Yükseltilmiş yaya geçidinin lise çağındaki yayaların kabul edilebilir aralık seçimine etkisi

Öz

Ülkemizde taşıt trafiğine oranla yaya trafiğine daha az önem verilmektedir. Bu durumdan kaynaklanan sorunlar arttıkça, yaya davranışlarını anlamaya yönelik çalışmalara olan ilgi de artmaya başlamıştır. Bu bağlamda, makalede lise çağındaki öğrencilerin ışıksız yaya geçitlerinde kabul edilebilir aralık kabulü davranışları incelenmiştir. Çalışma bir önce sonra çalışması olarak düzenlenmiştir. İlk durumda yaya geçidi geleneksel bir ışıksız yaya geçidi iken, ikinci durumda yaya geçidi yükseltilmiş yaya geçidine dönüştürülmüştür. Bu makalede yükseltilmiş yaya geçidinin lise çağındaki öğrencilerin kabul edilebilir aralık davranışına etkilerinin bulunması amaçlanmıştır. Çalışmada İzmir ilinde bir lise yakınında bulunan ışıksız yaya geçidi seçilmiştir. Veriler sabah saat 7.00-8.00 sa. arasında toplanmıştır. Ofis ortamında video görüntülerinden ayıklanan veriler iki yönlü ve tek yönlü varyans analizi (ANOVA) yöntemi kullanılarak çözümlenmiştir. Öğrencilerin kurallara uygun olarak geçişi yaya geçidi yükseltilmiş yaya geçidine dönüştürüldükten sonra artmıştır. Ayrıca ortalama taşıt hızları ve %85’lik taşıt hızları hem yaya geçidi yükseltilmeden önce hem de yükseltildikten sonra hesaplanmıştır.

Anahtar Kelimeler

Effect of raised midblock crossing on the high school pedestrians’ choice of acceptable gap behavior

Abstract

Pedestrian traffic has less priority than vehicle traffic in Turkey’s transportation system. In recent years, there has been a growing interest in understanding pedestrians’ behavior. This paper investigates high school students’ (15-18 age range) gap acceptance behavior at unsignalized midblock crossings by designing a before and after study. The midblock crossing is conventional in the first situation. But after, the midblock crossing is raised. This paper aims to find the effect of raised midblock crossing on pedestrians’ acceptable gap behavior. In this study, a midblock crossing near a high school in Izmir City was chosen. Data was gathered by using two video cameras in the morning (7.00-8.00 AM). The obtained data were extracted from the footage. The data were analyzed by performing two-way and one-way analysis of variance (ANOVA). The legal crossing rate of the students increased with the installation of the raised midblock crossing. Also, average vehicle speed and 85th percentile speed determined for both situations. Thus, the number of acceptable gaps increased as well as the waiting time decreased significantly.
