When transit and mobility options are inaccessible or don’t meet needs, people find ways to travel. For most of the world, this often takes the form of informal transit services. As a result of failed public investment in transportation, these flexible, low cost, and unregulated systems are often the main form of travel in developing countries. Although higher income countries have some forms of informal transport, it is often subsidized and more regulated microtransit. These more flexible options do not replace formal transportation networks, but they do provide a critical service to often overlooked communities.
