Abstract
BackgroundThis study estimated the modal shift associated with the implementation of a public bicycle share program in Montreal, Canada.MethodsA population-based sample of adults participated in two cross sectional telephone surveys. Self-reported travel behaviors were collected at the end of the first (fall 2009) and second (fall 2010) season of implementation. The sample included 2502 (Mean age=47.8 years, 61.8% female), and 2509 (Mean age=48.9 years, 59.0% female) adult respondents in each survey.ResultsThe estimated modal shift associated with the implementation of the PBSP from motor vehicle use to walking, cycling, and public transportation was 6483 and 8023 trips in 2009 and 2010. This change represents 0.34% and 0.43% of all motor vehicle trips in Montreal.ConclusionsThe implementation of a PBSP was associated with a shift toward active transportation. The modal shift was complex and not simply the result of a discrete shift from one mode to another. Promotion of active transportation should encourage integration of multiple active transportation modes to better reflect people’s actual transportation behaviors.
Highlights
This study estimated the modal shift associated with the implementation of a public bicycle share program in Montreal, Canada
Numerous studies show that greater use of motor vehicles at the population level is associated with negative health consequences including injuries and death due to collisions [5,6], exposure to air pollution [7], and lower levels of physical activity [8]
Public health interventions that promote a modal shift from motor vehicle use to active forms of transportation can simultaneously influence multiple health outcomes, including physical activity, injuries and exposure to air pollution [15]
Summary
The aim of this study was to estimate the modal shift from motor vehicles to active transportation associated with the implementation of the PBSP program in Montreal
