摘　　要：交通分区是交通调查、规划的空间单元,以往的分区往往是单一体系,为了同时满足交通调查、规划解释的需要。笔者发现,分区的面积、几何形状均可能对预计的出行距离、空间分布产生较明显的影响,为此总结了三条规律。研究工作在假设、虚拟城市的基础上,靠实验计算而得到结论,国外学者针对现实城市、区域的研究结果和笔者提出的某些规律基本相似。在此基础上,笔者又提出了交通分区的理想目标和三项原则,再进一步提出调查小区、分析小区、规划管理或解释小区三者相对分离、相互转换的办法,既可满足三项原则,又可适应实际工作中调查、分析、解释的不同需要。Traffic Analysis Zone （TAZ） is an important spatial unit system for traffic survey and transportation planning. TAZ is often a single system and suitable for surveying and explaining at same time. It is found that different area and geometric shapes of zones will notably affect the forecast results of trip distance and distribution. There are three laws for that. This paper is based on laboratory analysis using hypothetical cities. Some literatures for real cities and regions are also similar to the above three laws indirectly. Three principles for ideal TAZ are put forward in this paper. Surveying zones, calculation zones and explanation zones can be relatively independent and transformed each other by Geographic Information Systems technology. Different types of zones could be suitable to different needs in survey- ing, calculation and explanation.
