides remote video monitoring, saves motorists time and fuel, improves safety and accomplishes each of these objectives without requiring additional staff time. Thrilled with InSync’s performance on one sector of Washington Road, they soon deployed InSync on a second sector, resulting in a continuous network of 12 InSync intersections. Ultimately, Columbia County achieved another industry first – they were the first agency to outfit every traffic signal in their jurisdiction (62 total) with InSync technology.


Daily Benefit Annual Benefit
Vehicle Hours of Travel
895 hours 232,764 hours
Fuel Consumption
671 gallons 174,403 gallons
75,362 stops 1,959,099 stops
Total Economic Benefit $23,313 $6,061,270

These benefits to the community are based on the results of InSync on 12 intersections along Washington Road. All calculations are based on normal weekday travel and the results indicate approximate benefits to drivers. Because Columbia County operates additional InSync intersections not studied here, benefits are likely greater.

The North Sector study is based on an assumption that the deployment impacts
75% of ADT (40,000 vehicles). The South Sector study captures 37% of ADT; off-peak results are not included in the South Sector benefit calculations.

It was amazing to see the transformation in the road in mere minutes after the system was turned on. In the past five years, I have driven this corridor several times a day. I can clearly remember only making it through the corridor, without stopping, one time in those five years. We were able to do it three times in a row within 30 minutes of activating the system.
