Energy consumption of bus rapid transit system based on cellular automata theory

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.
