摘要：	The annual evaluation of traffic signal systems on an agency level can be of great importance for identifying problems, self-assessment, budgeting, creating the strategy for future steps, etc. The most famous similar effort of this type is the National Traffic Signal Report Card (NTSRC), which is used as an evaluation methodology for agencies country-wide. The main difference in the proposed methodology is that it steps away from qualitative evaluation and grading, and presents a new set of procedures for implementation of quantitative, therefore more unbiased, evaluation methodology. The proposed methodology should enable self-evaluation and comparison between different agencies in terms of agency management, traffic signal operations, signal timing practices, traffic monitoring, data collection, and maintenance. For two agencies, the numerical and logical values of the answers were used in the evaluation process to obtain the preliminary results, and together with the factor of confidence, they were displayed to explain the evaluation process. The annual evaluation is supported by weekly/monthly evaluation which was developed as a set of dashboards with relevant signal performance measures. The dashboards were created to reflect performance and reliability of a specific signal system on a weekly/monthly level. The authors used data from ATMS.now signal system central software to illustrate how similar dashboards could be developed from any central software to enable operators to promptly and efficiently monitor various parameters of traffic signals. The main outcome of the study is a set of Excel evaluation spreadsheets accompanied with relevant user manuals.
