Guide For Intersection Control Evaluation

Guide for Intersection Control Evaluation

"A variety of intersection control evaluation processes and metrics are used by highway agencies for evaluating intersection geometry and control alternatives and identifying an optimal geometric and control solution for an intersection. These processes usually address safety, operational, multimodal, environmental, right-of-way, and cost impacts and other considerations. However, there is no widely accepted procedure or guide for evaluating new intersections or modifications to an intersection. There is a need to develop a guide that incorporates rational processes, objective performance metrics, and appropriate tools to provide a consistent and objective intersection control evaluation. Such a guide will help highway agency personnel in making decisions regarding intersection type and control, and implementing safer, more balanced, and more cost-effective solutions. The objective of this research was to develop a guide for intersection (including interchanges) control evaluation. The guide is accompanied by associated processes and tools to facilitate implementation." -- publisher's website
