Abstract
The invention discloses a plotting method for a three-dimensional time-space diagram showing a regional green-wave coordinated control effect. The plotting method includes the following steps: establishing a coordinate system of the three-dimensional time-space diagram; determining a specific position coordinate of each intersection in the coordinate system of the three-dimensional time-space diagram; generating a time prism of a signal timing plan of each intersection; determining a green-wave bandwidth of each arterial road; and generating a driving trajectory between the intersections, and making a green-wave band of each arterial road, and completing plotting.
