Latin American population is almost 80% urban
LA has 4 cities over 10 M hab, 50 over 1M and 150 over 0,5M
Streets are estimated to represent between 25 and 30 % of urban surface
They are the privileged space of encounter, interaction, economic activity and social integration of the city
However, not enough attention is being paid to their design, management and governance

How to achieve best/balanced street performance remains an open question.
