This article describes the multistage sampling system employed in the 1996 national roadside survey and compares it to the sampling methods employed in the two prior surveys in 1973 and 1986. Also described are the data collection procedures at the selected sites, the breath-test devices used to collect blood alcohol concentration (BAC) data, and the methods used to impute BAC values where breath-test measures were not obtained. Overall, almost twice as many (6,298 in 1996 compared to 3,698 in 1973 and 3,043 in 1986) drivers were interviewed in the most recent national survey as in the previous efforts. The procedures implemented in the three surveys are sufficiently similar to permit comparison of these surveys conducted at 10-year intervals.
本文介绍了1996年全国路边调查所采用的多阶段抽样系统，并将其与1973年和1986年之前两次调查所采用的抽样方法进行了比较。文中还描述了在选定地点的数据收集程序、用于收集血液酒精浓度（BAC）数据的呼气测试设备，以及在未获得呼气测试结果时用于估算BAC值的方法。总体而言，在最近一次全国调查中接受访谈的司机数量（1996年为6298人，而1973年为3698人，1986年为3043人）几乎是前几次调查的两倍。这三次调查所实施的程序足够相似，以便能够对每隔10年进行的这些调查进行比较。
