State of Good
Repair (SOGR)
The SOGR for traffic signals, revised in 2024, uses a Good/Fair/Poor rating system for 4 components (structure, communication, detection, control box) of each traffic signal. The overall Good/Fair/Poor of the traffic signal is determined using a decision matrix of all 81 different possible outcomes. Good or Fair are considered SOGR.
Traffic Signal Age
- 45.8% of traffic signals are older than 25 years
- 1.5% of traffic signals are older than 54 years

Performance Projections
In order to maintain SOGR, roughly 120 traffic signals need replacement each year. With the new component-based SOGR, projections for the individual components are preliminary and are still being developed. Projections are expected to be enhanced in the future.This fact sheet includes funding for component replacement projects.
Asset Valuation
$1,260,265,000
Asset value is estimated using the replacement value. For traffic signals, replacement value is the product of traffic signal and unit construction cost. Traditional traffic signals:
1,543 * $375k = $578M
CTSS: 1,028 * $650k = $668M
Overhead flashing beacons:
226 * $60k = $13.4M

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.
Note: CTDOT adopted a new, component-based condition performance measure starting in 2024. The previous age-based performance measure underestimated the condition of CTDOT's signal system.
