A Systematic Literature Review on Health Benefits, Incentives, and Applications to Promote Walking in Urban Areas

The transportation sector contributes significantly to global warming, as well as to urban fabric problems such as traffic congestion, traffic accidents, noise pollution, and air pollution. A shift from fossil fuels to renewable sources and from motorized to non-motorized modes is now considered essential to create sustainable communities. Walking is a sustainable transport mode and several studies have focused on factors affecting it, including travel behavior and sociodemographics. In this study, we conduct a systematic literature review to identify and record walking benefits, the financial incentives that encourage travelers to walk, and applications that support it. Financial incentives are found to have short-term effects, and their success depends on the level and structure of the incentives as well as the characteristics of the participants. In addition, non-financial incentives, such as improving infrastructure and pedestrian safety, or providing information and education about the benefits of walking, may also promote it as a main mode of transport.
