"基于JSP的城市公交线路查询系统设计与实现"

ublic transportation passenger information system is at a relatively backward level of development, and the majority of passengers have limited ways to access information. In order to address this issue, it is necessary to vigorously develop urban public transportation passenger information systems in China. With this goal in mind, under the guidance of a teacher, I have designed the Changchun public transportation route query system. This article describes the development of the Changchun public transportation route query system using JSP, applying principles of software engineering and utilizing object-oriented programming. The development process includes establishing and maintaining a backend database and developing a frontend application, achieving automation and informatization of public transportation queries. The entire system is designed to meet requirements of ease of operation, user-friendly interface, flexibility, practicality, and security. It completes tasks such as inputting public transportation route information and querying this information. Through practical testing, it has been proven that the public transportation query information system designed in this article can meet the needs of public transportation information queries. Furthermore, considering the psychological characteristics of public transportation passengers and factors that influence their route choices, a model for selecting public transportation routes based on time value and cost value has been established. Based on this model, the framework design of the key parts of the program is carried out to clarify the program design ideas. Subsequently, the specific implementation of the key parts of the program, including the original code, is provided. Finally, the article successfully introduces the system's functions and provides instructions for use. Keywords: public transportation query, route decision-making, SqlServer database.
