Intersections have significant effect in highway networks and are categorized according to their various characteristics. Roundabouts, one of the types of at-grade intersections, have been using since the beginning of the twentieth century. Modern roundabouts are common in recent years, especially in urban intersections, thanks to the give way rule to circulating vehicles around the island and its geometry that provides high safety by ensuring low and constant speed movement of the vehicles joining from the approaches. However, this type of intersection is sensitive to unbalanced flow patterns in the approaches, it cannot provide the necessary gap to the vehicles that want to join the intersection under these conditions hence delays and queues occur in the intersection legs. In order to reduce emerged excessive delay and queuing problems, roundabout metering has started to be used as a solution option. In this article, the effect of roundabout metering on intersection performance is examined in the light of the available literature. In this study, delay was used as the primary parameter to evaluate the performance of roundabouts, also environmental and economic impacts were mentioned. In the investigated studies, it was seen that roundabout metering shows successful results under several flow patterns. Thus, it was mentioned that roundabout metering should be considered as an option by taking factors into account such as the geometry of the roundabouts in Turkey and local driver behaviors.

Dönel kavşaklarda meydana gelen dengesiz akımlara bir çözüm önerisi olarak kısmi denetimli sinyalize dönel kavşaklar: Bir literatür araştırması

Öz

Karayolu ağlarında büyük öneme sahip olan kavşaklar, çeşitli özelliklerine göre kategorilere ayrılır. Hemzemin kavşak tiplerinden biri olan dönel kavşaklar yirminci yüzyılın başından itibaren kullanılmaktadır. Modern dönel kavşaklar, ada etrafında dönen araca yol ver kuralı ve yüksek güvenliğe sahip geometrisi ile yaklaşım kollarından katılan araçların düşük ve sabit hızla hareketini sağlar. Bu nedenle modern dönel kavşaklar, son yıllarda özellikle kentsel kavşaklarda tercih edilmektedir. Ancak bu kavşak tipi, yaklaşım kollarındaki dengesiz akımlara karşı hassas olduğundan, bu şartlar altında kavşağa katılmak isteyen araçlar arasında gerekli olan boşluğu sağlayamaz ve kavşak kollarında gecikmeler ve kuyruklanmalar oluşur. Meydana gelen aşırı gecikme ve kuyruklanma sorunlarının azaltılması amacıyla kısmi denetimli sinyalize dönel kavşaklar bir çözüm seçeneği olarak kullanılmaya başlanmıştır. Bu makalede, kısmi denetimli sinyalize dönel kavşakların kavşak performansı üzerindeki etkisi mevcut literatür ışığında incelenmiştir. Bu çalışmada dönel kavşakların performanslarını değerlendirmek için temel parametre olarak gecikme kullanılmış, ayrıca çevresel ve ekonomik etkilere de değinilmiştir. İncelenen çalışmalarda, kısmi denetimli sinyalize dönel kavşakların çeşitli akım talepleri altında başarılı sonuçlar verdiği görülmüştür.Bu sebeple kısmi denetimli sinyalize dönel kavşakların ülkemizde bulunan dönel kavşakların geometrileri ve yerel sürücü davranışları gibi değişkenler de göz önünde bulundurulması kaydıyla bir seçenek olarak değerlendirilmesi gerektiğinden bahsedilmiştir.
