Public-bike Multi-objective Programming Model And Development Strategy Research Under The Influence Of Free-floating Bike-sharing System

With the rapid development of urbanization and motorization,a series of problems is increasingly severe,such as traffic congestion,environmental pollution,travel costs,public health.At present,the public generally believe that public transportation development is the effective way to solve the problem of urban traffic.However,the rail transit and the ground public transportation are unable to meet the demand of ‘the last kilometer’ at the end of the traffic,greatly limiting the overall efficiency of the public transport system.In this case,the public bicycle system developed,which can provide "door to door" of travel services.But since the end of 2016,all kinds of free-floating bike-sharing systems rely on the advantages of mobile phone scan code,rent or park a bike at any time,mobile phone positioning and smart unlock,rapidly seizing the user market.The public bicycles that have risen earlier have experienced different degrees of "cooling down" in various places.But with the rising of shared bicycles,Public bike operation benefits gradually decline,bring a certain degree of loss to the government and the company.Therefore,it is particularly important to study the development of public bicycles under the influence of shared bicycles.This paper uses RP and SP survey techniques to investigate the use of public bicycles and shared bicycles in Xi’an.The study found that public bicycles in Xi’an lacking attractiveness to younger groups,lacking attraction for flexible travel needs,and prominent inconvenience in accessibility.And it has been found that the two modes of transportation,public bicycles and shared bicycles,are not completely homogenous competition,but there are certain complementary relationships.In order to further quantify the impact of shared bicycles on public bicycles,this paper establishes a multi-objective planning model.Then,using the hierarchical sequence method to obtain optimal solution gradually.Finally,taking the public bicycle in Xi’an as an example,the parameters of the three-level objective function are solved using the survey data and related operational data,and analyzing the results of the model.The study found that although the emergence of shared bicycles has led to declining public bicycles usages,the variables such as the satisfaction of public bicycle users,the government’s social utility,and the level of services provided by enterprises have shown an increasing trend.However,public bicycles usages are not the lower the better.The declining usages are accompanied by a reduction in corporate profits and a decrease in user satisfaction(usage is less than 1.8 times per vehicle per day).It is difficult for public bicycle companies to maintain normal operations.Therefore,public bicycle companies need to formulate development strategies adapted to the development trends of the two modes of transportation in order to adapt to fierce market competition.This article uses the SWOT-AHP analysis method to formulate a growth-oriented strategy to adapt to the development of public bicycles in Xi’an,and giving concrete implement plans.
