Expanding Bicycle Infrastructure to Promote Physical Activity in Hidalgo County, Texas

Abstract BackgroundCycling for transport provides many health and social benefits – including physical activity and independent access to jobs, education, social opportunities, health care and other services (accessibility). However, inequalities exist for some population groups in the opportunity to reach everyday destinations, and public transport stops, by bicycle – owing in part to their greater aversion to riding in amongst motor vehicle traffic. Health equity can therefore be improved by providing separated cycleway networks that give people the opportunity to access places by bicycle using traffic-free routes. The aim of this study was to assess the health equity benefits of two bicycle infrastructure development scenarios – a single cycleway, and a complete network of cycleways – by examining the distribution of physical activity and accessibility benefits across gender, age and income groups.MethodsTravel survey data collected from residents in Sydney (Australia) were used to train a predictive transport mode choice model, which was then used to forecast the impact of the two scenarios on transport mode choice, physical activity and accessibility. Accessibility was measured using a utility-based accessibility measure derived from the mode choice model. The distribution of forecast physical activity and accessibility benefits was then calculated across gender, age and income groups.ResultsThe modelled physical activity and accessibility measures improve in both intervention scenarios. However, in the single cycleway scenario, the benefits are greatest for the male, high-income and older age groups. In the complete network scenario, the benefits are more equally distributed. Forecast increases in cycling time are largely offset by decreases in walking time – though the latter is typically low-intensity physical activity, which confers a lesser health benefit than moderate-intensity cycling.ConclusionsSeparated cycleway infrastructure can be used to improve health equity by providing greater opportunities for transport cycling in population groups more averse to riding amongst motor vehicle traffic. Disparities in the opportunity to access services and economic/social activities by bicycle – and incorporate more physical activity into everyday travel – could be addressed with connected, traffic-free cycleway networks that cater to people of all genders, ages and incomes.
