Abstract

Traffic safety is among the most serious topics of transportation engineering studies. Different methods have been proposed for safety evaluations. Applying surrogate safety measures (SSM) to predict the crash likelihood and severity is a relatively new approach, which needs microscopic traffic data instead of crash data. Numerous SSMs have been introduced in the literature. Now, it is somehow hard to decide about the selection of suitable SSMs for safety assessments based on microscopic traffic data. In this paper, first a review on SSMs relating to rear-end conflicts introduced in the high-quality papers is done. Then, with the help of microscopic traffic data of NGSIM in I-80 freeway, SSMs are calculated for each car-following scenario. Because of the diversity of SSMs and contradicting results it was tried to propose a method for combining the results of these indicators to report one number as the rear-end collision risk. The efficiency of the new indicator is evaluated in comparison to individual SSMs. The proposed methodology can be beneficial to improve the efficiency of In-vehicle collision avoidance warning system (IVCAWS) and enhancing highway safety evaluations based on SSMs.

关于使用追尾事故替代安全措施的修订

交通安全是交通工程研究中最重要的课题之一。人们提出了不同的安全评价方法。应用替代安全措施(SSM)预测碰撞可能性和严重程度是一种相对较新的方法，它需要微观交通数据而不是碰撞数据。文献中已经介绍了许多ssm。目前，在微观交通数据的基础上，如何选择合适的ssm进行安全评价有些困难。本文首先对高质量论文中关于追尾冲突的ssm进行了综述。然后，借助NGSIM在I-80高速公路上的微观交通数据，计算每个车辆跟车场景的ssm。由于ssm的多样性和相互矛盾的结果，试图提出一种方法，将这些指标的结果结合起来，报告一个数字作为追尾碰撞风险。将新指标的效率与个别可持续发展指标进行比较。该方法有助于提高车载避碰预警系统(IVCAWS)的效率，增强基于ssm的公路安全评价。

期刊介绍： First published in 1977 as an international journal sponsored by the International Association of Traffic and Safety Sciences, IATSS Research has contributed to the dissemination of interdisciplinary wisdom on ideal mobility, particularly in Asia. IATSS Research is an international refereed journal providing a platform for the exchange of scientific findings on transportation and safety across a wide range of academic fields, with particular emphasis on the links between scientific findings and practice in society and cultural contexts. IATSS Research welcomes submission of original research articles and reviews that satisfy the following conditions: 1.Relevant to transportation and safety, and the multiple impacts of transportation systems on security, human health, and the environment. 2.Contains important policy and practical implications based on scientific evidence in the applicable academic field. In addition to welcoming general submissions, IATSS Research occasionally plans and publishes special feature sections and special issues composed of invited articles addressing specific topics.
