Junction Designs Examples and Improvements in Junction Designs

Abstract

Junction design and application principles are very important because traffic accidents occur mostly at junctions. Insufficient infrastructure and driver errors constitute a significant part of accidents. In this study, two junction designs in the 11th Regional Directorate of Highways and the 16th Regional Directorate of Highways on the at-grade junction, which is one of the highway junction designs, were examined. The improvements made in the design of these junctions are examined. By using satellite images of roads, junction designs were made with the help of the Microstation inroads program. The findings obtained because of the study were evaluated and suggestions were presented.
