This article evaluates the livability of residential boulevards, a type of street that has center lanes for through traffic and local access lanes separated from the center lanes by landscaped “malls.” Three boulevards were studied. All three carried high traffic volumes but were rated as more livable than neigh- boring, conventionally designed streets with medium traffic volumes. The study concludes that boulevards with a side median design successfully mitigate the adverse impacts of heavy traffic. The re- search methods used for this study were based on the well-known 1969 “Livable Streets” project by Donald Appleyard and Mark Lintell. Like the original study, it compared the re- sponses of residents on streets with high, medium, and low traffic volumes and measured the effects of traffic on social interaction, perceptions of home territory, and the comfort of peo- ple’s daily lives. The new study shows trends similar to those found in the original one and adds information about boulevards, which were not pre- viously examined.

Streets have become dangerous, unlivable environments, yet most people live on them. Streets need to be redefined as sanctuaries; as livable places; as communities; as resident territory; as places for play, greenery, and local history. Neighborhoods should be protected, though not to the point of being exclusionary. The neighborhood unit, the environmental area and the Woonerf are examined as models for the protected neighborhood. The criteria for a protected neighborhood depend on acceptable speeds, volumes, noise levels, reduction of accidents, and rights-of-way for pedestrians.
