Abstract:

This TechBrief discusses how complex interchanges with multiple exit lanes, including an option lane, can be confusing to navigate. Roadway signs provide navigational, lane assignment, and roadway geometry information that explain complex interchanges to drivers. Well-designed roadway signs help drivers make timely and accurate decisions. Signs that are confusing or that violate driver expectations may lead to unnecessary lane changes, sudden lane changes, and mistakes that may compromise roadway system efficiency and driver safety.
