The Research of Carbon Emission Computing Model for Disjunct Road

摘要

The factors that influenced CO2 emission of a disjunct road in the operational life cycle were analysed in this paper. The two significant factors, gradient and speed, were underlined. And the secondary factors were elided. Using relative impact factors, introducing the concept of time, the CO2 emission model of a disjunct road in the operational life cycle was established. In addition, the optimal value for each impact factor was received. The results laid a theoretical foundation for further study of the lower-carbon highway, and promote its progress.
