Abstract
Otonom Araç Sistemlerinin kullanımına yönelik çalışmalar gün geçtikçe artmaktadır. Otonom araçların arazi kullanımı denemelerinin yanında yaya ve insanlı araç trafiğinin de olduğu şehir içi trafiğinde kullanımına yönelik değişik yöntem ve uygulamar devam etmektedir. Otonom aracın karma trafik içerisinde, kendine ve diğer trafik unsurlarına zarar vermeden hareket edebilmesi çözüm bekleyen en önemli problemlerin başında gelmektedir. Yapılan çalışmalarda otonom aracın güvenli seyrüseferi için mantıksal karar vericiler ve pek çok kural tabanı oluşturulmakta ve sürücü davranışı modellenmeye çalışılmaktadır. Bu çalışma kapsamında potansiyel fonksiyonlar ile modellenmiş yol ve araçlardan oluşan kavşak yapısında hareket eden otonom araçların birlerine çarpmadan şerit takibi yaparak kavşak içerisinde geçiş öncelikleri oluşturması ve hedefledikleri noktaya güvenli şekilde ulaşmaları incelenmiştir. Çalışmanın amacı mantıksal karar verme karmaşık yapısını, oluşturulan yapay potansiye alan haritası ile sağlamaktır. Yapay potansiyel alan yaklaşımı otonom araç uygulamalarında yol planlaması, şerit takibi uygulamalarında başvurulan tekniklerden birisidir. Bu çalışma ile yapay potansiyel alan yaklaşımlı yol ve şerit ile kavşak içerisinde çarpışma ihtimali olan aracın hareketli(dinamik) engel olarak modellenmesi de birleştirilerek çözüm aranmıştır. Çalışma sonucunda görülmüştür ki mantıksal karar vericilerin kullanılmasının yerine, mantıksal kural tabanına uygun olarak hazırlanmış/optimize edilmiş yapay potansiyel alan kullanılması başarılı sonuçlar vermiştir. Çalışmada yapay potansiyel alan oluşturulması için harmonik ve gaussien fonksiyonların kullanımı ile istek dışı local minimaların oluşması engellenmiştir.

Determination of Intersection Transition Priority of Autonomous Vehicles with Artificial Potential Field
Abstract
Studies on the use of Autonomous Vehicle Systems are increasing day by day. In addition to the land use trials of autonomous vehicles, various methods and practices are continuing for the use of pedestrian and manned vehicle traffic in urban traffic. The ability of the autonomous vehicle to move in mixed traffic without harming itself and other traffic elements is one of the most important problems waiting for a solution. In the studies, logical decision makers and many rule bases are created for safe navigation of autonomous vehicles and driver behavior is tried to be modeled. Within the scope of this study, autonomous vehicles moving in the intersection structure, which consists of roads and vehicles modeled with potential functions, follow the lane without hitting each other and create transition priorities in the intersection and reach their target point safely. The aim of the study is to provide the logical decision making complex with the artificial potential area map created. Artificial potential field approach is one of the techniques used in road planning and lane tracking applications in autonomous vehicle applications. In this study, a solution was sought by combining the artificial potential field approach road and lane with the vehicle that is likely to collide in the intersection as a moving (dynamic) obstacle. As a result of the study, it was seen that instead of using logical decision makers, the use of artificial potential field prepared/optimized in accordance with the logical rule base gave successful results. In the study, the formation of undesired local minimas was prevented by the use of harmonic and Gaussian functions to create an artificial potential field.
