چکیده
AIS (Automatic Identification System) data provides valuable input parameters in ship traffic simulation models for risk analysis and the prevention of shipping accidents. This paper reports on the detailed analysis of AIS data for modeling purposes. This analysis is focused on restricted waterways to support inland waterway simulations, comparing the differences between a narrow waterway in the Netherlands (narrow waterway in the Port of Rotterdam) and a wide one in China (wide waterway of Yangtze River close to the Su-Tong Bridge). It is shown that straightforward statistical distributions can be used to characterize position, speed, heading and interval times for different types and sizes of ships. However, the distributions for different characteristics of ship behaviors for narrow and wide waterways differ significantly.

متن کاملVisualizing Anomalies and Traffic Rules in a Maritime Setting Using Potential Fields
Automatic Identification System (AIS) transponders are used to identify and locate traffic. By recording AIS data, in a marine setting, it is possible to observe precise ship movements. An AIS-based maritime data modeling method is developed using a potential fields based method for extracting traffic patterns and detecting anomalies. The three aspects of potential field theory: charge accumula...
متن کاملCharacteristics of Ship Movements in a Fairway
Abstract In a coastal area, all of the vessels are always exposed to the potential risk, taking into the maritime accident statistics account over the last decades. To manage vessels underway safety, the characteristics of ship movements in a fairway should be recognized by VTS system or VTS operators. The IMO has already mandated the shipboard carriage of AIS since 2004, as stated in SOLAS Cha...
متن کاملA vessel noise budget for Admiralty Inlet, Puget Sound, Washington (USA).
One calendar year of Automatic Identification System (AIS) ship-traffic data was paired with hydrophone recordings to assess ambient noise in northern Admiralty Inlet, Puget Sound, WA (USA) and to quantify the contribution of vessel traffic. The study region included inland waters of the Salish Sea within a 20 km radius of the hydrophone deployment site. Spectra and hourly, daily, and monthly a...
متن کاملEvaluation of AIS Reception in Arctic Regions From Space by using a Stratospheric Balloon Flight
Due to the increased melting season in the arctic regions, especially in the seas surrounding Greenland, there has been an increased interest in utilizing these water ways, both as a efficient transport route and an attractive leisure destination. However, with heavier traffic comes an increased risk of accidents. Due to the immense size and poor infrastructure of Greenland, it is not feasible ...
