A Review of the Factors Influencing the Tendency to Walk More in Daily Trips

Nowadays, transportation is an essential requirement for citizens, which causes many traffic and health problems. According to several problems rising by motorized vehicle usage, transportation planners are trying to persuade people to use active transportation modes such as walking. Therefore, it is crucial to investigate the effective factors on walking behavior. This paper reviews the effective factors on the tendency of citizens to walk more on their daily trips. Studies showed that there are four main effective factors including socio-economic characteristics (e.g., gender, age, income, and vehicle car ownership), trip characteristics (e.g., distance, and time of trip), environmental factors (e.g., density, diversity, design, destination accessibility, and distance to transit), and subjective factors (e.g., attitudes, and perceptions). According to the literature, this paper shows that environmental and subjective factors are the most effective. Therefore, it could be suggested that planners consider these two factors simultaneously in their policymaking. Further investigations depict a research gap in walking studies that suggest researchers can concentrate on different trip purposes by considering the above-mentioned factors simultaneously, especially in developing countries.
