| By developing public transport to solve city traffic problems has formed a broad consensus.Public transport system of city bus system connect on a layer of rail transit system and the important function of the next layer of slow system,its operation plays a key role to alleviate urban traffic problem.And in order to better play to the role of the public transport system,need to develop scientific and rational bus operation plan.In this paper,based on the background of bus operation plan optimization problems were studied.Given the limitations of traditional public transport planning and optimization to solve the complexity of conventional modeling and simulation technology to solve the problem of randomness and uncertainty has advantages,so this study adopts the method of system simulation to study and solve the problem of public transport operation plan optimization.First of all,introduce the system modeling and simulation theory in this paper,and establish a unified dimension both passengers interests and benefits the optimization model of the bus company.Then,in the comprehensive investigation and analysis of the public transport system on the basis of the actual operation process,the abstract and simplify the complicated transport system,get the conceptual model,based on the simulation process and the overall structure,then the simulation model was built based on ExtendSim simulation software simulation module and database,data collection,statistics and processing module,and use the simulation optimization module previously established optimization model is constructed.Secondly,from the angle of traffic engineering,according to the people,vehicles,line,pipe system from four aspects analyzes the public transport planning and optimization to the basis of information acquisition and processing.Through field research in shizuishan dawukou,collected the data related aspects and processing;According to the basic principle of BP neural network,hop on and off the bus stops rush hour number prediction model is set up.Finally,combining with the instance,input in the simulation model based data acquisition and processed,run the simulation and analysis the simulation results,got in dawukou 1 road bus peak departure interval and car project,solve the problem of public transport operation plan optimization.This paper established the simulation optimization model under the condition of the data updated regularly,can be in dawukou 1 road bus operation plans for continued to compile and update,at the same time,on the basis of input data and parameters,can be applied to the other city bus lines. |
