Abstract—In order to reduce road fatalities as much as possible, this paper presents a new method in evaluation of road geometric design consistency based on speed and safety in rural highways. The consistency model presented in this paper is based on the consideration of continuous operating speed profiles. Geometric design consistency studies can be used to identify inconsistent sections on highways, which can then be targeted for improvement. No geometric data exists for rural highways. A method of estimating geometric data from digital maps was implemented on some kilometer of highways. Elements were classified as good, fair or poor using a design evaluation criterion. A geometric design evaluation can be used to indicate locations on highways where accidents occur more. Improvement works can be concentrated on the sections and hence rural highways can be made safer.
