The NHTS would also allow the household travel within the Baltimore region to be compared to similar urban areas across the country, since all survey data and add-ons are collected in a similar fashion. The travel survey also coincided with the 2000 decennial Census, another large database used by local planners. The Baltimore Regional Transportation Board felt the survey was a unique opportunity to collect household travel observations that could assist in developing travel models used in policy analysis and development of long range transportation plans. Study Purpose View help for Study Purpose A smaller weekend sample was selected to start the process of understanding the travel choices being made and to establish a baseline to measure change.ĭemographic variables include the respondent's age, sex, employment status, occupation, education level, household income, place of birth, relationship to the reference person, whether the respondent is a licensed driver, and whether respondents have a medical condition. Recently, non-work related travel has rivaled commuting with some locations in the Baltimore region having the greatest one hour peak volume on weekends. Traditionally, travel activity has been focused on weekday travel associated with commuting as a primary concern. A smaller survey of 325 households was also sampled to obtain weekend travel behavior. The household survey was mainly focused on weekday travel, collecting a one day travel itinerary from 3,131 Baltimore region households.

The Baltimore Regional Transportation Board (BRTB), the designated MPO for the Baltimore metropolitan area, agreed to participate in the 2001 National Household Travel Survey (NHTS) as an add-on. The USDOT allows states, local jurisdictions and Metropolitan Planning Organizations (MPO) to purchase additional local samples. Approximately every 5 years, the United States Department of Transportation (USDOT) conducts a national household survey that is used to measure demographic and household travel characteristics used to evaluate national policies and assist researchers in understanding emerging travel trends.
