本文提出了一个用于微型计算机的城市交通咨询系统,即使不懂计算机语言的用户也能容易地使用这一系统找到一条到达目的地的路线;该系统已用于天津市;程序用 FORTRAN 和 dBASEⅢ分别写成;这一系统已在 IBM PC—XT 和长城0520上实现.本软件的所有提示都使用了中文,操作容易,查询迅速.查询中使用了递推算法.数据与程序彼此独立,其它城市如果想使用仅需修改数据文件而不必修改程序。软件结构清楚,移植和扩充容易。它是一个实用的软件。 This paper presents an urban traffic advisory system for microcomputers that can be easily used by users without computer language to find a route to their destination; the system has been used in Tianjin; the program uses FORTRAN and dBASE III Respectively, written in; The system has been implemented on the IBM PC-XT and the Great Wall 0520. All tips of this software are used in Chinese, easy to operate, fast query.Retrieval algorithm used in the query.Data and program independent of each other, other cities If you want to use only need to modify the data file without having to modify the program. Software structure is clear, easy to transplant and expand. It is a practical software.
