Washington Post Poll: DC-Region Traffic Poll, January 2005 (ICPSR 4316)

Principal Investigator(s): The Washington Post


This special topic poll, fielded January 27-31, 2005, was undertaken to assess public opinion on traffic congestion in the Washington, DC, area. Respondents who commuted in the greater Washington, DC, area were asked about traffic conditions in the region, their primary means of transportation to and from work, the length of their commute, what they liked and disliked most about their commute, and whether they had ever relocated or adjusted their work schedule to improve their commute. Those polled rated the different types of public transportation available in the area, how often they used the Metrorail subway system, and why they did not ride it more often. Views were sought on proposals to expand the Metrorail system and build new highways in the area, sources of funding for transportation projects, and whether measures such as high occupancy vehicle lanes, adjustable tolls, and building new roads were effective in easing traffic congestion. Respondents were also asked about the type of vehicle they drove, how often they traveled by car, how much time they spent driving, and how often driving invoked feelings such as independence, relaxation, and anger. A series of questions asked respondents how often they and others were guilty of behaviors such as speeding or road rage, and whether they engaged in activities such as eating or reading while driving. Additional topics addressed the use of automatic cameras at traffic lights and stop signs and whether existing traffic laws were too tough on teenage drivers. Demographic variables included sex, age, race, household income, education level, and political party affiliation.

Data Type(s):    survey data

Data Collection Notes:

(1) The data available for download are not weighted, and users will need to weight the data prior to analysis. (2) Additional information about sampling, interviewing, and sampling error may be found in the codebook. (3) Original reports using these data may be found via the Washington Post Opinion Surveys and Polls Web site. (4) System-missing values were recoded to -1. (5) The FIPS variable was recoded for confidentiality. (6) Value labels for unknown codes were added in the variable MSA. (7) According to the data collection instrument, code 3 in the variable Q909 also included respondents who answered that they had attended a technical school. (8) The CASEID variable was created for use with online analysis.


Sample:    Households were selected by random-digit dialing. Within households, the respondent selected was the adult living in the household who last had a birthday and who was home at the time of the interview.

Weight:    The data contain a weight variable (WEIGHT) that should be used in analyzing the data. The data were weighted using demographic information from the Census to adjust for sampling and non-sampling deviations from population values. Respondents customarily were classified into one of 48 cells based on age, race, sex, and education. Weights were assigned so the proportion in each of these 48 cells matched the actual population proportion according to the Census Bureau's most recent Current Population Survey.

Mode of Data Collection:    telephone interview

Extent of Processing:   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:

  • Created online analysis version with question text.
