摘要
我国城市公交换乘信息系统的发展处于一个较落后的水平,广大乘客可以获得信息的方式很少,为了解决这种问题,需要大力发展我国的城市公交乘客信息系统。出于这个目的,在老师的指导下,我设计了这个城市公交出行线路换乘查询系统的应用程序。
在设计过程中,首先分析了我国城市公交乘客信息系统的发展现状,找出问题和不足。其次,在对公交乘客出行心理特征进行分析的基础上,考虑了乘客选择公交线路决策的因素,建立了基于换乘次数的公交线路选择合理的模型。在此基础上,进行程序关键部分的框架设计,理清程序设计思路。之后是程序关键部分的具体实现,包括关键程序源代码。最后完成功能介绍和使用说明。运用VISUAL BASIC开发工具,对天津市的部分线路查询系统进行了程序设计, 并进行了模拟实验。本次设计的软件较为符合公交运营的实际情况,充分考虑了不同公交乘客的实际要求,运算速度较快,有较强的实际应用价值。

The public transportation transfers the referral system paper [资料来源:http://THINK58.com]
ABSTRACT [资料来源:THINK58.com]
Our country city public transportation transfers information systems development to be in a backward level, the general passengers may obtain the information the way to be very few, to solve this kind of problem, needs to develop our countrys urban public transportation passenger information system vigorously. Stemming from this goal, under teachers instruction, I designed this urban public transportation journey line to transfer referral systems application procedure.
In the design process, has first analyzed our country city public transportation passenger information systems development present situation, discovers the question and the insufficiency. Next, in goes on a journey the psychological feature to the public transportation passenger to carry on the analysis in the foundation, had considered the passenger chooses the public transportation line decision-making the factor, established based on has transferred the number of times the public transportation line choice reasonable model. Based on this, carries on the procedure essential part the frame design, clears off the programming mentality. Afterward is procedure essential part concrete realization, including essential procedure source code. Finally completes the function introduction and the operating instructions. Using VISUAL the BASIC development kit, has carried on the programming to Tianjins partial line referral system, and has carried on the modelling. This designs software tallies with the public transportation operation actual situation, had considered fully the different public transportation passengers actual request, the operating speed is quick, has the strong practical application value.
