Development of a Comprehensive Access Management Policy and Guidelines- Phase 1: State-of-the-Practice Review, Data Assessment, and Work Plan Development

The proposed research project will expand upon previous studies and provide comprehensive guidance as to access management strategies that are appropriate across various road types and geographic settings in consideration of important local factors. This guidance will be developed on the basis of a quantitative risk assessment that relates crash rates to traffic volumes and access management strategies. The results of this analysis will help to inform development of a revised access management policy, as well as associated guidelines that assist the Iowa Department of Transportation in implementing consistent, research-based guidance as a part of its continuing access management program.
