Embodiment Construction

[0023] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0024] see figure 1 , is a structural block diagram of a road intersection steering recognition system based on vehicle data collection in an embodiment of the present invention. The road intersection steering recognition system based on vehicle data collection includes: a data service center 10 and at least one vehicle information terminal 20 communicatively connected to the data service center 10 .

[0025] The on-vehicle information terminal 20 is used to collect driving data to generate a driving data sequence and transmit the driving data sequence to the data service center. The driving data includes vehicle number, position, speed and time. Specifically, the vehicle-mounted information terminal 20 is an electronic device installed o...

Abstract

The invention discloses a method for identifying road intersection steering based on vehicle data collection. The method comprises the steps that S1, a traveling data sequence is transmitted to a data service center by a vehicle-mounted information terminal; S2, the traveling data and road intersection section information which are successfully matched are added to a road intersection section information set in a relevant mode and are stored by a data service center; S3, a history traveling track of a road intersection section is obtained according to the traveling data, a directed attribute relationship graph is generated according to the history traveling track, a GIS module is called to be matched with the directed attribute relationship graph so that steering information corresponding to the intersection section can be obtained; S4, the steering information corresponding to the intersection section can be counted and analyzed according to periods of time so that the counted result in each period of time can be obtained, and according to the counted result in a preset time span, specific steering information corresponding to the road intersection section can be identified. The invention further provides a system for identifying road intersection steering based on vehicle data collection.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a road intersection steering recognition method and system based on vehicle data collection. Background technique [0002] With the advancement of urbanization, many cities are also troubled by traffic congestion to varying degrees. In order to maximize the traffic capacity of road resources and ease the traffic pressure on urban roads, the public security traffic management department Implement measures to restrict turning by time period and vehicle type, and specific steering restriction measures, such as prohibiting left turns and prohibiting right turns by time periods and vehicle types. However, in the driving data provided by map data manufacturers, the specific turning information of road intersections is often not accurately provided, and the navigation information is prone to be inaccurate. The cycle is long, and the update cost is high, so it is impossible to real...
