A Systematic Evaluation of the Impacts of Traffic Condition Information on the Reduction of On-road Mobile Emissions

With the development of traveler information system questions raised: how much does the technology impact travel behavior, and what is its effectiveness of mitigating traffic congestion and thus reducing transportation-related emissions. Even though the evaluation of traveler information systems has been performed in several studies, they have not been fully investigated towards different format of information. In addition, although the technology is designated to improve traffic condition and air quality, very few studies have been performed to investigate the impacts of the technology on traffic flow and therefore few systematic methodologies or models have been proposed to measure its effectiveness in improving the performance of the transportation system. The goal of this research project is to evaluate the impacts of traffic condition information on the reduction of on-road mobile emissions. To this end, this research will: (1) review and synthesize the evaluation studies on the traveler information systems; (2) investigate the travel behavior change in the presence of pre-trip and en-route traveler information; and (3) develop models to estimate the benefits of traveler information on traffic-flow improvements and transportation-related emissions reduction.
