In addition to public health guidelines, active transportation has several concepts that should be pursued in parallel. The first concept is multimodality in transportation, which means that people use multiple modes of transportation during a trip, such as walking, cycling, public transportation, with shared mobility services such as bike sharing or car sharing, or other modes for different parts of their trip. Therefore, there is the need to create integrated and interconnected transportation systems that encourage individuals to incorporate physical activity into their daily routines while also reducing their reliance on motorised transportation. The second concept is walkability and cyclability, which refers to the quality of the walking or cycling environment and its ability to support and encourage active transportation. The third concept is individuals’ capabilities and opportunities to access and use active transportation modes (ie, accessibility). Accessibility consists of several dimensions, including social, economic, skills-related, physical, temporal, spatial, informational, legal-organisational, mental, and cultural dimensions.
