Performance Projections
In order to maintain a State of Good Repair, roughly 120 traffic signals need replacement each year. Currently, approximately 50-60 traffic signals are replaced each year. Of those, 45-55 signals are programmed under the signal replacement program and 5-10 signals are replaced under other state projects annually.
Asset Valuation
$830,500,000
Asset value is estimated using the replacement value. For traffic signals, replacement value is the product of traffic signal and unit construction cost. For 2,560 traffic signals:
2,560 * $320,000 = $819,200,000
For 226 Overhead flashing beacons:
226 * $50,000 = $11,300,000
Measures & Goals
There are no Federal requirements at this time. CTDOT has set the following traffic signal condition goal:
- 80% or more of state owned traffic signals in a SOGR

Traffic Signals Performance Projections
Note: Current Funding" shown in the graphs is limited to funding programed to address State of Good Repair. Projected performance is expected to be greater due to asset improvements funded through CTDOT's Capital Program which are not captured. The Department will soon be able to capture this funding through a project asset data system in development.

- Based on funding as of 12/31/22
Traffic Signals Performance Projections
Note: Current funding level includes $29 million for TAM Traffic Signals Preservation projects, $20 million for Computerized Traffic Signal System (CTSS) replacement projects, and $12 million for Traffic Signal Safety & Technology projects. The CTSS projects will affect SOGR rating; Traffic Engineering is taking on the prime designer role starting FY2024. The Traffic Signal Safety & Technology projects are funded through FY2026 and will not affect SOGR rating.
