Investigation of the Pothole-Designed 3D Pedestrian Crossing to Improve Pedestrian Safety

Öz

Her yıl yaklaşık 1,19 milyon kişi trafik kazalarında hayatını kaybetmekte ve ölümlerin yarısından fazlası yayalar, motosikletliler ve bisikletliler arasında gerçekleşmektedir. Özellikle yaya kazaları, sürücülerin yayalara öncelik vermemesi ve yaya geçitlerinde yavaşlamaması nedeniyle meydana gelmektedir. Yayalar savunmasız yol kullanıcılarıdır ve hızın artması kazanın sonucunu değiştirebilir. Bu nedenle, bu çalışma yeni çukur tasarımlı 3B yaya geçidi ile görsel çekicilik sağlamayı ve sürücüleri hızlarını azaltmaya teşvik etmeyi amaçlamaktadır. Çalışma Başkent Üniversitesi Kampüsü'nde gerçekleştirilmiştir. Araç hızları, 3B yaya geçidi uygulaması öncesi ve sonrası sabah, öğlen ve akşam zirve saatlerde elde edilmiştir. Sonuç olarak, 3B yaya geçidi uygulandıktan sonra hususi araçların ortalama hızının yaklaşık %44, servis araç hızlarının %47 ve tüm araç hızlarının %46 azaldığı görülmüştür. Bağımsız t-testi, yeni 3B yaya geçidinin kurulumundan önce ve sonra ortalama hızlar arasında anlamlı bir fark olduğunu göstermiştir.

Investigation of the Pothole-Designed 3D Pedestrian Crossing to Improve Pedestrian Safety

Öz

Every year, approximately 1.19 million people lose their lives in traffic accidents, and more than half of the fatalities are among pedestrians, motorcyclists, and cyclists. Pedestrian accidents are especially attributed to drivers not prioritizing pedestrians and not slowing down at pedestrian crossings. Pedestrians are vulnerable road users and increasing speed may change the result of a crash. Therefore, this study aims to provide visual appeal and encourage drivers to reduce speed with a new pothole-designed 3D pedestrian crossing. The study was implemented on the Başkent University Campus. The vehicle speeds were obtained before and after the 3D pedestrian crossing implementation during morning, noon, and evening peak hours. In conclusion, after implementing the 3D pedestrian crossing, it was observed that the average speed of private vehicles decreased by approximately 44%, service vehicle speeds decreased by 47%, and all vehicle speeds decreased by 46%. The independent t-test showed a statistically significant difference between the before and after average speeds of installing the new 3D pedestrian crossing.
