Rapidly-urbanizing emerging markets are increasingly experiencing transportation-related challenges ranging from congestion to air pollution to social inequality.  At the same time, the rise of mobile technology and the increasing role of enterpreneurship has lead to a boom in new mobility innovations that are changing the face of a traditionally highly-regulated industry.  This master's project team sought to develop an understanding of what promotes and inhibits successful entrepreneurial ventures in the new mobility space and how these factors vary across different geographies.  The team focused on case studies from Brazil, China, India, and South Africa.  Based on its findings, the team developed a resource to help entrepreneurs start and grow new mobility ventures that create environmental and social improvements by leveraging mobile phone and internet technologies.
