Study On Influence Of Transportation In Urban Public Transport Networks With Bicycle Sharing Systems

As the urbanization process increase rapidly,the problem of urban traffic jam become a pressing matter of the moment.As a healthy and environment-friendly trip mode,public bicycle-sharing systems,which have so far been built in hundreds of cities around the world,have been developing rapidly recently.The PBSS,which are usually spatially embedded where original urban public transport networks are located,comprise the new urban public transport system together with the urban public transport network.Therefore,studying the impact of bicycle sharing systems on the original urban public transport networks is an important research subject.Base on the model of multi-layer coupled networks and real data of urban public transport networks,the research of the paper invoice impact of bicycle sharing system on urban public transport networks,structural controllability in complex network and its application.The major goals are as follows:(1)The impact of a public bicycle-sharing system on urban public transport networks.Using the real spatial location data of public bicycle-sharing systems of Hangzhou and Ningbo in China,we propose a multi-layer coupling spatial network model that considers the geographical information on bus stations,bus routes,and public bicycle stations by studying the urban public transport networks.The spatial network model consists of bus subnets,short-distance bicycle subnets and short-distance walk networks that are interdependent rather than independent.We apply the model to study the influence of bicycling between the short-distance bicycle station pairs and walking between the short-distance bus station pairs on the performance of urban public transport networks.(2)The collocation method of bicycle-sharing system in the light of the structural controllability in complex networks.Based on the theory of the structural controllability in complex networks and the model of multi-layer coupled network of urban transport networks,we design the collocation method for bicycle-sharing systems to find the amount and locations of specific bicycle stations.After comparing with existing bicycle-sharing system collocation conditions by using some performance indicators,we prove their reasonability for future application.(3)Designing and developing a mobile system in public transport service which is based on the augmented reality(AR)and bicycle-sharing systems embedding multi-model public transportation transfer.The system can offer the function of searching routes considering public bicycle-sharing systems and find bus stations nearby by using of mobile cameras,which is in the light of the technique of the augmented reality.It can provide users who go out with positive user experience so that encourage people to choose green trips more feasibly.The study aims to solve the problem in urban transport based on the real data of cities public transport system and bicycle-sharing systems.To make results reasonable,we not only study the impact of bicycle-sharing systems on urban transport networks but also design and develop methods to improve the urban transport condition.Although it may be far from comprehensive,we would improve the existing problems in the future step by step.
