Everyday mobility practices are increasingly an element of interest for urban policy, as well as for suggesting alternative solutions to urban issues. Amongst their manifold contributions, practices can be relevant for securing individuals' access to places and opportunities. They can do so by promoting services and behaviours based on resources that individuals may share between themselves. This role could be significant especially for those settings where the traditional provision of transport services and infrastructures is more difficult, such as in the informal settlements of the urban South. Drawing on these assumption, this paper intends to investigate policy solutions based on mobility practices, as a suitable way to enhance the access to urban opportunities from informal settlements. Policy approaches focused on mobility supply and demand are explored, addressing options such as the coproduction of mobility services and behavioural approaches based on demand matchmaking. A possible operationalization of such approaches is explored in the marginal informal neighbourhoods of Bogotá, considering their accessibility issues, how shared use mobility policies may tackle them, and what features are necessary for the implementation of such measures. The proposed policy measures emerge as suitable operational options that nonetheless require recognition and support by the institutions responsible for urban mobility planning.
