Construction Inspection of Traffic Signals

Traffic signal projects must comply with specifications as required by the Caltrans Standard Plans and Specifications Manual. Inferior work on signals or inadequate traffic management during project construction can create potentially dangerous conditions with liability impacts for local agencies.

This one-day course provides training on best practices for the management and construction inspection of these systems, including examinations of wires, cables, signal heads, and pedestrian/vehicle detectors.
