营运阶段公路碳排放量的影响因素及计算方法研究

公路路线设计中关于碳排放因素的考虑越来越受到重视。分析了营运阶段公路碳排放量的主要影响因素，并指出公路路线设计的相关参数是影响碳排放量的最关键的因素之一。从公路路线设计的角度出发，揭示了典型车型下车速、曲线纵坡坡度以及两者综合作用下碳排放的变化规律，提出了对应的碳排放关键参数的计算方法。

Study on Factors Affecting Carbon Emission of Highway in Operating Stage and Its Analysis of the Carbon Calculation Method

The factors relating to carbon emission are paid more and more attention to in highway route design. Herein the main factors affecting carbon emission of highway in operating stage were analyzed, and it was proposed that the parameter about highway route design is the most critical one among them. From the route design, the paper disclosed, for typical model, the change rule of carbon emission under the single action of vehicle speed, curve longitudinal gradient and the comprehensive action of the both, respectively; then the method calculating with the corresponded key parameter of carbon emission is proposed.
