The average cost to implement Adaptive Signal Control Technology is $28,725 per intersection.

Adaptive signal control technologies (ASCTs) have been proven effective in providing operational benefits, but agencies in the United States have been slow to adopt these technologies. One of the major reasons for the lack of ASCT implementation is lack of knowledge about the operational and safety benefits and costs of ASCT. This report found that the cost of ASCT per intersection was estimated between $46,000 and $65,000. Excluding the outliers, with seven agencies reporting, the average cost to implement ASC technologies averages to $28,725 per intersection to implement. The average cost of ASCT was given by the type of system as well as the type of detection technology. The average cost of ASCT per intersection was highest when used with video detection and lowest when used with magnetometer detection technology. The charts below from the report provide additional detail per intersection based on the type of adaptive system and the type of detection technology.
