日本的二氧化碳（CO2）排放量，特别是由机动车交通引起的排放量，逐年增加。本文基于了解这一背景，提出了一种减少车辆二氧化碳排放的交通信号控制方法。首先，应用交通流模拟模型来获得广域交通流，从而可以建立模拟器来获得行驶车辆产生的二氧化碳排放量的估计值，同时考虑到每辆车的状态。使用模拟器对二氧化碳排放量与延误时间和交叉口停车次数之间的关系进行了分析，从而提出了一种新的交通信号控制方法，有望帮助我们实现减少二氧化碳排放量的目标。然后，在川崎市的主要干道上进行了模拟实验，以验证新方法，与当前交通信号控制方法减少的废气水平相比，二氧化碳排放量减少了约 7%。结果，作者证实了新方法是有效的。
The level of carbon-dioxide (CO2) emissions, particularly of those caused by motor traffic, has been increasing year after year in Japan. This paper proposes a traffic signal control method to reduce vehicle CO2 emissions based on understanding this background. First, a traffic flow simulation model was applied to obtain wide area traffic flows, so that a simulator could be established to obtain an estimated figure of CO2 emissions generated by traveling vehicles while considering the state of each vehicle. An analysis of relations between CO2 emissions and both of delay time and the number of stops at intersections was conducted with the simulator, which resulted in a proposal of a new traffic signal control method being expected to help us reach our target to reduce CO2 emissions. Then, simulation experiments were conducted on major arterial roads in Kawasaki City to verify the new method, resulting in a roughly 7 % reduction of CO2 emissions from the levels of the exhaust gas reduced by the current traffic signal control method. As a result, the authors confirmed the new method to be effective.
