Transportation Needs and Issues Survey (2007) - Summary Report:Summary rept

摘要

The Transportation Needs and Issues Survey was conducted in October and November of 2006 by the Survey Research Center at Oregon State University. The survey used a random digit dialing telephone survey method and completed a total of 1,013 interviews. The random sample was stratified by ODOT Region and contained at least 200 completed interviews per region. The statewide data was weighted to reflect the different population sizes within each region, household non-response by region, the variable number of landlines within a household, the number of adults in the household, and population characteristics of gender, age, and race/ethnicity.
