Abstract

Speed is a major risk factor in overall road safety performance. The objective of this study was to identify the most frequent explanatory variables and measures used to investigate the speed factor contribution to crash injury risk (CIR). For this purpose, a literature oriented approach was used. The analysis review, underpinned by data collected from 64 journal publications reported over the past 21 years shows that speed limit was the most frequently used variable selected by the authors to investigate speed contribution CIR. Following, speed delta-V was the second most used variable, despite the barriers to access in-depth crash quality data. Even so, the speed limit was used 3.5 times more than delta-V, possibly due to the facilitate accessibility to the roads standardize posted speed limits. However, it is unknown how much vehicles travel speed could deviate from the posted speed limit at the moment of the crash.

摘要

速度是影响整体道路安全性能的主要风险因素。本研究的目的是确定用于调查速度因素对碰撞伤害风险 (CIR) 的贡献的最常见的解释变量和措施。为此，使用了以文献为导向的方法。以过去 21 年报告的 64 份期刊出版物收集的数据为基础的分析审查表明，速度限制是作者选择用于调查速度贡献 CIR 的最常用变量。紧随其后的是，速度 delta-V 是第二个最常用的变量，尽管访问深入的碰撞质量数据存在障碍。即便如此，速度限制的使用量还是 delta-V 的 3.5 倍，可能是因为道路的便利性使张贴的速度限制标准化。然而，
