摘要

道路安全是道路运输的一个重要方面。公路安全评价有助于工程师确定安全改进的优先顺序，并评价改进措施的有效性。碰撞预测模型是评价公路要素安全水平的重要工具。许多研究报告了几何形状和交通因素对简单(单一)水平弯道安全的影响。但当出现多个水平曲线时，情况就变得更加复杂。公路安全手册也没有提供多个水平弯道的安全性能函数。因此，本研究旨在量化前弯道几何特征对碰撞的影响，并建立双车道非城市道路上多水平弯道安全性能评估模型。本研究所需的数据包括102条多水平弯道的碰撞、几何和交通数据。

Safety evaluation of multiple horizontal curves using statistical models

Road safety is an important aspect of road transportation. Safety evaluation of highways helps engineers in prioritising them for safety improvement and for evaluating the effectiveness of the improvement measures. Crash prediction models are very useful for evaluating the safety levels of highway elements. Many studies reported the effect of geometry and traffic factors on safety at simple (single) horizontal curves. But the situation becomes more complex when multiple horizontal curves occur. The Highway Safety Manual also does not provide a safety performance function on multiple horizontal curves. Hence, this study aims to quantify the influence of geometric characteristics of the preceding curve on crashes and develop models for evaluation of the safety performance of multiple horizontal curves on two-lane non-urban roads. The data required for this study include crash, geometric, and traffic data from 102 multiple horizontal curves.

期刊介绍： The IJVS aims to provide a refereed and authoritative source of information in the field of vehicle safety design, research, and development. It serves applied scientists, engineers, policy makers and safety advocates with a platform to develop, promote, and coordinate the science, technology and practice of vehicle safety. IJVS also seeks to establish channels of communication between industry and academy, industry and government in the field of vehicle safety. IJVS is published quarterly. It covers the subjects of passive and active safety in road traffic as well as traffic related public health issues, from impact biomechanics to vehicle crashworthiness, and from crash avoidance to intelligent highway systems.
