TRAVEL BEHAVIOR SURVEY DATA COLLECTION INSTRUMENTS

Abstract

There exists a tremendous variety in the structure and form of instruments to collect household travel data. The basis for most instruments was the in-home interview used in the 1950s and 1960s. Current instruments reflect changes in data collection methods, from in-home to mailback or telephone retrieval. The amount and type of information desired to be collected have also changed with the requirements of new legislation and the underlying transportation planning and forecasting models. Current issues in household travel survey instrumentation are discussed, including the pros and cons of various approaches, and recommendations for future practice are presented.
