Oakland County Autoscope Detection Case Study
The Oakland County Autoscope detection project helped improve vehicle detection and signal timing across several busy intersections in Oakland County, Michigan. Because traditional loop detectors sometimes miss vehicles in complex lane patterns, the county needed a better detection solution to support traffic operations and reduce congestion.
Project Background
Oakland County has a large and varied traffic network with many arterial corridors that experience high vehicle volumes. In particular, intersections where multiple turn and through movements occur were difficult to manage using conventional detection systems. Therefore, the county sought a more accurate detection method that could differentiate vehicles reliably and improve signal responsiveness.
Autoscope Detection Solution
Econolite deployed the Autoscope® video detection system at several targeted locations. Autoscope uses advanced video processing to detect vehicle presence and movement across lanes and turning junctions. In addition, it sends accurate detection calls to the signal controller so timings can update in real time.
Because Autoscope analyzes video feeds rather than relying solely on loops, detection remains reliable even when vehicles queue closely or overlap in adjacent lanes. This means controllers can react more accurately to changing traffic conditions, reducing unnecessary delays and improving overall signal performance.
Deployment & Field Integration
Econolite installed Autoscope units and integrated them with existing traffic signal controllers. Then, technicians worked with Oakland County traffic engineers to calibrate detection zones and verify performance. Because field conditions change with time of day and season, multiple rounds of testing helped ensure detection accuracy under various traffic patterns.
In some areas, communication upgrades were needed so that data from Autoscope could flow seamlessly to the traffic management center. These upgrades improved the overall responsiveness of the signal system and helped operators make quicker adjustments.
Operational Benefits
As a result of the Oakland County Autoscope detection deployment, the county realized several key improvements:
- More accurate vehicle detection across multiple lane patterns
- Improved signal timing and reduced delays
- Better responsiveness to peak traffic conditions
- Greater confidence in detection data for planning
- Enhanced performance for vehicles and pedestrians
This Autoscope deployment strengthened the traffic system’s ability to manage real‑time conditions and support long‑term operational goals.
