transCAD简单教程

一、概况

TransCAD系统是由美国Caliper公司开发的交通GIS软件，现已推出用于Windows平台的3.5版。

二、技术特性

TransCAD软件把地理信息技术和交通规划技术较好地结合在一起，可以方便地对各类交通运输及相关数据进行存储、提取、分析和可视化。由于采用先进的Windows环境及一系列最新的开发方法，使得软件具有较好的风格：先进的菜单界面、强大的图形功能、方便的工具栏、良好的开放性、多文档、多用户操作等等。

TransCAD与其它Windows应用程序相仿，对容量没有硬性限制，最大限度地发挥硬件能力。运行环境为Windows 3.1及以上版本。TransCAD 3.5为32位应用程序。

三、功能特性

TransCAD主要包括5大功能：

∙Windows下的、功能强大的地理信息系统；

∙扩展数据模型，提供显示和处理交通数据的基本工具；

∙汇集了极其丰富的交通分析过程；

∙各式各样、数量巨大的交通、地理、人口统计数据；

∙可以生成宏、嵌入、服务器应用及其他用户程序。

交通过程主要包括：

∙网络和路径：生成、设置、路段方向、选定路段、转向工具箱、最短路、多路径、货郎担问题、网络分割、带宽设定等

∙线路系统：线路服务、站点服务、线路编辑等

∙规划：出行产生、吸引、平衡、快速反应模型、出行分布、交通分配等

∙公交：网络生成、设置、最短路、网络阻抗计算等

∙路线和逻辑分析：成本矩阵计算、货运路线计算与显示、弧最短路、指派问题、运输问题、货流配送、最小成本流、分区、聚类、设施定位等

统计：报表、校正、模型估计、模型应用、生成模型文件、邻接矩阵、空间校准等TRANSCAD教程1-- Project and TransCAD Overview

ORGANIZATION

LAB OBJECTIVES

To provide hands-on experience with transport planning, analysis, and design and t o present Geographical Information Systems (GIS) fundamentals.

TERM PROJECT

Homework assignments and the course project will utilize TransCAD, a PC-based GIS for transportation which is installed in the Civil Engineering Computer Lab in E G3141. A formal lab will be held every week; typically on Fridays but occasionally on Mondays and Wednesdays (a discussion section often may be held as part of t he lab). Individual copies of TransCAD are not available, but additional formal lab ti me will be scheduled as needed. TransCAD manuals will be available in the Lab, and may be checked out from the TA or the main CEE office. The course project will be completed individually (or perhaps in teams of 2). There will be intermediate reports due during the quarter, and a comprehensive final report will be due durin g exam week (tentatively, June 16, 2004). Incorporated into the final report will be one or more network design solutions. It is highly recommended that each person/t eam keep all project material in a 3-ring binder to facilitate management of project

documentation. All project reports must be prepared professionally. Given the import ance of technical writing in the Civil Engineering profession, each submitted project will receive two equally weighted grades: one for technical content, one for report quality. Formal report preparation guidelines are included in the course notes. Sam ple projects from prior years are available from the instructor or TA.

GRADING

Lab works will account for 35% (30% on term project and 5% on unannounced qui zzes in lab) of the total course grade.

INTRODUCTION

What is TransCAD?

TransCAD is a full-featured Geographic Information System (GIS) designed specific ally for managing analyzing, and presenting data related to transportation systems and facilities. It contains a comprehensive set of transportation analysis models that are commonly used by transportation professionals in their daily work.

What is a GIS?

Different definitions of a GIS have been used in different disciplines. For the newco mers to GIS, consider this relatively simpler definition: A computer software designe
