摘要： 交通运输能源消耗已经成为决策管理者高度关注的信息。采用元胞自动机（CA）理论研究了快速公交系统能耗问题,以元胞自动机NaSch交通流模型为基础,通过结合动能定理,建立了快速公交系统的元胞自动机能耗动力学仿真模型。并以目前建设的兰州市快速公交系统为例,仿真研究了周期性边界条件下,不同行车密度、不同停靠站时间以及驾驶员行为差异下随机慢化对快速公交车系统能耗的影响,得到了相应的定量分析结论。仿真结果表明,快速公交车辆停靠站时间越长,拥堵的范围越大,路面交通流能耗损失越小,对应的流量、速度也越小,系统越早进入堵塞相。

Abstract: Transportation energy consumption has aroused high attention of the decision-makers. In this case, an energy consumption of Bus Rapid Transit (BRT) Cellular Automata (CA) model was designed, which was based on NaSch traffic model and Kinetic energy theorem. Taking Lanzhou city bus rapid transit traffic system as an example, the effects of BRT vehicle random slowness in the different traffic density, different road condition and drivers' behavior under periodic boundary conditions was studied. And corresponding quantitative analysis conclusion was get. The simulation results show that the rapid transit vehicle stops longer, the greater the range of congestion and the smaller the energy loss of the road traffic flow. Besides, the corresponding flow rate is also smaller, thus the system is plugged into congestion phase earlier.

Key words: Cellular Automata (CA), Bus Rapid Transit (BRT), traffic flow, energy consumption
