Transportation systems have traditionally been designed for traffic mobility and driver safety. New research suggests that urban road projects could safely accommodate more trees than are currently allowed in transportation building codes. “In my opinion, the transportation policy in regard to trees is based on outdated information,” said Kathleen Wolf, a social sciences researcher at the University of Washington’s College of Forest Resources and lead author of the study.
Context Sensitive Design is a new approach in transportation planning that recognizes community values. Roadside vegetation and green spaces are often valued features of transportation corridors. The studies below are investigations of public values regarding trees and vegetation in urban vehicular use areas.
