URBAN TRAFFIC CALMING MEASURES - CONFORMANCE WITH AASHTO AND MUTCD GUIDELINES

A review of traffic calming measures is conducted to evaluate implementation and construction considerations within the U.S. urban roadway and street system. Criteria for roadway design and traffic operations in the U.S. are primarily established through two pivotal resource documents, "A Policy on Geometric Design of Highways and Streets" published by the American Association of State Highway and Transportation Officials (AASHTO) and the "Manual on Uniform Traffic Control Devices" (MUTCD) published by the Federal Highway Administration. Traditionally, both of these publications have focused more significantly on motor vehicle facilities and traffic safety. Prior to the implementation of wide scale use of traffic calming measures in the U.S., specific treatments must be critically evaluated against established national criteria and design guidelines.
