This revised guide is a result of field testing during 1984-85 as part of an evaluative study to determine the ease or difficulty in using this step-by-step approach. Following years of research by the Michigan Department of Transportation (MDOT), this guide addresses safety versus environmental issues. Survey forms, text format, and descriptive sections have been revised to attain a more practical document. A method to identify and treat both existing and potential locations having a higher risk of vehicle/tree accidents is included, along with a methodology to be more responsive to conditions and accident frequencies specific to local and State jurisdictions. Information is included to identify and evaluate higher risk roadside environments, and to provide guidance for implementing roadside tree removal and for addressing environmental issues, alternative treatments, mitigation, and maintenance practices.95
