Abstract:
This report identifies and recommends measures of impact that are applicable to the operation of at-grade light rail crossings within traffic signal systems. The key point in identifying measures of impact is to maintain consistency with traffic signal measures of impacts. The recommended measures of impact include average delay and queue length. This report illustrates how the analyst can apply both manual calculation methods and computer models to estimate these measures of impact. Included in the discussion is a screening procedure that is designed to minimize total work effort by identifying impacts and mitigating them with the least intensive analysis method. However, if the analysis results are marginal, then full simulation of the traffic signal system including the light rail line is warranted. The recommended programs for such evaluation of TRANSYT-7F for simpler problems and Traf-NETSIM for complex problems and analysis of system variances.
