城市公交子系统,即地面的电汽车公交系统,作为城市交通系统的重要组成部分其能源消耗量日趋增大，而对城市公交子系统能源消耗结构的研究还不成熟，从可持续发展的角度考虑，迫切需要研究城市公交子系统的能源消耗情况.本文分析了城市常规公交子系统能源消耗结构，考虑公交车辆全寿命周期中的能源消耗，通过引入能源费率参数，建立了城市常规公交子系统能耗模型，并对模型进一步处理得到其分解模型.以北京市常规公交子系统为案例，测算了2010年北京市常规公交子系统的全寿命周期成本、能源费率和能源消耗费用，并对所得结果进行比较分析,对城市公交子系统的结构调整给出合理性的建议.

Energy Consumption Models for Urban Bus Transport

The sub-system of urban public transit is the public transportation system on the ground.It is an important part of urban transport system and its energy consumption is increasing in these years.Because the researches on the energy consumption structure of urban public transit system are still not mature,exploring the energy consumption of urban public traffic system from the perspective of sustainable development is urgently needed.Considering the life cycle of the public vehicle energy consumption,this paper analyzes the energy consumption structure of urban public transit system.The energy consumption structure is established by introducing the energy cost rate parameters.It takes the public transit system of Beijing for example to calculate the life cycle of the public vehicle energy consumption,energy cost rate parameters and the energy consumption cost in 2010.Furthermore,the paper analyzes the case results and gives reasonable suggestions on restructuring urban public traffic system.
