Roadway design is one of the most significant factors that affect driving behavior and perceived safety. The current study tests the combined effects of three roadway design elements - shoulders width, guardrail existence and roadway geometry (curvature) - on objective driving measures (speed and lane position), and subjective measures (perceived safe driving speed and estimated road safety). Twenty two drivers participated in an experiment with a driving simulation. In the first part objective… CONTINUE READING
