Traffic Signal Inspector

The IMSA Traffic Signal Inspector Certification Program is designed to ensure public safety by helping individuals to understand fundamental concepts associated with the inspection for construction of traffic signal installations.  Traffic Signals are a key element in our transportation system and the proper operation of these signals is of paramount importance in maintaining reasonable levels of mobility.  Knowledgeable traffic signal inspection is required to ensure that proper/specified construction practices are followed during signal installation resulting in signals that operate as intended. Knowledgeable inspection is also a key element in limiting the liability exposure of governmental agencies associated with malfunctioning traffic signals. 

Traffic Signal Inspector Certification is recommended for all individuals involved in the inspection of traffic signal construction.  It is also a valuable course for contractor personnel, since it provides an inspector’s viewpoint of traffic signal construction. 

Topics covered in the Traffic Signal Inspector Certification Course Manual include:

  • Introduction to Traffic Signal Inspector
  • Inspection of Underground Facilities
  • Inspection of Traffic Signal Supports
  • Inspection of Overhead Equipment
  • Inspection of the Vehicular and Pedestrian Detection Systems
  • Inspection of the Controller Assembly
  • Safety Requirements
  • Final Acceptance and Turn-On

    About the Program

    This is an entry-level seminar to review basic and advanced methods of Temporary Traffic Control in Work Zones. This course reviews principles for the design,
    installation, and maintenance of traffic control devices and identifies applicable standards for common urban, rural, and freeway situations. You will review traffic
    control theory and devices, hand signaling devices, typical situations for construction, and traffic terminology. Problems of traffic control may occur when traffic must be moved through or around road or street construction, maintenance operations, utility work, and incidents on or adjacent to the roadway. This two-day seminar establishes principles to be observed in the design, installation, and maintenance of traffic control devices, and identifies standards where applicable. The general principles outlined are applicable to both rural and urban situations.

    You will review:

    • Guidelines for using traffic control devices
    • Typical situations for construction
    • Traffic terminology
    • Work zone temporary traffic control and safety review notes
    • State and/or local design standards
