REVOLUCION DIGITAL Transformaciones Políticas, Sociales y Culturales Street: the ultimate urban public space Andrés Borthagaray Institut pour la ville en mouvement Consejo de planeamiento estratégico, Buenos Aires SEMINARIO NACIONAL DE PRESUPUESTO PUBLICO
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 UN HABITAT WORLD URBAN FORUM 6th THE URBAN FUTURE
Oken exchan Some pedestrian streets survived since colonial times, still vital with commerce. Sunlight is essential. Some others, in car dominated cities, were established as welcome exceptions. Still, monofunctional streets as a rule sacrifice diversity. And sometimes they were offered as a compensation for less pedestrian space in other streets. How to achieve best/balanced street performance remains an open question.
Peatonales Livable pedestrian streets in Buenos Aires and Lima
Streets are the place for many vital urban functions, they structure cities above ground they contain buildings, commerce, open views vehicle (all kind of vehicles, 4, 2 wheels) and pedestrian movement, articulate public and private space, (where windows and doors from private open) greenery, drainage underground they carry subway, utilities, pipelines. UN HABITAT WORLD URBAN FORUM 6th THE URBAN FUTURE
Streets are the place for many vital urban functions:
Paseo de la Reforma, México City Monumentality A successful integration of vegetation
Población Vital streets in popular neighborhoods: the most frequent example, sometimes ignored in social housing or urban planning
Funcionalistas Everything sacrificed to car circulation (twice)
Avenida Jiménez, Bogotá, Colombia A balanced integration of mass transit and landscaped public pedestrian space. The physical environment helped to recover social and economic activity.
BRT funcionalista Curitiba, a pioneer in BRT, tied transportation to land use and density. Others took only the most visible part, regardless of different environments
Social improvement through street space redesign in a modest neighborhood (Patio Bonito, Bogotá). A solution reached through a participative planning process
A parallelism: Narrow economic measurement GDP reductionism and human development/happiness Narrow street design concepts Traffic engineering reductionism and urban performance of the street How to widen the criteria for designing, managing and governing the street? Buchanan put the concept in crisis, but it still remains rather dominant BRT is not one type fits all situations The view from the bus: the legible city. UN HABITAT WORLD URBAN FORUM 6th THE URBAN FUTURE
By offering wider references to professionals of the built environment, decision makers and community leaders School books and professional guides too often mirror the narrow approach New options are needed to frame a better debate for our urban future. That is our challenge.
