Trees Make Streets Safer

Ithaca, NY (September 2006)- Proposals for planting rows of trees along the roads- a traditional technique for shaping pleasing public spaces- are often opposed by transportation engineers, who contend that a wide travel corridor, free of obstacles, is needed to protect the lives of errant motorists.
Increasingly, however, the engineers’ beliefs about safety are being subjected to empiracal study and are being found incorrect. Eric Dumbaugh, an assistant professor of transportation at Texas A&M, threw down the gauntlet with a long, carefully argued article, “Safe Streets, Livable Streets,” in the Summer 2005 issues of the Journal of the American Planning Association.
