As was the case in 2017, and as part of the evolution of the Panel Survey, there were some changes to the demographic and trip diary components, in addition to recruiting efforts, to better reflect the City’s priorities. [...] The objectives of the Panel Survey are to: 1) Assess the travel mode share and number of trips for nine transportation zones in the City; 2) Assess the average VKT by City residents; and 3) Determine factors that have contributed to changes in travel behaviour and travel patterns. [...] The inaugural 2013 Panel Survey established a benchmark of travel behaviour in the City, against which the following panel surveys are compared, allowing the City to capture trends in the key parameters of total trips, mode share, and VKT. [...] These trade-offs generally involve the following key considerations: Frequency of Measurement The infrequent nature of the Census Journey to Work and the Regional Trip Diary reduce the ability to measure the impacts of local and regional initiatives as multiple changes may occur between surveys. [...] As the Panel Survey is conducted annually, this provides the City of Vancouver the opportunity to perform a detailed analysis to determine the correlation and possible causation of changes to travel behaviour and patterns.
