Short road chain real-time traffic information merging method, device and system

Abstract

The embodiment of the invention discloses a short road chain real-time traffic information merging method, a device and a system, which relate to the field of urban road traffic condition information processing and application, and improve the short road chain real-time traffic information accuracy. The method comprises the following steps: merging short road chain real-time traffic information which meets the merging conditions and adjacent real-time traffic information into merged real-time traffic information, the short road chain real-time traffic information is less than or equal to real-time traffic information with the length being a set value, and the merged real-time traffic information contains the corresponding relationship between the short road chain real-time traffic information and the real-time traffic information merged with the same and road chains that the short road chain real-time traffic information and the real-time traffic information contain; and organizing, compiling and saving the merged real-time traffic information to map data. The invention is applied to short road chain RTIC processing.

Description

technical field [0001] The invention relates to the field of processing and application of urban road traffic condition information, in particular to a method, device and system for merging and processing real-time traffic information of short and small road links. Background technique [0002] In the process of processing urban traffic information, since there are many short links in the road network (the smallest unit of the road in the map data, referred to as the link), if the dynamic traffic information is displayed in the unit of Link, the state representation will appear relatively fragmented , the amount of data is relatively large, and it is not conducive to traffic travel. [0003] RTIC (Real-Time Information of China, real-time traffic information in China) is a kind of location reference information, which can be used to display dynamic traffic information by establishing the RTIC location reference. An RTIC can contain one or more Links, which is based on an ab...

Problems solved by technology

[0006] When the inventor realizes the technical solution of the present invention, he finds that the prior art has at least the following problems: the processing method of the short road link RTIC is the same as that of the long RTIC, and the information of the two GPS points is used to perform road status and travel time for the RTIC contained in it. Processing, did not consider the problem that the short road link RTIC is very sensitive to the running state of the vehicle (such as the acceleration and deceleration process of the vehicle), resulting in the generated travel time and congestion state not in line with the actual situation, and the effect is not ideal
