Abstract:In the express reconstruction of urban roads, some small traffic light intersections will often be changed into the right-in and right-out intersections, and the rigid traffic demand of residents along the line will need to take the form of turn around. Therefore, the setting of turnaround intersection is more important. The front and rear traffic lights can be used to turn around, and the turnaround intersection can be set in the road section. And the air turn lane can be also set in the road section if permitted. By studying the relative situation of setting the turnaround intersection in the road section, the design strategies of turnaround are put forward. The relevant case analysis is given. It is hoped to provide some useful reference for solving the problem of vehicle turnaround in the express reconstruction of urban roads.
