Lane departure is a major cause of side-swipes, rear-end collisions, and crashes. Road curvature, as an important part of linear road design, plays a vital role in lane departure. Based on study of the Curve radius and slope of the road, the linear parameters can be optimized to reduce the probability of lane departure. The curvature radius and slope of the road are designed in UC-winRoad and multiple experiments through a driving simulator are performed to output the evaluation data. Based on the radius of curve, slope, and turning direction, numerical analysis of the lane offset are proposed. The relationship between lane departure and road alignment is obtained by analyzing the |P1| value after fitting the vehicle trajectory. The study found that the right-turn curves have a larger lane departure than the left-turn curves, and that too small and too large a curve radius will result in a large lane departure.
