Traffic Signal Audit Guide

Overview

This guide is provided to inform traffic engineering managers of a general audit process that can be used to evaluate the effectiveness of their program management of traffic signal and associated systems. An audit is performed to verify that people in an organization are doing what they planned to do in accordance with an established management system or the nationally-accepted state-of-the-practice. This guide provides general information on the types of questions that might be asked to assist in the continuous improvement of traffic signal systems management. It is not a substitute for the work of an independent audit team.
