Verification of the route choice model and the operational model of vessel traffic

Vessel route choice theory and modeling

Vessel route choice model by optimal control and calibration

To predict vessel traffic operations and improve safety and capacity in ports and inland waterways, a new maritime traffic model is developed. In this model, vessel behavior is categorized into a tactical level (route choice) and an operational level (the dynamics of the vessel behavior). This new maritime traffic model comprises two parts: the...

Simulation of traffic capacity of inland waterway network

The inland waterborne transportation is viewed as an economic, safe and environmentally friendly alternative to the congested road network. The traffic capacity are the critical indicator of the inland shipping performance. Actually, interacted under the complicated factors, it is challenging to conduct studies on the capacity in the networks of...

Study of Passing Ship Effects along a Bank by Delft3D-FLOW and XBeach

When a ship sails with a certain speed, there is always a return current along and under the ship. The return current induces a water level depression around the ship. When the ship travels along a bank, the flow field around the ship is asymmetrical. Additional bank effects will be induced. A reliable estimation of all these effects and the...

Actually, interacted under the complicated factors, it is challenging to conduct studies on the capacity in the networks of...

AIS data analysis for vessel behavior during strong currents and during encounters in the Botlek area in the Port of Rotterdam

Maritime traffic safety and capacity raise enormous attention nowadays, especially in ports and inland waterways with high traffic density and restricted waterway geometry. However, a limited number of factors is considered in existing maritime models. Especially influences of external factors (wind, visibility and current), vessel encounters...

Nautical traffic simulation with multi-agent system

This paper describes a microscopic nautical traffic simulation model based on multi-agent system. The ship traffic is produced from the behavior of autonomous agents that represent ships. Especially, we look at the behaviors for collision avoidance in different encountering situations with different local environmental conditions. The behavior...

AIS data anlaysis for realistic ship traffic simulations model

AIS (Automatic Identification System) data provide valuable input data for the development of simulation models to prevent shipping accidents. This paper reports on the detailed analysis of AIS data for that purpose. This analysis is focused on restricted waterways to support inland waterway simulations, comparing the differences between a...

Artificial force fields for multi-agent simulations of maritime traffic and risk estimation

A probabilistic risk model is designed to estimate probabilities of collisions for shipping accidents in busy waterways. We propose a method based on multi-agent simulation that uses an artificial force field to model ship maneuvers. The artificial force field is calibrated by AIS data (Automatic Identification System). The artificial force...

AIS data based vessel speed, course and path analysis in the Botlek area in the Port of Rotterdam

Maritime traffic safety and port capacity is increasingly important nowadays. Due to the fast development of vessel traffic in ports and waterways, a lot of attention has been paid to maritime traffic safety and port capacity. Many simulation models have been used to predict traffic safety and port capacity m ports and waterways. However,...

Quay wall design for an uncertain future

The importance of incorporating flexibility and adaptability in infrastructure is being increasingly recognized. Flexibility in infrastructure can prolong their economic lifetime by enabling them to adapt to the changed requirements. The objective of this paper is to examine if it is possible to incorporate flexibility in port infrastructure...

Calculations of the motions of a ship moored with Moormaster units

Container ships should only make very small horizontal movements at the berth for efficient (off loading of containers. This is especially a concern in ports directly facing the open ocean, where high swells at sea can cause harbour oscillations and low-frequency surge motions of the ship. Cavotec MSL has developed a new mooring unit, the...

Development of container handling in the Port of Rotterdam

During the last 60 years, the Port of Rotterdam has grown to be one of the major container ports in the world. The city of Rotterdam has changed from a fishing harbour to a Mainport in the last 600 years. The port facilities including the waterways, terminals and hinterland connections as well as the operating methods and handling techniques,...

Flexibility in Port Planning and Design

Recently, flexibility has received much attention from port researchers, designers, and managers. That is because the stability of the competitive environment of the past has been replaced by increasing uncertainty. The current economic crisis and the recent trends in ports and shipping sectors are causing port planners to rethink their approach...

Future Scenarios: Implications for Port Planning

The evolving function of a port, and the many logistical, technological and economic uncertainties under which it must operate, make the planning and design of these complex socio-technical infrastructures very challenging. A Master Plan of a port is the instrument by which the port’s (expansion) strategy in the market place is defined....
