SAMPLING PLAN FOR THE CONNECTICUT STATEWIDE HOUSEHOLD TRAVEL SURVEY

This report which documents the development of alternative sampling plans for application in a proposed statewide household travel survey, documents the objectives of the proposed survey, presents the sample sizes for estimating important survey levels of precision, evaluates alternative strategies for selecting survey sample sizes, and illustrates the use of statistical sampling procedures and previously collected travel survey data to design a new travel survey. A simple random sample of households will be selected within each town class to measure variables of interest. The general formula is presented for estimating the minimum sample size of estimate the average number of person trips of purpose per household at a desired level of precision. Person trip generation rates by type of household and town class are also covered. The two major sources of data used to calculate sample sizes for the proposed statewide household travel survey were the 1964 Connecticut statewide household travel survey data files, and the fourth court census data from 1970. Sample size estimates are presented which illustrate the minimum number of household samples requires to estimate statewide travel characteristics when there are no geographic and socioeconomic stratifications of households or trip purpose stratifications.
