Assessment of Alternatives in Roadside Vegetation Management

This research will identify a set of factors that should be considered when determining the best practice for maintaining vegetation at the pavement edge on a given roadside. A number of known alternative methods exist for maintaining vegetation at the edge of highway pavement, each with a unique relationship to decision factors identified as part of the best practices determined above. The project will identify costs, benefits, and relevance of decision factors. A decision framework shall be developed for use by maintenance managers and design engineers to help determine the best alternative for maintaining vegetation at the pavement edge in a given location. In such a decision framework, specific roadway, shoulder, and roadside parameters would be entered. The proejct will also develop a field validation methodology for the decision framework. Various roadside locations will be identified at which long-term monitoring will take place in relation to the alternative methods and cost/benefit measurements generated by the decision framework.
