Development of analytical tools for evaluating operations of light rail at grade within an urban signal system. Interim report 3. Research report, September 1991-August 1994
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. The 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 desinged 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 are TRANSYT-7F for simpler problems and Traf-NETSIM for complex problems and analysis of system variances.
