A review of factors and benefits of non-motorized transport: a way forward for developing countries

Non-motorized transport (NMT) is the use of a bicycle or walking to travel from one place to another. It is gaining popularity especially in the developed countries due to low transport externalities such as emissions and traffic congestion alongside its benefits to physical and mental health. In this paper, a comprehensive review of the existing literature related to NMT is presented focusing on the factors including built environment, geography, and weather, the health, and environmental benefits of NMT, and the motivational approach for increasing the use of NMT. The built environment, geography and weather, and socioeconomic factors significantly affect the use of NMT as a travel mode. This study reviewed some unique characteristics of NMT especially in developing countries to provide a clear understanding of the dynamics of NMT. Despite existence of vast research on NMT, a comprehensive literature review to evaluate different aspects of NMT seems essential to address the future challenges with significant automobile ownership increase in the developing nations and the associated externalities. The developing nations have to understand the factors of NMT with reference to their socio-economic conditions and perform quantitative analyses to estimate and project benefits of NMT including health benefits. The policy makers in the developing countries should consider the NMT as one element of the solution matrix to address the challenges of road transport.

Automated summary

Non-motorized transport (NMT) involves using bicycles or walking to travel and is affected by factors such as built environment, geography, weather, and socioeconomic conditions. Developing countries have unique characteristics in NMT which should be understood for addressing future challenges and considering NMT as part of the solution for road transport issues.
