Abstract

Road safety index is an important indicator that has been recently introduced as a useful tool to measure the quality of life in many countries and cities. Road safety index is a complex index and it has at least three main components, including road user behavior, vehicle safety, and road infrastructure effects. Many researchers have selected studying road performance from road safety index perspective due to its feasibility and applicability. To calculate the road safety index, a novel approach was proposed using data envelopment analysis method. In this paper, the selected road safety indicators are classified into two groups, namely the desirable and undesirable indicators. The new approach was applied for a case study in the roads of East Azerbaijan Province in Iran. Inefficient roads were recognized applying the proposed method, and strategies were suggested to improve the efficiency of these roads.

Abstract [Persian]

شاخص ایمنی جاده یک شاخص مهمی است که اخیرا به عنوان یک ابزار مفید برای اندازه گیری کیفیت زندگی در بسیاری از کشورها و شهرها برحسب امنیت جاده معرفی شده است. شاخص ایمنی جاده یک شاخص پیچیده ای است و حداقل دارای سه جزء اصلی، رفتار کاربر جاده، ایمنی وسایل نقلیه و اثرات زیرساخت های جاده ای است. بسیاری از محققان به دلیل امکان سنجی و کاربرد آن، مطالعه از نظر جاده را از دیدگاه شاخص ایمنی جاده انتخاب کرده اند.بسیاری از محققان مطالعه عملکرد جاده را از دیدگاه شاخص ایمنی جاده بخاطر امکان سنجی و کاربرد آن، انتخاب کرده اند. با استفاده از روش تحلیل پوششی داده‌ها، رویکرد جدیدی برای محاسبه شاخص ایمنی جاده‌ها پیشنهاد می‌شود. در این مقاله، شاخص‌های ایمنی جاده انتخاب شده، در دو گروه شاخص‌های مطلوب و نامطلوب دسته‌بندی می‌شوند. رویکرد جدید برای مطالعه موردی جاده‌های استان آذربایجان شرقی ایران بکار گرفته می‌شود. با استفاده از روش پیشنهادی، جاده‌های ناکارآ شناسایی می‌شوند و استراتژی‌هایی برای بهبود کارایی این جاده‌ها پیشنهاد می‌شوند.
