Development of Tool for Assessing Impact of Automated Driving Systems on Traffic Flow and CO₂ Emissions

抄録

We have developed a tool for visualizing the CO₂ emissions of vehicular traffic, which can quantitatively evaluate how the introduction of automated driving systems might affect traffic flow and, consequently, changes in the amount of CO₂ emissions from vehicular traffic. To develop this evaluation tool, we combined traffic simulation with CO₂ emissions models and performed necessary verifications in accordance with an international joint report issued as part of NEDO's “Development of Energy-saving ITS Technologies” project. In addition, we used the tool to evaluate certain automated driving systems in specific scenarios, where the tool proved applicable to the evaluation of those systems.
