For many, informal transportation is a normal part of everyday life. It is highly visible on the streets of cities across the Global South, but remains much less visible in mainstream mobility and transportation practice, investment, and policy.  Too often the world of informal transport is viewed as a problem to be solved. Yet, informal transport provides us a window into how people want and need to move. Through a set of specific learning questions we want to explore the potential of this important sector and eventually, we hope, showcase the opportunities that exist to provide better mobility for all. This inception report presents the preliminary analysis conducted through a desk review and interview with experts to answer the six learning questions on informal economies provided by the UNDP Accelerator Lab team.
