Embodiment Construction
[0042] method embodiment
[0043] refer to figure 1 , the present embodiment provides a method for analyzing traffic volume in adjacent areas based on high-definition checkpoint data, comprising the following steps:
[0044] S1. Obtain the checkpoint data collected by all checkpoints in the road network within a preset time period to form a data set;
[0045] The bayonet referred to in this application refers to the road high-definition bayonet, which is referred to as the bayonet for short in this application; the preset time period here is a time period set in advance, which can be one day or one week, according to the analysis requirements Make settings.
[0046] S2. According to the acquired data set, extract and obtain the bayonet sequence of all vehicles passing by in chronological order; for example, in the data set, the bayonet numbers of all bayonets passing by in chronological order in the bayonet data corresponding to a vehicle are arranged in sequence as B-H-J-K...

The invention discloses a method and system for analyzing traffic volume in adjacent areas based on high-definition checkpoint data. The method includes: acquiring checkpoint data collected within a preset time period of all checkpoints in a road network to form a data set; extracting Obtain the bayonet sequence of all vehicles passing by in chronological order; after mapping the traffic area number corresponding to the bayonet number in the bayonet sequence of each vehicle, obtain the original area sequence of each vehicle; the original area sequence of each vehicle Perform cleaning to obtain the corresponding pretreatment area sequence; correct the pretreatment area sequence of each vehicle to obtain the corresponding correction area sequence; count the traffic volume of all adjacent areas in the road network. The present invention can obtain the traffic volume of all adjacent areas in the road network by statistics, thereby reflecting the motor vehicle interaction volume in the adjacent areas connecting roads between adjacent traffic areas, can intuitively reflect the traffic conditions in adjacent areas, and can be widely used in intelligent in the transportation industry.
Description
technical field [0001] The invention relates to the field of intelligent monitoring of road traffic conditions, in particular to a method and system for analyzing traffic volume in adjacent areas based on high-definition checkpoint data. Background technique [0002] In the road network of a city, the traffic operation status of a certain area can generally be analyzed and judged by indicators such as traffic flow, saturation, service level, travel time, and delay. Indicators such as traffic flow, saturation, and service level are generally used in traffic planning, design, and traffic impact assessment. They are relatively abstract and mainly reflect the demand, capacity, and carrying capacity of the macroscopic road network where the area is located. For users—passengers and drivers, it is impossible to intuitively and visually know the traffic conditions in the area. In general, the current assessment methods for traffic conditions in various regions of the road network ...
