Mobile Internet-based Support System Of Subway Travel Research And Design

With China’s rapid economic development and rapid urbanization, the urban population continues to grow in number and density of urban subway has become more and more important, people use the subway traffic travel fast increasing demands. Mobile intelligent terminal real-time access to public transport information and mobile payment has become a hot demand for travel costs, based on this, the paper mobile Internet core technologies and Intelligent Transportation depth theoretical research and exploration, and research and design a more intelligent, information-based metro traffic travel aids. The main work includes the following aspects.(1) On the background and significance of this paper briefly describes and briefly introduces the basic situation of domestic subway travel, the Internet + transport, the shortest path algorithm and short-term forecasting passenger traffic theory.(2) Describes analytical techniques subway travel auxiliary systems involved, including Android development technology(mobile client systems to Android-based system), HTML5 technology(used to draw the subway map), two-dimensional code subway electronic ticket technology(systems in the form of two-dimensional code), the development of mobile payment technology(Alipay development and micro-channel pay development), these technologies are mature and efficient.(3) To achieve system electronic fare calculation and line transfer guidelines, study the shortest path problem, mainly graph theory and search theory(DFS, BFS) and the common knowledge of the shortest path algorithm, and use Dijkstra algorithm to achieve the idea of an electronic ticket price calculations and line transfer guidelines.(4) To achieve subway passenger information dissemination, research the subway passenger short-term forecasting methods, introduced short-term traffic flow prediction methods commonly used(linear and nonlinear methods), and according to the characteristics of subway passenger(cyclical volatility), made with gray Markov model to achieve.(5) This article focuses on the design and implementation of subway travel auxiliary systems, including the structure of the entire system(network design, database design), subway lines and site information display, two-dimensional code in the form of underground electronic ticket, the electronic ticket mobile payments, real-time and future subway traffic congestion publish, subway transfer guidelines(the shortest path can be combined with traffic congestion) part of the design and implementation.ITS is the future trend of development of the transportation system to achieve intelligent traffic information system is a major issue in the field of transport, metro areas in the country rapidly developing herein do intelligent information to try to improve it for the majority of the metro situation, to enhance the traveler experience of great help, but also hope to traffic in other areas(such as highway, etc.) to bring inspiration.
