Abstract: In order to update the basic transport database and obtain an in-depth understanding of the travel demands and patterns in Beijing, a series of transport and traffic surveys have been undertaken by the government. The household interview survey (HIS) is the most important undertaking with sample size over 80,000 households. Because of complexity and limitation in various stages of the surveys, errors and under-reporting are inevitable. Therefore, results of sample data and sample expansion can not reflect the real travel characteristics. This paper introduces the data expansion and validation process of Beijing household interview survey data. Errors and under-reporting were eliminated by a series of processes, such as sample expansion, matrix estimation, independent data checking and comprehensive validation.
