城市路网中车辆碳排放量的影响因素研究

Research of Influencing Factors on Vehicle Carbon Emissions in Urban Road Network

在城市公路网中,一些因素可能会影响车辆平均公里碳排放量(Average Kilometric Vehicle Carbon Emission,简称AKVC),特别是在大城市的公路网中,这些因素可能更加多样化。研究中的因素包括登记车辆数量中每公里的交叉口数量、道路部分与总面积之间每公里的交叉口数量以及道路部分与车辆数量之间的总面积。研究发现,每公里交叉口数量是影响地区路网AKVC的唯一重要因素,其他所有因素对AKVC的影响均不显著。从研究中可以看出,由于每公里交叉口数量是道路网络中减少车辆碳排放量的最具影响的因素,这意味着应该控制或减少城市道路网络中的交叉口数量。

In the urban road network,some factors may influence the average kilometric vehicle carbon emission(AKVC),especially in the road network of large cities.These factors may be more diverse.Factors in this study include the number of intersections per kilometer on the number of registered vehicles,the number of intersections per kilometer between the road section and the total area,and the total area between the road section and the number of vehicles.The study shows that the number of intersections per kilometer is the only important factor affecting AKVC of the regional road network,and all other factors have no significant impact on AKVC.The study also shows that the number of intersections per kilometer is the most influencing factor to reduce the vehicle carbon emissions in road networks,which means that the number of intersections in urban road networks should be controlled or reduced.
