One of the Transitway's major features will be a pedestrian mall in the shopping area located between Fifth and Sixth Avenues, where only buses will be allowed on 34th Street. Yet similar malls across the country have failed. These include State Street in Chicago, Brattle Street in Cambridge, Washington Boulevard in Detroit and K Street in Sacramento. In these cases, cities have restored traffic to make the streets safer and more retail-friendly. On retail streets, people prefer a lively mix of shoppers and vehicles rather than big open spaces where they feel alone and vulnerable. And people mean more retail activity, higher commercial rents and increased revenues for cities.
