摘要
为了减少抽样调查费用,提出了一种基于交通调查费用的交通分层抽样容量确定方法,分析了该方法应用于实际交通起讫点调查,并以某区域的居民出行起讫点调查为例,说明交通调查层次划分及抽样数目,实现系统优化。
In order to reduce sampling survey expenses,this paper presents a method of determining the traffic stratified sampling capacity based on traffic survey cost,analyses its applicatiion in the practical origin-destination survey,and illustrates by the example of origin-destination survey of the residents in a district the stratification and sampling amounts of traffic survey,so as to accomplish the system optimization.
