This report discusses geometric design consistency, particularly for rural roads. It presents rules on geometric design consistency suitable for use in an expert system such as the Interactive Highway Safety Design Model (IHSDM). The rules can also be used directly by a designer to evaluate roadway designs or to conduct reviews of existing roadways, improving design consistency and safety.
