The primary objective of TransLink’s regularly conducted Regional Trip Diaries is to obtain information on 24-hour weekday travel from a random sample of local residents. The 2011 Regional Trip Diary survey used a combination of online and mail-out questionnaire options and was conducted from September 15th to December 12th, 2011. The study area includes Metro Vancouver, and stretches beyond to encompass the entire Lower Mainland, from Lions Bay to the Fraser Valley Regional District and all the way to Hope.
