中文摘要：
基于元胞自动机交通流NaSch模型,提出元胞自动机混合交通流能耗公式,对混合交通流的能耗进行研究,通过数值模拟研究不同最大速度、不同车长的混合交通流的能耗;研究表明不同车长、不同最大速度以及混合比对混合交通流能耗均有不同的影响.
英文摘要：
Based on NaSch model, energy consumption in the mixed traffic flow was investigated. The formula of energy consumption was presented. There are three factors of mixed traffic flow to be studied, which are the maximum velocity, length of vehicle, and the ratio of the mixed traffic flow （ Cn ）, respectively. Simulation and analysis indicated that the energy consumption of the mixed traffic flow consisting of vehicles of the same length but different maximum velocity is associated with the lowest maximum velocity and its ratio. The slower the maximum velocity and its fraction, the more energy tttconsumed. Moreover, for the mixed traffic flow consisting of vehicles with the same maximum velocity bot different length, the energy consumption is related to the ratio Cn of mixed vehicles. Longer vehicles lead to more energy consumption. For the mixed traffic flow involing vehicles of different maximum velocity and lengths, its energy consumption is determined by the ratio Cn of the mixed vehicles and delay probability p, the more the short and fast vehicles（ Cn→0）, the ess energy consumed, and vice versa.
