Problems solved by technology

[0003] In the prior art, the dynamic traffic information (for example, road congestion) is usually determined by collecting the traffic flow on the road. This method of determining the dynamic traffic information only based on the single factor of the traffic flow cannot comprehensively consider the traffic flow of each unit. characteristics (for example, the driving speed of each vehicle, etc.), so that dynamic traffic information cannot be accurately reflected
[0004] In addition, in the prior art, many situations need to be manually confirmed, which undoubtedly affects the real-time and current situation of dynamic traffic information

Abstract

The present invention discloses a method and device for determining dynamic traffic information based on user trajectory, wherein the method includes: collecting the vehicle trajectory of the user; matching the collected vehicle trajectory with the vehicle road network, and determining each According to the matching relationship between the vehicle trajectory and each road in the vehicle network, the road condition of the first road is determined according to the trajectory information of the vehicle trajectory matched with the first road, wherein the first road is the A road in a vehicular road network. By adopting the present invention, dynamic traffic information can be determined automatically and in real time according to the matching relationship between the user's vehicle trajectory and the road, fully reflecting the current situation of the road conditions.

Description

technical field [0001] The present invention relates to the fields of global positioning system, dynamic traffic information, etc., and more specifically, relates to a method and device for determining dynamic traffic information based on user trajectory. Background technique [0002] Users usually pay more attention to traffic conditions when traveling, and how to provide users with accurate, effective, and real-time traffic information is a problem that the industry focuses on. [0003] In the prior art, the dynamic traffic information (for example, road congestion) is usually determined by collecting the traffic flow on the road. This method of determining the dynamic traffic information only based on the single factor of the traffic flow cannot comprehensively consider the traffic flow of each unit. characteristics (for example, the driving speed of each vehicle, etc.), so that dynamic traffic information cannot be accurately reflected. [0004] In addition, in the prio...
