Since the opening of the Hsueshan tunnel on June 16, 1995, the number of tourist trips has increased during consecutive vacations and holidays, and traffic congestion has become the common status. The Freeway No.5 related management proposed to implement mainline metering measure on the Freeway No.5 northbound road of the Yilan City to Toucheng City. However, today’s freeway ramp metering control strategies are the fixed-time plan that cannot process the real-time traffic conditions effectively. The research aimed at developing a green metering model from the perspective of sustainable development of the transportation system, combined with the traffic flow model and CO2 emission estimation model of The Freeway No. 5, and maintaining the traffic flow at the south entrance of the Hsueshan tunnel, without compromising traffic flow. The minimum amount of carbon dioxide emissions of vehicles traveling on the road segment is the target. The green metering rate and carbon dioxide emissions of the mainline segment are explored. The differences in carbon dioxide emissions under the control of the green metering mode and the fixed-time plan are analyzed, and the carbon reduction benefit is assessed. The empirical analysis results of this research shows that under the control of the green metering mode in the mainline section of Freeway No.5, the carbon reduction effect can be as high as 14%. Shows that the green metering mode has the effect of energy saving and carbon reduction. This result provides traffic managers with a reference for future green transportation decisions.
