ارزش قائل شدن برای سفر فعال: از جمله مزایای بهداشت و درمان حمل و نقل پایدار در چارچوب های ارزیابی حمل و نقل

Sustainable transport investments linked to improving public transport or designed specifically to improve walking and cycling networks (for example, bicycle infrastructure) typically underestimate the contribution of these active travel modes. This is because the investment appraisal mechanism, social cost benefit analysis, lacks an agreed methodology or well defined parameter values for establishing the demand and the associated health benefits and costs of active travel. Correcting for the acknowledged benefits of walking and cycling (including contributions to achieving physical activity targets and maintaining health) requires an appropriate framework and parameter values to allow these benefits to be captured in a robust and consistent manner. This paper proposes such a framework for the Australian context and a consequent weighted benefit of $1.68 per km (range $1.23–$2.50) for walking and a $1.12 per km (range $0.82–$1.67) for cycling that includes both mortality and morbidity changes resulting from a more active lifestyle. Investigation of the potential health costs associated with motorised travel and reduced physical activity requires further detailed research.
