Design And Implementation Of Public Transport Inquiring System

There is broad consensus on preferentially developing urban public traffic. It can not only solve the problem of urban traffic jam but also bring far-reach influence on energy saving and environmental protection.In spite of the rapid economic development in China, poor public transport and management means have bring stern challenges to our country's traffic management work. At present, it is impossible for our country to spend a large amount of money on road construction, which will improve the "hardware" environment of urban traffic. Therefore, based on the scientific and technological process, developing intelligent traffic management system is an effective way of realizing traffic informatization with less input and quick returns.Nowadays there're many inquiry systems of public transport, which contain some defects such as slow and inaccurate data updating. Based on the research and analysis on these defects, a new system named Public Transport Inquiry System has been designed and developed in this paper. The new ideas in this paper are as follows:1. According to the analysis and study on domestic public transport information, this inquiry system includes many functions such as public transport route inquiry, site inquiry and station-to-station inquiry after the data structure construction of public transport information.2. Improve the transfer algorithm on the basis of profound research on station-to station inquiry which is the most important function in public transport system, the research results of public transit transfer, and the influence of transfer factors on passengers.3. The inquiry results can be obtained faster with the help of cache technology because we can use bisearch algorithm which improves the inquiry speed.4. The public transit information can be received by these two ways. On one hand, we can extract the information by net-spider. On the other hand, the information supplied by net friends is also helpful. The public transport information can be updated rapidly by the way of manual examination after the analysis of the information.5. By the popular architecture of foreground display of PHP language and background statistics of Java language, the inquiry system can show automatic input prompts in public transport information.6. This paper also contains the application of 3G in public transport inquiry system in the future.
