Dr Clemence Cavoli (CTS, UCL) Introduces T-SUM

18 March 2019 

Dr Clemence Cavoli introduces the T-SUM (Transitions to Sustainable Urban Mobility) project, an interdisciplinary and cross-sector collaborative project that aims to identify the conditions under which sustainable and inclusive transport and land use development can be accelerated in growing cities in the Global South.


It is grounded in the observation that where there is still-low-but-rising levels of motorization, economic growth and increasing social and spatial inequalities, the formulation and implementation of policies, practices and partnerships that can support an accelerated implementation of sustainable mobility structures is an urgent concern for rapidly developing cities.

This project will initially focus on Maputo, Mozambique, and Freetown, Sierra Leone, as apposite examples of growing urban economies in Sub-Saharan Africa and other parts of the Global South.


T-SUM is a cross-departmental collaboration between UCL Development Planning Unit at the Bartlett (Prof Caren Levy, Co-Investigator; and Dr Oviedo, Co-Investigator) and the Centre for Transport Studies, part of CEGE (Professor Jones, Principle Investigator; and Dr Cavoli, Co-Investigator and project manager). It involves a range of partners in Maputo and Freetown, including academics, consultants and policy-makers and institutions such as the World Bank and UN-Habitat. The project was born after the UCL team was awarded a seed grant in a competition funded by the UCL Grand Challenge for Sustainable Cities and the UCL Institute for Transport.
