Summary Information

Adaptive Signal Control Technology (ASCT) systems collect data, evaluate traffic signal performance based on functional objectives, and then update signal timing in response. Florida DOT commissioned a project to evaluate the effectiveness of ASCT across Florida using a before and after study approach and document the advantages and disadvantages of different approaches and implementations. The study evaluated the implementation of two ASCT systems at selected arterial corridors from eight different locations in Florida: Gainesville, Deland, Panama City Beach, Sarasota, Panama City, Pinellas, Manatee, and Bartow. The eight corridors included in the study varied in length from 1.1 to 9.2 miles and most had a relatively low density of intersections. Annual average daily traffic (AADT) on the corridors ranged from 28,750 to 52,185 vehicles/day.

Cost information was obtained during interviews with operating agencies.  A questionnaire was developed and provided to the operating agencies for each site in advance of interviews.  Contract types varied among the agencies, with some structured as a lump sum and others categorized separately by procurement, installation and maintenance. For the analysis, researchers calculated overall cost values, including equipment, installation, training, and maintenance costs.   

Table 1 shows the implementation costs of ASCT for each corridor reported in the study. Researchers reported that ASCT was removed at one of the high-density locations, Gainesville, which was not included in the benefit-cost analysis.
