Transportation for the 21st Century Household Travel Survey (Philadelphia, 2000)

Household travel surveys such as the Transportation for the 21st Century Household Travel Survey (Philadelphia 2000) are used to obtain information about work and non-work trip generation, trip distribution, modal choice, and traffic assignment as well as to obtain data on average vehicle occupancy. The study area for this travel survey consisted of the Pennsylvania counties of Bucks, Chester, Delaware, Montgomery, and Philadelphia (along with a small portion of Berks County); the New Jersey Delaware Valley counties of Burlington, Camden, Gloucester, and Mercer; and the South Jersey counties of Atlantic, Cape May, Cumberland, and Salem. The resultant data set contains demographic and travel data on 5,677 households in the 14-county study area. Of the 5,677 households that participated in the study, 2,666 were from the Delaware Valley region of Pennsylvania, 1,551 were from the Delaware Valley region of New Jersey, and 1,460 were from Southern Jersey. The Transportation for the 21st Century study relied on the willingness of area residents to complete diary records of all travel for a 24-hour period. It was based on telephone interviews of randomly selected households from the 14-county study area. Participating households were assigned a specific "travel day" or 24-hour period on which to record their travel and activities. Demographic variables include the number of vehicles in the household, household income, age, gender, whether respondents held a valid driver's license, whether respondents had a disability, and employment status.
