| Abstract | This paper describes sampling concepts and techniques that can be used to design household travel surveys for statewide transportation planning. Emphasis is placed on defining survey objectives in terms of the level of presision desired in estimating key variables. The need to incorporate cluster sampling treatments for trip-related variables collected in household surveys is introduced and discussed. Detailed procedures are presented for computing the minimum sample sizes of household interviews needed to accomplish survey objectives at minimum cost. A simplified method is described to account for losses in precision becasue of clustering. Application of the sampling techniques to an actual state travel survey design illustrates the influence of alterative levels of precision and data stratification on survey sample size. The applicability of these sampling concepts to other areas of transportation planning is discussed. |
