DEVELOPMENT OF A MICRO-COMPUTER AIDED TRANSPORTATION PLANNING SYSTEM

过去几年出现的方法，特别是在公交路线规划的背景下，是使用交互式图形来实现规划者和基于计算机的规划方法之间的直接对话，具有实时图形或非图形响应。它允许规划者通过使用他熟悉的术语来参与计划过程，并且避免了数据处理任务。一旦建立了数据库，规划者就不需要知道或关心计算机编程或计算机系统的技术细节。它还允许即时可视化输入数据、计算结果和从数据库检索的信息，所有这些都以图形或列表的形式出现。本文开发的系统是一种交互式的多模式城市交通规划方法。它比目前已开发的其他交互式图形方法更全面。在这里开发的系统中可以输入、修改和用于计算的数据主要分为三类：网络、矩阵和函数。网络数据可以通过本系统的网络编辑器进行录入、修改和显示，但遗憾的是，目前还不能配备这种编辑器。该系统数据库的矩阵可以输入、修改和显示，并且可以使用矩阵编辑器执行各种矩阵计算。该系统数据库的所有相关功能都是通过函数编辑器输入和评估的。

The approach that has emerged over the past few years, particularly in the context of the transit route planning, is to use interactive graphics to enable direct dialog, with real-time graphic or nongraphic response, between the planner and the computer-based planning method. It allows the planner to engage in the planning process by using the terminology that he is familiar with and obviates data-processing tasks. Once the data base is set up, the planner need not know or be concerned with the technical details of computer programming or computer systems. It also permits the instantaneous visualization of input data, results of computations, and information retrieved from the data base, all in graphic or list form. The system developed here is a multimode urban transportation planning method designed for interactive use. It is more comprehensive than other interactive graphic methods that have been developed to date.The data that may be entered, modified, and used for calculations in the system developed here fall into three main categories: networks matrices, and functions. The network data may be input, modified, and displayed by using the network editor of this system, but unfortunately this editor can not be equipped for the present. The matrices of this system data base may be entered, modified, and displayed and various matrix calculations may be performed by using the matrix editor. All relevant functions of this system data base are entered and evaluated by using the function editor.
