Embodiment Construction

[0068] Below Figure 1 ~ 10 The preferred embodiment of the present invention will be specifically described.

[0069] The basic map of maritime traffic flow is closely related to indicators such as ability, congestion coefficient. It not only helps to solve the pain of the Gangshi sector through the ability of the channel through ability, but also the key parameters of smart ship independent navigation. Therefore, by selecting a large number of AIS historical data, through a certain algorithm, the basic map of the sea traffic is drawn, in order to clarify the characteristics of maritime traffic flow, it is also an urgent need to solve the problem of maritime transportation. .

[0070] In the embodiment of the present invention, there is provided a method of drawing a sea traffic flow based on AIS data, including the following steps:

[0071] 1. Select the research channel and establish a channel coordinate system. First, you need to determine the latitude range of the channel and ...

Abstract

The invention discloses a marine traffic flow basic diagram drawing method based on AIS data. The method comprises the following steps of: selecting a research channel and establishing a channel coordinate system; acquiring and cleaning AIS data; converting longitude and latitude coordinates of ships; determining the average ship length and the average ship width of the ships in the channel, and calculating horizontal coordinate values of the ships entering the channel; performing channel subdivision; drawing a space-time trajectory diagram of the ships in the channel; calculating maritime traffic flow characteristic parameters; determining key characteristic parameters of marine traffic flow; and drawing a maritime traffic flow basic diagram. According to the method, construction of the maritime traffic flow basic diagram based on the large amount of AIS data is achieved, a new way is provided for port and navigation departments or related researchers to analyze and manage maritime traffic, and specific practical application of the method is carried out in maritime traffic flow research.

Description

Technical field [0001] The present invention relates to a marine traffic flow base drawing method based on AIS data. Background technique [0002] The situation in maritime traffic is more complex, which makes a higher requirements for the analysis and development capacity of traffic trends within the waterway. The research of ship traffic flow originates from road traffic flow theory, and the research methods and means between the two have a certain interoperability, drawing on road traffic flow theory to study maritime traffic characteristic parameters has solid theoretical basis. According to the AIS (Automatic Identification System Automatic Identity System) data, the researchers have facilitated historical data of ship sailing in a certain waters (including the short-space distribution of the ship), and the water traffic AIS data resources for their spatial detectors are It is convenient to offer at sea traffic research. [0003] At present, due to the essential difference b...
