摘要
交通运输系统规划的主要内容是对区域和城市运输系统进行预测和优化研究,它是交通GIS应用的重点领域。结合交通地理信息系统的基本概念,利用T-GIS进行发生与吸引交通量的预测是交通运输规划与GIS相结合的主要应用分支之一。以西安市为例,在TRANSCAD环境下进行交通发生量与吸引量的建模和预测,得到了直观、可靠的结果,可见T-GIS技术在交通领域具有广阔的应用前景。
The transportation system plan which is the main field of the applications of T-GIS aims to
predict and optimize the local or urban traffic system. Based on the fundamental conceptions of T-GIS,prediction for trip generation and attraction was one of main applications between traffic plan and GIS.Procedures how to establish models with TRANSCAD software with example in Xi＇an are illustrated and ultimately attained a satisfied result. T-GIS has wide applications in traffic and transportation.
