Intersection channelization simulation method and intersection channelization simulation device

Abstract

The invention discloses an intersection channelization simulation method and an intersection channelization simulation device. The method comprises the following steps: acquiring feature information of an intersection road sent by a client, according to the characteristic information of the road and the center point coordinate of the intersection; determining the values of the characteristic points of the road channelization, traversing the values of the characteristic points of each road, taking the right far-end point of the current road as a starting point, connecting the characteristic points of each road through a curve and a straight line, drawing the outline of the intersection, drawing the lane, the lane sign and the sidewalk of each road of the intersection, and sending the drawnchannelization information of the intersection to the client. The method comprises the following steps: receiving feature information sent by a client; determining the value of the feature point of each road. The feature points of the intersection are obtained, then the contours of all the roads are drawn according to the values of the characteristic points, so that channelization information of the intersection is drawn and processed, the channelization precision of the intersection can be improved through client display, a mechanism associated with visualization and data is provided, and editing of the channelization information can be completed through visualization operation.

Description

technical field [0001] The embodiments of the present invention relate to the field of traffic technology, and in particular to a method and device for simulation of intersection channelization. Background technique [0002] The channelization map of traffic road intersections is the necessary data for road construction, post-maintenance, adjustment, and other projects. It is also the basic material for research and analysis of road status, traffic control, traffic signal optimization and other work. However, due to various restrictions, immature technical means, or hopeless inter-departmental cooperation, the domestic public security traffic management departments at all levels and companies in the transportation field have remained at the stage of AutoCAD for the drawing of intersection channelization maps, relying solely on professional drafters The drawn drawings, on the one hand, are costly, inefficient, and complicated to modify; on the other hand, the data in the int...
