Mikrosimülasyon Kullanılarak Bir Kavşağın Trafik Yönetim Ölçümlerinin Değerlendirilmesi

Trafik yönetiminde ele alınan iki ana amaç sinyalize olmayan kavşaklardaki trafik güvenliği ve yolculuk verimliliğidir. Mikroskopik simülasyonlar ulaşım projelerinde ve yönetiminde yaygın bir şekilde kullanılmaktadırlar çünkü simülasyon güvenlidir daha ekonomiktir ve arazi uygulama ve denemelerinden daha hızlıdır. Bu çalışmada Atatürk Üniversitesi Kampüsündeki en yoğun trafik hacmine sahip ve yıllık ortalama 15 kazanın olduğu Teknokent Kavşağı incelenmiştir. Araziden elde edilen ölçümler VISSIM programı ile simüle edilmiştir. Farklı sinyal programları ve geometrik düzenlemeler önerilmiş ve uygulanmıştır. Uygulamalardan sonra ilgili kavşakta 1,5 yıldır herhangi bir kaza olmamıştır. Önerilen ve uygulanan sağa dönüş adaları kollardaki gecikmeleri minimize etmiştir

Evolution of a Junction Traffic Management Measures Using

Travel efficiency and traffic safety of unsignalized intersections are two main objectives considered in traffic management. Microscopic simulations are widely used in transportation operations and management analysis because "simulation is safer, less expensive and faster than field implementation and testing". VISSIM is a microscopic traffic simulation program. The heaviest traffic volume and annually average 15 accidents occurred in Atatürk University campus that connect Çat Road to Hospital named as Teknokent Junction was studied. Field observations were simulated in VISSIM. Signalization program and geometric changes were proposed and applied in the field. After the application, no traffic accident was observed in the junction for 1,5 years. Applied right turn island minimized the delay time for the arms
