Longitudinal evaluation of travel and health outcomes in relation to new bicycle infrastructure, Sydney, Australia

Abstract

Abstract Background This study sought to evaluate the health and transport impacts of urban bicycle infrastructure for transport through a commuting corridor in Sydney, Australia. Methods An online survey and seven-day travel diary collected health and travel data from intervention area residents, and residents of a control area with similar characteristics and distance from the city, at baseline (n = 846), and follow-up, four months (wave 2; n = 512) and 16 months (wave 3; n = 418) post-construction. Multilevel regression modelling was used to compare changes over time with distance from the cycleway. Results In wave 3 24.5% of the intervention group reported using the new cycleway. Residents who started using the cycleway predominantly lived within 1 km of the cycleway (62%); however 13% of users in wave 3 lived more than 3 km from the cycleway. Frequent cycling (weekly) was strongly associated with use of the cycleway (p Conclusions Cycling participation has been decreasing in Sydney and Australia in recent years; however, urban bicycle transport infrastructure can have a positive impact on cycling, particularly urban cycling for transport, and has the potential to improve health and transport outcomes for city residents.
