  • The existing urban traffic structure was analyzed.The motor vehicle population, 100-kilometer fuel consumption and annual driving distance were taken as influence factors, the rate of influence factor was introduced as parameter, and the dynamic situation combination decomposition model of urban traffic energy consumption was set up by using logarithmic mean Divisia index(LMDI) model.Based on the change conditions of 3 influence factors, 12 situation combination modes were designed, and the change trends of urban traffic energy consumption under different situation combination modes were analyzed.Analysis result shows that the maximum increase amount of total energy consumption is 1.749 2×106 t standard coal, the energy consumption rates of 3 influence factors are 91.79%, -9.57%, 17.78% respectively. The minimum increase amount of total energy consumption is 5.506×105 t standard coal, the energy consumption rates of 3 influence factors are 128.10%, -52.34%, 24.24% respectively.Based on the increase speed of motor vehicle population, the 12 situation combination modes can be divided into 3 schemes such as low-speed increase scheme, middle-speed increase scheme and high-speed increase scheme.The maximum increase amounts of energy consumption for 3 schemes are 8.702×105, 1.309 7×106, 1.749 2×106 t standard coal, the minimum values are 5.506×105, 9.408×105, 1.345 5×106 t standard coal.
