ABSTRACT
This paper presents cellular approach to analysis of influence of maritime traffic organization on the collision risk. Cellular automata are often applied to road traffic simulation and are very useful in emulating priority rules of the road are supposed to work in traffic (Maerivoet & De Moor 2005, Wolfram 1986), especially in a roundabout (Chen et al. 2006). However, this approach has not been used for describing vessels motion. The problem of traffic simulation in an intersection can be solved by multi-agent system approach (Doniec et al. 2008). Specifically, a multi-agent model using priority relations allows for simulating traffic at road junction for different priority scenarios. Then, agents approaching an intersection coordinate their actions in order to avoid collision. Similar approach is presented in this paper to describe vessel dynamic and behavior at waterways’ crossing including various priority scenarios at restricted area. Detailed analysis of simulation results for different traffic schemes can be effectively used in
1 INTRODUCTION
Permanent development of transportation systems and its infrastructure has influence on increasing demand on Vessel Traffic Management and Information Systems to improve safety and effectiveness of maritime transportation. Intelligent Transport Systems (ITS), using a range of information and communication technologies, can face problems associated with maritime traffic management and safety improvement (Perera et al. 2012, Pietrzykowski 2011). One of maritime safety tasks is to reduce the risk of collisions at waterways’ crossings. In this paper there is presented simulation approach to this topic with application of cellular automaton model.
