A rough estimate for four retiming plans (AM, noon, PM, and off peak periods) ranges from $2,000 to $2,500 per intersection.
The presentation, "Benefits of Retiming Traffic Signals: A Reference for Practitioners and Decision Makers About the Benefits of Traffic Signal Retiming," is based on an ITE report and brochure of the same title – products of the ITE Traffic Engineering Council’s project TENC-101-02. These documents describe the who, what, when, why, and how of traffic signal retiming.
Examples of successful retiming projects are also identified. Benefit cost ratios as high as 40 to 1 can be realized after traffic signal retiming is performed. Many factors such as skill level and expertise of professionals conducting the retiming study and equipment involved go into the costs of a retiming project. A rough estimate for four retiming plans (AM, noon, PM, and off peak periods) ranges from $2,000 to $2,500 per intersection.
