Traffic information processing method and traffic information processing device based on intersections and sections

Abstract

The invention provides a road network representation method, a road network representation device, a traffic information data processing method and a traffic information data processing system adopting the representation method. The traffic information data processing method comprises: a conversion step of converting traffic information data into the traffic information data of intersections and sections respectively according to a correspondence relationship between a road network of one or more road maps and the road network represented by the intersections and the sections, wherein the road network represented by the intersections and the sections is obtained by the road network representation method; and a fusion step of fusing the converted traffic information data of the intersections and the sections to obtain the uniform traffic information data. In the methods, the device and the system provided by the invention, the road network represented by the sections and the intersections serves as an intermediate model, the importance of the intersections serving as hub nodes of the road network is emphasized, cartographic representation of different forms is compatible so as to provide generality, and more correct and fuller traffic information can be acquired by fusing the traffic information data of different data sources, thereby being favourable for service such as traffic information prediction.

Description

technical field [0001] The invention relates to the field of traffic information data processing, in particular to the representation of a road network based on intersections and road sections, and the processing of traffic information data from different data sources by using the representation. Background technique [0002] In modern society, with the rapid development of social economy and the increasing popularity of automobiles, the pressure on urban traffic is increasing, and traffic congestion is becoming more and more serious. Reducing traffic congestion is beneficial to saving travel time for drivers, reducing fuel consumption, improving urban economic efficiency and promoting environmental protection. Therefore, the traffic information service system is one of the important components of the urban intelligent traffic system. [0003] In terms of traffic information collection, the current rapid development of multimedia technology, mobile communication technology ...

Problems solved by technology

Although this method tries to describe traffic information in a language that is more in line with people's daily behavior, it is basically limited to the text level, and cannot map this model to different geographic networks, and cannot perform multi-source data fusion

[0011] In summary, the existing traffic information modeling or expression methods still have deficiencies, and a model for traffic information modeling has not been established from a general and practical perspective.
