Water-borne traffic conflict data automatic acquisition method for ship routing scheme warning region

Abstract

The invention discloses a water-borne traffic conflict data automatic acquisition method for a ship routing scheme warning region. The water-borne traffic conflict data automatic acquisition method is characterized by comprising the steps of: analyzing ship collision risk degree influencing factors, determining water-borne traffic conflict parameters according to a ship automatic identification system AIS, acquiring water-borne traffic conflict data samples of the ship routing scheme warning region, and establishing an SVM classification model; and embedding a libsvm software package into an electronic chart display and information system ECDIS program in a VC++ 6.0 environment, importing the SVM classification model, and judging and recording ship collision risk degree data in the region pairwise in real time. The water-borne traffic conflict data automatic acquisition method has the advantages of realizing judgment of water-borne traffic conflict and severity degree thereof, recording the parameters when the conflict occurs, and making statistics of traffic flow, flow direction and the like in the whole warning region.

Description

technical field [0001] The invention relates to the technical field of water traffic safety, in particular to a method for automatically collecting data on water traffic conflicts in a warning area of ​​a ship routing system. Background technique [0002] Ship routing system, as a "highway on the sea", represents the development direction of water ship navigation order management. Most of the important international navigation waters in the world have established ship routing system. Practice has proved that the ship routing system has played a positive role in regulating ship navigation, effectively separating opposite ship traffic flows, reducing the encounter rate of ships, etc., and has fundamentally improved the safety situation and navigation order in the water area of ​​the ship routing system. , and achieved good security benefits and economic and social benefits. [0003] In the field of ship routing system, although the implementation of the traffic separation sys...

Problems solved by technology

Road traffic conflict data collection methods mainly include manual survey, video survey and digital image processing technology. The first two methods are labor-intensive and the reliability of observers is difficult to guarantee. The third method has not yet matured at this stage, and the constraints of data collection To a certain extent, it hinders the development and application of road traffic conflict technology

In addition, in the field of water transportation, most of the existing research on the risk of ship collision only analyzes the calculation method of the risk of ship collision between two ships, without further automatic calculation and statistics of the risk of ship collision in local waters. Engineering practice Applicability is not strong
