Signal Timing Optimization with Consideration of Environmental and Safety Impacts

Transportation agencies are increasingly realizing the importance of performance measurement and management. However, the main performance measures used in assessment and optimization of signal timing have been mobility measures (such as travel time and/or delays), with limited consideration of environmental and safety impacts. Consideration of these measures is important, particularly with the increased emphasis on performance measurement and management of transportation systems. Performance measurement requires the consideration of a wide array of measures; which should be mapped to agency goals and objectives, and to identified issues associated with the region or specific system under consideration. Some efforts have been conducted to incorporate fuel consumption and emissions, and to a much lesser degree safety, in signal timing optimization. Despite the availability of some studies on these subjects, no guidelines or tools are available to assist traffic engineers in their evaluation and optimization of signal control based on related measures. The goal of this research is to recommend methods and models for assessing and reduce environmental and/or safety impacts associated with signal timing, in combination with mobility measures.
