Genetic algorithm for shipping route estimation with long-range tracking data : automatic reconstruction of shipping routes based on the historical ship positions for maritime safety applications

Ship tracking systems allow Maritime Organizations that are concerned with the Safety at Sea to obtain information on the current location and route of merchant vessels. Thanks to Space technology in recent years the geographical coverage of the ship tracking platforms has increased significantly, from radar based near-shore traffic monitoring towards a worldwide picture of the maritime traffic situation. The long-range tracking systems currently in operations allow the storage of ship position data over many years: a valuable source of knowledge about the shipping routes between different ocean regions. The outcome of this Master project is a software prototype for the estimation of the most operated shipping route between any two geographical locations. The analysis is based on the historical ship positions acquired with long-range tracking systems. The proposed approach makes use of a Genetic Algorithm applied on a training set of relevant ship positions extracted from the long-term storage tracking database of the European Maritime Safety Agency (EMSA). The analysis of some representative shipping routes is presented and the quality of the results and their operational applications are assessed by a Maritime Safety expert.

A segurança no terrorismo e na indústria dos eventos

Nowadays, safety and security regarding the tourism and events industries are a fundamental subject to society. Portugal’s tourism has significantly increased its number of visitors, whether due to the increasing number of cruisers docking in Lisbon, or due to visitors arriving by air, travelling the country from North to South and staying in the most varied accommodation units. Issues like human security and internal security of the different countries, even the security in the world, as development factors of a modern society, are discussed on a daily basis. On the contrary, few deal with tourism and major events security as being part of internal security, as well as the existing barriers tourism encounters to integrate the system for fighting terrorism. Although two distinct activities, they are complementary and may influence the country’s economy, provided that they can offer certainty to all actors involved. It is this substance that organised crime groups look for when planning terror acts. Therefore, as tourism can offer deception and shelter opportunities and events the theatre of a possible attack, those events assemble all the necessary conditions for an attack to achieve its goals.
