Research On Dynamic Scheduling Of Single Bus Based On Time Varying Data

With the development of China’s economy,the process of urbanization has been accelerating and the amount of motor vehicle has increased at an alarming rate.Traffic congestion has become a key issue in restricting urban development.The development of public transport has brought new ideas to solve the problem of traffic congestion.Improve the level of public transport services to increase the attractiveness of public transport,public transport is an important research area.In recent years,the Internet technology has matured development,intelligent bus research in the field ushered in a new opportunity,data collection front-end equipment and basic hardware facilities update iteration,into the era of large data,how to collect and process effective information,through real-time feedback,make up The lack of traditional static bus scheduling,real-time dynamic scheduling of public transport vehicles to become a new breakthrough in the field of intelligent bus research.Papers from the basic principle of dynamic transit operation and basic strategy,explore the analysis of current transit operation development,summarizes the intelligent bus dispatch advantages compared with traditional bus scheduling,the intelligent transport system at home and abroad,especially the theoretical research of intelligent bus scheduling a detailed literature review,this paper discusses the current research focus and research of scholars both at home and abroad,and established the single line of thought for studying the dynamic scheduling,this paper explore research innovations,the research of intelligent bus dispatch.The basic theory of single dynamic transit operation,this paper analyzes the main factors affecting the dynamic scheduling test execution.Based on different dynamic scheduling strategy of comparing the advantages and disadvantages,choose dynamic jump station scheduling for this article main research direction,and studied the dynamic scheduling modeling idea mainly reviews,represented by genetic algorithm(GA)group of bionic algorithm in the study of dynamic scheduling of obvious advantages,so in this paper,based on genetic algorithm(ga)algorithm to construct the direction,improve the scientific nature and rationality of scheduling policy.And then the article analyses the single line dynamic scheduling system,the characteristics of passenger flow and vehicle,thus raises two key problems of the single line dynamic scheduling,explores the transit passenger flow and bus operation information of data acquisition and data processing,passenger flow of bus IC card data as the main data source,bus GPS data as the main source of vehicle information,through the analysis of data and information,for the establishment of the single line bus dynamic scheduling model provides data foundation,expansion of the bus IC card data sample model is put forward,to ensure the reliability of data,based on the short-term prediction,constructs the dynamic departure schedule,cost and operator to passengers as the goal to build a single jump line dynamic scheduling model,and through the genetic algorithm model for the implementation.Finally,the article through to the rizhao city bus group obtain bus data,selecting 19 road bus routes data used to build model algorithm to carry on the simulation of the single line bus dynamic dispatching measures,and through the cost analysis and evaluation of the effectiveness of the proposed model,this article research conclusion.
