North America Needs a New Model for Pedestrian-Friendly Planning
The city of Buenos Aires has transformed a 20-lane congested highway into an 80-block multi-modal downtown avenue with dedicated bus lanes, plenty of space for walkers, and green space. Daily commute times have been cut in half for 200,000 bus passengers. Car access to these renovated streets is limited to local residents with parking passes. The speed limit for local car traffic is 10 km.
The Sustainable Mobility Plan for the city of nearly 3 million residents and 4 million commuters and tourists "rethinks the value and use of public spaces for citizens, not simply as areas reserved for transport services and connections, but as areas of mobility for citizens," according to the state's website.
Robert Everett-Green argues that similar attempts to pedestrianize streets in Canada have failed because they assumed that only highly commercial/retail zones would be appropriate for pedestrianization. A look at the Buenos Aires experience immediately exposes the weakness of most North American attempts at pedestrianization: that they are too narrowly focused on a few blocks of one street, with little thought given to the broader ecology of public space and transport," he writes. The head of transportation in Buenos Aires, Guillermo Dietrich "says the city was not swayed by the conventional wisdom that pedestrian zones only work in strong retail and nightlife zones," according to Everett-Green.
Everett-Green points out that pedestrian-only zones–such as a four-block stretch of Ottawa's Sparks Street–are too limited in scope. Adding planter boxes to a small zone where more than half the streetscape is populated by public works buildings is an insufficient strategy for appealing to pedestrians, he writes. In contrast, another 20 blocks are planned for the pedestrian-friendly zone on Avenida 9 de Julio in Buenos Aires, and spaces formerly used by parking lots are being repurposed for retail and residential development, suggesting that transit innovation can spur mixed use development.
