    Two-Phase Sampling Method of Resident Trip

      摘要
    • 摘要: 针对大城市居民出行调查抽样问题,运用数理统计学原理分析了分层抽样的特点,基于二重抽样理论,建立了改进后的分层抽样模型,推导了基于最优分配的二重分层抽样率公式,并使用实际调查数据对分层方法进行了讨论,结论表明,该模型既保持了分层抽样数据精度较高的特点,又节约了大量人力物力,建议在特大城市开展居民出行调查时采用这种方法.

       

      Abstract: To solve problems in the sampling process of resident trip investigation,this paper applied mathe- matical statistics to studying the characteristics of stratified sampling method.A two-phase stratified sampling method and stratified principls have been discussed.The result shows that this method can save more man- power resources while keeping high investigation precision.It is suggested that two phase sampling method should be adopted in metropolitan area.
