A variety of intersection control evaluation processes and metrics are used by highway agencies for evaluating intersection geometry and control options 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.
NCHRP Web-Only Document 377: Background and Development of a Guide for Intersection Control Evaluation, from TRB's National Cooperative Highway Research Program, documents the initial development and evolution of the guidance for developing an ICE process that is presented in NCHRP Research Report 1087: Intersection Control Evaluation: A Guide.
