[0065] specific implementation plan
[0066] we take figure 1 Take the road as an example to illustrate the situation of a parallel left turn at an intersection.
[0067] Figure 1 The basic parameters of the intersection are as follows: the width of the two-way four-lane road is 18 meters. Among them, the one-way 2 motor vehicle lanes are 3.25 meters * 2, and the non-motor vehicle lanes are 2.5 meters. The widening section on the outside of the exit is the outer left lane, about 60 meters long, and the middle lane of the entrance is the inner left turn area, about 80 meters long. The buffer zone between the two parking lines is 40 meters, the front part is 25 meters as the parking area, and the rear part is 15 meters as the U-turn area; the widening section at the entrance is about 120 meters long, and the sections are used as bus stops and entry and exit lanes (48 meters in total), U-turn waiting area (24 meters), U-turn lane 15 meters, right-turn parking area 25 meters,...
