Traffic Signal Operations and Maintenance Staffing Guidelines Dunn Engineering Associates

This report provides a guideline to estimate the staffing and resource needs required to effectively operate and maintain traffic signal systems. In 2007, the NTOC Traffic Signal Report Card (TSRC) assigned a grade of D nationally to how agency programs support the efficient operation and maintenance of traffic signals (5). The D grade indicates that relative to what is considered ?good practice?, overwhelmingly an ad-hoc approach is taken, resulting in some positive outcomes, but generally agency programs are not as effective as they could be.
