Karayolu trafik kazalarına yeni bir yaklaşım: Kaza analiz kesimleri modeli

Öz

Bu çalışmada kaza analizleri konusunda yapılan araştırmaların geniş bir literatür taraması yapılarak kaza analiz kesimleri adında yeni bir yaklaşım modeli geliştirilmiştir. Bu yaklaşımda, kaza analizi yapılacak olan yolun geometrik ve trafik özellikleri dikkate alınarak yol kesimi homojen özellikte kaza analiz kesimlerine bölünmüştür. Çalışma bölgesinde meydana gelen trafik kazalarına etki eden faktörler ve bu faktörlerin sebep olduğu kaza şiddetleri belirlenmiştir. Her bir analiz kesimine ait geçmiş trafik kazaları belirli bir zaman periyodu için incelenmiş, kaza şiddetlerine ve kazaya etki eden faktörlere ağırlık değerleri verilmiştir. Gerçekleştirilen analizlerle her bir kaza analiz kesimi, kaza açısından önem derecesine göre sıralanmıştır. Sonuç olarak, geliştirilen model verileri teorik olarak üretilen kuramsal bir yol kesiminde test edilmiş, diğer kaza analiz modelleriyle karşılaştırılmış ve güvenilir sonuçlar elde edilmiştir.

A new approach for road traffic accidents: Crash analysis segments model

Abstract

In this study a comprehensive literature review was done on road traffic accident studies and a new approach named crash analysis segments was developed. In this approach, the case area was divided into homogenous analyses segments by considering geometrical and traffic properties of the road segment. The traffic accidents and the accidents factors with their crash severities were defined. The weighted ratios were assigned to the crash factors and to the crash severities after historical traffic accident records were gathered during a defined period for each analysis segments. Each crash analyses segments were ranked by considering their prioritisation after some analyses. Consequently, the developed model was tested for a hypothetical road segment with a data set generated theoretically and compared with the other crash analysis models and reliable results were found.
