The Baltimore Travel Survey, 1977, is a comprehensive collection of demographic characteristics and travel patterns for 967 households in Baltimore, Maryland. The survey was conducted in May and June of 1977; survey results have been maintained and distributed by the United States Federal Highway Administration. Survey participants were asked to provide detailed household information, including length of residency at current address, number of household occupants, type of dwelling unit, number of vehicles available to household occupants, and the body type of each vehicle. Respondents were also asked to provide information on their travel behavior during a 24-hour assessment period, including trip duration and frequency, trip purpose, departure and arrival times, mode of transportation, number of passengers, and parking cost. Demographic information for this collection includes age, sex, disability, race, spoken language, marital status, income, and educational attainment.

The original data deposit for this collection contained several variable discrepancies that could not be resolved. Therefore, this collection has been minimally processed by ICPSR.

The depositor has indicated that from the variable "cell" onward, the data was not digitized correctly for the majority of entries. Please see the Original P.I. Documentation section of the ICPSR Codebook for additional information regarding these errors.

2013-08-20 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Checked for undocumented or out-of-range codes.

The data contain a weight variable (HHWEIGHT) that may be used for expanding the sample. Derived from the sampling rate within the household's stratum, the weight corrects for non-randomness in the sample selection process. For additional information, please see the Original P.I. Documentation section of the ICPSR Codebook.
