Road merging method and road merging device

Abstract

The invention discloses a road merging method and a road merging device, which are used for preprocessing a real-time traffic rendered road. The method comprises the following steps: reading a road message; searching for crossing linkage information which contains the road message from a preset crossing linkage information set; acquiring a to-be-merged road of the road corresponding to the road message according to the crossing linkage information; and merging the road and the to-be-merged road into a whole road. The invention also discloses a road merging device for realizing the method. By using the road merging method and the road merging device provided by the invention, the smooth connection of shifted roads can be ensured.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a road merging method and a road merging device. Background technique [0002] With the development of the economy, the traffic capacity of the road network is difficult to meet the growing traffic demand. Traffic accidents, traffic congestion, environmental pollution and energy shortage have become problems that plague the transportation field. In this context, how to consider people, vehicles, roads and the environment from a systematic point of view, reduce economic losses, improve traffic operation efficiency and safety, and use various high-tech ideas to solve traffic problems came into being. At the same time, advanced technologies such as communication, control and information technology provide strong technical support for the realization of the above ideas, all of which make Intelligent Transport Systems (Intelligent Transport Systems, ITS) come into b...

Problems solved by technology

Since the existing road offset algorithm obtains the starting point and end point of the offset road by vertically offsetting the starting point and end point of each road, the two roads connected smoothly before the offset (such as figure 1 Offset roads (such as the roads AB and CD) shown figure 1 There is a gap between the shown roads A'B' and C'D'), so that the real-time traffic status cannot be displayed between the offset roads A'B' and C'D', so that the real-time traffic status finally presented to the pedestrian The status does not match the actual situation, causing travelers to misunderstand

[0006] In order to solve the problem of gaps in offset roads, it is urgent to provide a road processing technology. The existing road offset algorithm is used to offset the roads obtained through this processing technology, and the smooth connection of the offset roads can be realized.
