Abstract

Proving public transportation and pedestrian priority systems is one of the most important elements of urbanization. In this context, in many developed and developing countries, especially pedestrian and bicycle safety has been prioritized and related applications have been developed and the use of environment and human-friendly transportation systems has been expanded. In this study, some traffic calming applications that can be applied in the vicinity of university campuses, schools, hospitals and health centers, where pedestrian priority and safety should be at the highest level, were evaluated. The current situation of the intersection in the analysis region determined within the scope of the study and the scenarios with different intersection types are examined and analyzed in terms of traffic indicators such as delay, service capacity, emission values and using micro scale traffic simulation program -Synchro 10. As a result of the analysis, it is revealed that the design of the roundabout with raised pedestrain crosswalks (RPC) which is one of the human-friendly traffic calming methods, both increases traffic safety in the areas where pedestrian traffic is heavy and provides flow improvement.

Erişilebilir Trafik Sakinleştirme ve Akım İyileştirme Uygulamalarının Trafiğe Olan Etkilerinin İncelenmesi

Abstract

Kentleşmenin en önemli unsurlarından biri olarak toplu taşıma ve yaya öncelikli ulaşım sisteminin sağlanması gösterilmektedir. Bu kapsamda birçok gelişmiş ve gelişmekte olan ülkede, özellikle yaya ve bisiklet güvenliği ön planda tutulmuş ve bunlarla ilgili uygulamalar geliştirilerek, çevre ve insan dostu ulaşım sistemlerinin kullanımı yaygınlaştırılmıştır. Bu çalışmada, yaya önceliği ve güvenliğinin en üst seviyede olması gereken üniversite yerleşkeleri, okullar, hastaneler ve sağlık merkezleri çevresinde yapılabilecek bazı trafik sakinleştirme uygulamaları ve bunların trafiğe olan etkileri hakkında değerlendirmeler yapılmıştır. Çalışma kapsamında belirlenen analiz bölgesindeki kavşağın mevcut durumu ve oluşturulan farklı kavşak tiplerine sahip senaryolar incelenerek gecikme, hizmet kapasitesi, emisyon değerleri gibi trafik göstergeleri açısından, Synchro 10 mikro ölçekli trafik benzetim programı kullanılarak analizler yapılmıştır. Analizler sonucunda insan dostu trafik sakinleştirme yöntemlerinden olan yükseltilmiş yaya geçitleri ile birlikte uygulanacak dönel kavşak tasarımının yaya trafiğinin yoğun olduğu bölgelerde hem trafik güvenliğini arttırdığı, hem de akım iyileşmesi sağlayabildiği görülmüştür.
