Abstract
Street layout is consistently associated with adults' travel behaviors, however factors influencing this association are unclear. We examined associations of street layout with travel behaviors: walking for transport (WT) and car use; and, the extent to which these relationships may be accounted for by availability of local destinations. A 24-h travel diary was completed in 2009 by 16,345 adult participants of the South-East Queensland Household Travel Survey, Australia. Three travel-behavior outcomes were derived: any home-based WT; over 30 min of home-based WT; and, over 60 min of car use. For street layout, a space syntax measure of street integration was calculated for each Statistical Area 1 (SA1, the smallest geographic unit in Australia). An objective measure of availability of destinations – Walk Score – was also derived for each SA1. Logistic regression examined associ-ations of street layout with travel behaviors. Mediation analyses examined to what extent availability of destina-tions explained the associations. Street integration was significantly associated with travel behaviors. Each one-decile increment in street integra-tion was associated with an 18% (95%CI: 1.15, 1.21) higher odds of any home-based WT; a 10% (95%CI: 1.06, 1.15) higher odds of over 30 min of home-based WT; and a 5% (95%CI: 0.94, 0.96) lower odds of using a car over 60 min. Local destinations partially mediated the effects of street layout on travel behaviors. Well-connected street layout contributes to active travel partially through availability of more local destinations. Urban design strategies need to address street layout and destinations to promote active travel among residents.
