Three sampling techniques for calibrating disaggregate travel demands models are considered: random, stratified, and choice-based sampling. In a random sample, the probability of all members of the population being in the sample is equal; in a stratified sample, the population is divided into groups based on one or more characteristics and each group is sampled randomly but a different rates; and in a choice-based sample, the number in the sample selecting each alternative is predetermined, i. e. , the sample is based on the outcome of a behavioral choice process.
