Abstract

Modern traffic control systems are complex entities whose performance should be thoroughly quantified prior to deployment. However, many of the advanced features available with this control equipment, such as preemption and real-time control strategies, are typically proprietary in nature, and therefore not incorporated into standard simulation models. Since it is not desirable for the engineer to learn in a field environment, under live traffic conditions, this research presents a rational procedure for evaluating and validating such control strategies in a laboratory setting. This document explores three aspects of traffic signal systems, which include the advanced control settings for single controller diamond interchanges, the impact evaluation of emergency vehicle preemption on signalized corridor operation, and an analysis of the more complex Traffic Responsive (TRP) control strategies available with the modern equipment. Each of these areas have been evaluated using quantitative data obtained from the CORSIM simulation model that communicates with the actual control equipment through the use of a Controller Interface Device (CID). The results for each of the study areas have been tabulated, plotted, and discussed. These case studies serve as models of how INDOT may want to request future traffic signal timing contracts to structure and present the performance of signal timing design alternatives.
