Research Of Static Bus Transfer Query System Based On Java

In recent years, with the development of economy, science technology, people’s living standard has improved greatly, and the urban construction and the industry is rapidly developing. As people’s living standards improve, more and more people go to the city, and there are more and more private cars, but the resulting problems are becoming more and more outstanding. Now in the big cities, because the car is much, every day will appear different degree of congestion. In addition, according to a study, car emissions is several times higher than the usual when the jams. In order to solve the road congestion and reduce the pollution brought by car, we have to push forward the way of the bus travel. Due to the complexity of urban road conditions and the variety of bus line, it is not easy to choose the appropriate transfer plans for people. In order to solve these problems, studying out a practical and efficient public transport transfer algorithm is very important.Paper first analyzes the domestic and foreign researchers for people’s travel habits related problems such as study, according to the results of the analysis put forward the least time, the least walk, the least transfer time and the least cost, the four different kinds of transfer model. Then, we research the domestic and foreign existing public transport transfer algorithm and put forward our own algorithm design dividing into static transfer algorithm and the analysis of bus data. Among them, the static part transfer algorithm by processing the data of bus stations, stops and lines gets direct solution and the walking solution between the stations, then according to the direct solution we can generate multiple transfer plans; Besides part of data mining analysis of bus operating data, we get the bus stop time, the driving time and each bus departure intervals, through these data, we can correct the time of transfer solution, to make transfer plans more accurat. After generating the bus transfer plans, in order to plan vividly displayed, we set up a transfer plans query system base on B/S structure, using the open source framework Spring and Struts2. Next, the thesis also test the the system accuracy, coverage and the system response time. And the test results show that the bus transfer algorithm this paper proposed meet the user requirements of four transfer model, also has high accuracy, high coverage, and high query efficiency. Finally, the paper describes the weakness of the current system and possible improvement methods, and summarizes the author working content and study results during the period of graduate students.
