The AIS-Assisted Collision Avoidance

Abstract

Shipborne AIS provides independent traffic information to the bridge lookout on duty. This study examines the effect of AIS enhanced bridge lookout operation by means of a ship simulator. The two groups of participants, all qualified British deep sea deck officers, undertook identical simulation scenarios, but one group had the AIS on and the other did not. Significant differences were found between the two groups in reading the targets' privileged status and handling the head-on situation. Those with AIS information were found to avoid possible collisions faster than the group for whom AIS information was not available.1. AIS. 2. Radar. 3. Collision Avoidance. 4. Simulation.

The aim of a shipborne Automatic IdentificationSystem (AIS) is to help identify vessels, assist in target tracking, simplify information exchange and provide additional information to assist with situation awareness (IMO 2002). IMO Resolution A917 (22), describes AIS as a potential aid in collision avoidance and also highlights the use of AIS as an additional navigation system that supports (but does not replace) the existing navigational system. AIS provides an independent platform of traffic information that is able to enhance and support ship's radar in collision avoidance manoeuvring. Depending upon the system's specifications, near real-time Rate of Turn (ROT) and engine-speed may also be available, while voyage information and navigational status can be obtained via the AIS network.The consensus among users is that AIS has not reached system maturity in terms of the degree of system integration and data display. This study aims to examine the effect on end users operating AIS on the bridge. To examine the effect, a simulator experiment was undertaken, based on a merged AIS bridge operation with correct information displayed throughout the exercise. The focus was on the function of AIS in providing additional information to bridge operations during ship manoeuvring, with the effects of operating AIS measured by means of variable analysis.

Proposal of neural approach to maritime radar and automatic identification system tracks association

“…In the case of any problems with calibration or signal processing, the information obtained with AIS can be wrong. However, many examples have been presented showing the efficiency of AIS as an anti‐collision tool and for ship monitoring [2, 3].…”

Radar and Automatic Identification System Track Fusion in an Electronic Chart Display and Information System

“…AIS in anti-collision processes has been used by many researchers, e.g. Hsu et al (2009), Mou et al (2010), Hansen et al (2013), Silveira et al (2013) and Last et al (2014).…”

Multiobjective Optimization Based Vessel Collision Avoidance Strategy Optimization

“…With the appearance and development of new navigation equipment like AIS [5,6], advanced computer technology, and so forth, the application of intelligent optimization algorithm has been used for collision avoidance strategy searching. Genetic algorithm (GA) is a popular heuristic algorithm, which has been used for many subjects, such as system identification [7,8], supply chain [9], and scheduling problem [10].Ś mierzchalski and Michalewicz [11], Szlapczynski [12], and Szlapczynski and Szlapczynska [13] first made use of genetic algorithm to plan the route of vessel in static or dynamic environment in order to avoid obstacles.…”
