The design of urban road intersections is crucial to improve the vehicle operation at intersections, reduce conflict points, and reduce energy consumption to maximize the rational use of limited resources. Facing the increasingly severe road environment, it is imperative to make more reasonable planning and design intersections. According to the road planning and design steps, first of all, determine the number of lanes, slope, design speed, turning radius and complete the road cross-section design according to the road grade and urban population cross-section design. At the same time, count the number of motor vehicles, non-motor vehicles and pedestrians. After that, timing calculation, saturation calculation and delay calculation are carried out to complete the timing scheme of single point intersection signal light. At the same time, the road plane shape is designed, the size of diversion island is calculated, the intersection plan is obtained, and the intersection contour distribution map is obtained according to the slope calculation for elevation drawing.
