A Review on Surrogate Safety Measures in Safety Evaluation and Analysis

Abstract

AbstractRoad traffic safety has become a major problem, despite developments in technology and infrastructure. Traditionally, road safety is measured using accident data, which is essentially considered a reactive approach, although this method has time and efficiency limitations. Using surrogate safety data allows for a faster evolution of safety than using long-term accident data, according to previous studies. This paper presents an overview of the current surrogate safety measures (SSMs) that explicitly focuses on the potential to analyze vulnerable road users and the areas that previous studies have ratified. In a compressive and quantitative manner, the scope analysis explored how surrogate safety measures (SSMs) have been applied so far in scientific literature and what are their key drawbacks. This study will also help to identify new ideas in this field and identify recommendations for research leading to the emergence of a new use of surrogate safety measures.KeywordsRoad safetySurrogate safety indicatorsTraffic conflict techniqueMicro-simulation
