摘要

本文旨在根据高速公路新建项目的技术特征和几何特征，对事故高危区域进行前瞻性预测。本研究的目的是为道路项目经理提供更好的车辆乘员类别道路安全评估工具。所使用的方法结合了国际道路评估计划(IRAP)方法和地理信息系统(GIS)。IRAP程序除了使用星级评级进行分类外，还可以对每100米路段进行风险计算和分类;而GIS则用于绘制风险图并识别高风险事故段。该方法应用于位于阿尔及利亚GHAZAOUET的一个110公里的新公路项目。研究结果表明，这种组合方法在多个方面都具有创新性，因为它是道路安全专家有效的决策辅助工具。因此，在进行现场道路安全检查之前，它可以以更快的方式瞄准易发生事故的路段。从技术上讲，本研究表明，在车速超过80 km/h时，存在紧密弯曲的半径混合以及道路出口的存在是影响车辆乘员安全的主要因素。速度控制;因此，它仍然是提高安全的最便宜的措施之一。

Application of the IRAP Method Combined with GIS to Improve Road Safety on New Highway Projects in Algeria

This article aims to proactively predict high-risk accident areas in a new highway project in terms of its technical and geometric characteristics. The purpose of this study is to provide road project managers with better road safety assessment tools for the vehicle occupant category. The methodology used combines the International Road Assessment Program (IRAP) methodology and the Geographic Information System (GIS). The IRAP program enables the calculation and classification of risks for each 100-meter segment besides their categorization using a star rating; whereas, the GIS is used to map the risks and identify high-risk accident segments. This method was applied to a new highway project of 110 hectometres located in GHAZAOUET in Algeria. The results of the study revealed that this combined method is innovative in more than one way as it is an effective decision-making aid tool for road safety experts. It, therefore, makes it possible to target accident-prone sections in a faster way before carrying out on site road safety inspections. Technically speaking, this study shows that the existence of closely curved radii mixed at traffic speeds exceeding 80 km/h and the presence of road exits are the main factors affecting the safety of vehicle occupants. Speed control; thus, remains one among the cheapest measures to improve safety.
