A Study on Local Traffic Management to Improve Marine Traffic Safety in the Istanbul Strait

Abstract

The Istanbul Strait is one of the most congested waterways in the world and is difficult to navigate due to its ‘S-shaped’ geographic structure (Akten, 2004). Much of the local marine traffic affects navigation safety. Results of Yurtoren and Inoue (2004)'s study, which investigated navigational risks in the Istanbul Strait in terms of manoeuvring difficulties and accident statistics, indicates the necessity of effective and applicable local traffic management in the southern entrance of the Strait. In this study, Marine Traffic Fast Time Simulation (MTFTS) studies are used and an attempt is made to improve navigation safety by proposing Local Traffic Separation Schemes (LTSS).

A quantitative approach for delineating principal fairways of ship passages through a strait

“…season, direction) are also helpful to view the effect of seasonal and directional factors for maritime corridors. There is no information about the temporal dimension of strait corridors and space-use patterns for traditional TSS analysis (Aydogdu et al, 2012;Johnson, 1973;Szlapczynski, 2013). While our proposed method is useful not only for mapping the total area (i.e.…”

“…To minimise the possibility of collisions in ships passage straits, states bordering certain congested straits may create routing systems to separate vessels, control crossing and meeting situations. Developing ship routing schemes in congested straits have become an important topic in maritime transport, especially the straits heavily used for international navigation, such as the Dover Strait (Johnson, 1973;Squire, Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/oceaneng 2003) the Istanbul Strait (Aydogdu et al, 2012), and the Malacca Strait (Qu et al, 2011;Zaman et al, 2014). However, only 15 straits throughout the world have implemented Traffic Separation Schemes (TSS) approved by the IMO (UKHO, 2012).…”

“…Thus they are empirically significant in recommended routes for sailors. In previous work involved ship routing system on straits (Aydogdu et al, 2012), PFs (so-called main traffic flows) are subjectively selected based on mariners' experience, which is not quantitatively repeatable.…”

“…For example, Kaluza et al (2010) extracted 490,517 routes linking 36,351 distinct pairs of OriginDestination in annual global AIS database to represent the global shipping network. Eight main Origin-Destinations were defined as main routes in the Istanbul Strait (Aydogdu et al, 2012). However the method of Origin-Destination matrices only concerns the origin and destination of each movement but ignores the actual trajectories.…”

A temporal analysis of vessel type traffic in Istanbul Strait anchorages

“…On the other hand, the Istanbul Strait, one of the busiest waterways in the world and the only sea route between the Mediterranean, Aegean, and the Black Sea, is a logistic node in the region that necessitates constant attention [1]. In this regard, previous studies concentrated on the improvement of marine traffic management in the Istanbul Strait via a number of methodologies including the following: proposing a mathematical formulation for maritime scheduling [2], suggesting a particular navigation safety support model [3], offering local traffic separation schemes [4], performance evaluation of the service of an online precise point positioning (PPP) system with the aim of positioning in Halic Bay [5], and applying the method of generic fuzzy analytic hierarchy for evaluating maritime risks [6]. On the other hand, a maritime accident analysis in the Southern Anchorage Area can be found in [7].…”
