Traffic information acquisition device and method

Abstract

The embodiment of the invention discloses a traffic information acquisition device and method, which are used for realizing fine traffic information acqusition to acquire accurate traffic information so as to improve the effectiveness of a traffic regulation strategy. The device of the embodiment of the invention comprises a first traffic information detector and a second traffic information detector, wherein the first traffic information detector is arranged at a traffic solid line region for acquiring traffic information of the solid line region; the traffic solid line region is a vehicle waiting region with a traffic solid line as a lane line and a traffic stop line as a zone boundary; the second traffic information detector is arranged at a traffic virtual line region for acquiring traffic information of the virtual line region; the traffic virtual line region is a vehicle running region with the traffic virtual line as a lane line. The embodiment of the invention also provides the traffic information acqusition method, which is used for realizing fine traffic information acqusition to acquire accurate traffic information so as to improve the effectiveness of the traffic regulation strategy.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of traffic information, and in particular, to a device and method for collecting traffic information. Background technique [0002] The basic traffic information is the traffic information directly collected by various means, and it is the original input data of the traffic management system. These data can be further processed according to different needs, so as to obtain more valuable information that meets different needs. The basic traffic information can be divided into two categories: static traffic information and dynamic traffic information according to the frequency of its change. [0003] Static traffic information mainly includes urban road network basic information (such as road length), urban basic geographic information (such as road network distribution), vehicle ownership information, and traffic management information. [0004] Dynamic traffic information mainly refer...

Problems solved by technology

[0006] However, since the traffic information detector is only deployed in the intersection area, it cannot directly and effectively monitor the traffic status of other areas on the road section, and the traffic control system can only obtain local information of the intersection area, that is to say, the existing The traffic information collected by the technology has a large error with the actual traffic conditions, making it impossible to accurately output the global optimal control strategy
