Annual maintenance costs for a traffic signal control system upgraded from five non-coordinated actuated signals to five coordinated actuated signals is $2,434.40.
Estimated annual maintenance costs for coordinated actuated signals in Gloucester, Virginia.
- Converting the non-coordinated actuated signal control system to a coordinated system will increase annual traffic controller maintenance costs from $200 to $300 per intersection.
- The "net present value" over 10 years for the system maintenance costs is $1,621.60 per year for the non-coordinated system and $2,434.40 per year for the coordinated system.
