Summary Information

In Indiana, a corridor with approximately 100 intersections was upgraded to improve signal timing optimization, enable capacity analysis, and support future adaptive signal control operations. Previous research indicated that adaptive signal control systems could be implemented for $65,000 per intersection.[1] On corridors where actuated-coordinated operations have been established and traffic detection is available, installation of adaptive signal control systems is relatively simple. For corridor wide projects, controller-based high resolution data collection systems can be used to facilitate signal timing optimization and the monitoring of performance measures.

The tables below summarize estimated per intersection costs to deploy controller-based high resolution data collection in Indiana.
