For this purpose, under the guidance of teachers, I designed this city bus trip circuit system application. In the design process are analyzed, the first Chinese city bus passenger information system development present situation, problems and the insufficiency. Secondly, in the transit passengers psychological characteristics on the basis of the analysis of the passenger choice, consider the factors, decision bus routes were established based on the value of time and the cost value bus lines reasonably select the model. On this basis, a key part of the design process, a framework of design. Is a key part of the program after implementation, including the key process original code. Finally complete function and use. Using VB language or method of lines, the program design system, and the simulation experiments. The design of the software to conform to the actual situation, full consideration of the actual requirements of different bus passengers, the operation is fast and strong p
