Our project quantified the impact of changes in travel mode shift and trip distance on active and non-active transportation of an adult population from São Paulo, Brazil. It showed that the replacement of individual for collective motorized modes in long trips (>1000m) plus the substitution of long for short trips could positively impact all outcomes, with great potential for health promotion.
Changes in urban mobility play a major role in transforming metropolitan areas into healthier places. This study quantified the impact of changes in travel mode shift and trip distance on active and non-active transportation of working age adult population of São Paulo.
Methods and Findings
Through different scenarios, we estimated the daily time spent in transportation per inhabitant (divided in active and non-active transportation time) and the proportion of inhabitants accumulating 30 minutes or more of daily active transportation. The replacement of individual for collective motorized modes in long distance trips (> 1000m) in combination with the substitution of long for short trips positively impacted all outcomes. Compared to the current situation, there was an increase in the active transportation time (from 19.4 to 26.7 min/inhabitant), which also increased the proportion of adults active for transportation (from 27.6% to 35.4%). Additionally, the non-active transportation time decreased (from 67.0 to 26.2 min/inhabitant), which helped to reduce the total time spent in transportation (from 86.4 to 52.9 min/inhabitant).
Transport and urban planning policies to reduce individual motorized trips and the number of long trips might produce important health benefits, both by increasing population levels of active transportation and reducing the non-active and the total time of daily trips.
