Optimization Research On Urban Bus Line Network Based On Shared Bicycle Track

Nowadays,with the continuous development of information technology and urbanization accelerating,"Shared cycling+"way of slow transportation developing rapidly,and it also makes urban residents travel more convenient,but how to realize the optimization of urban transit network on the basis of urban public transport data,has become a problem of urban public traffic management.At the same time,this problem is also a research hotspot in the field of urban public transportation.Therefore,based on the analysis of Shared bicycle tracks,this paper studies the optimization of urban bus network,so as to meet the travel demands of urban residents and maximize the benefits of urban bus operating enterprises,thus,alleviate the supply-demand conflict between urban residents and urban bus operating enterprises.Combined with trajectory data processing and urban bus network planning theory,first,this paper analyzes the characteristics and relationship between Shared cycle trajectory and urban bus network.On this basis,the preprocessing schemes of Shared bicycle track and urban bus network data are determined respectively,and the candidate data sets are formed respectively.Then a fusion scheme is constructed to realize the abstract representation and fusion of multi-source data.Secondly,based on the analysis of the optimization principle of urban bus network and the influencing factors of the optimization objective,the reasonable optimization objective is selected,and the optimization model of the minimum passenger travel time and the minimum operation cost of urban bus line is constructed.At the same time,an improved tabu search algorithm is designed to solve the problem.Finally,taking Beijing public transportation as the research object,the data of Beijing bus network were obtained through Beijing bus network,Gaode map API interface and other channels,and the cycling data of Beijing residents in the 2017 Mobike Cup Algorithm Challenge was analyzed.The results show that the proposed model and its solution can meet the practical needs of the optimization of bus network in Beijing.Above all,in this paper,design scheme presented,the urban transit network optimization model and algorithm provides a new way of thinking for the study of urban transit network optimization,and also provides a reference for the research of the urban transit network optimization based on Shared cycling track,meanwhile,it will be able to provide good decision support for managers of the urban public transport planning institutions,which optimize urban transit network scientifically.Under the background of advocating green transportation,urban residents further recognize the travel mode of "Shared bicycle+urban bus",which improves the travel efficiency of residents and the green and low-carbon urban public transportation system.
