Abstract

Abstract The current paper proposes a data analysis method to evaluate the impact of vehicle-technology evolution on road safety based on a recent and extensive accident dataset (1.3 million vehicles in 2017 and 1.7 million in 2018, Italy). Seventeen models of vehicles equipped with an event data recorder were selected for acquiring data, including the distances travelled by the vehicles during the year, and were aggregated by their year of initial registration and model. This unique information in conjunction with the accident datasets enabled a consistent estimation of risk exposure and accident rates for various subsets of vehicles. Thereafter, the comparative analysis of accident rates revealed an improvement in the road safety along with a significant variation between various vehicle models that approximately ranged from 5–10 accidents per million kilometres. Moreover, the accident rate reduced after the electronic stability control system was mandated for vehicles in the market, exhibiting variations in the range of 15–30% for serious accidents that were dependent on the vehicle model. Further safety improvements were identified for the latest generation of vehicles equipped with more advanced technologies such as the autonomous emergency braking that can reduce the accident rate up to 38%.

安全系统和车辆世代:使用事件数据记录器收集的事故和旅行数据分析
本文提出了一种数据分析方法,以评估车辆技术发展对道路安全的影响,该方法基于最近和广泛的事故数据集(2017年为130万辆,2018年为170万辆,意大利)。选取了17种配备事件数据记录器的车辆型号来收集数据,包括车辆在一年内行驶的距离,并按首次登记年份和型号汇总。这种独特的信息与事故数据集相结合,可以对不同车辆子集的风险暴露和事故率进行一致的估计。此后,对事故率的比较分析显示,道路安全有所改善,各种车辆型号之间的差异很大,大约每百万公里发生5-10起事故。此外,在市场上的车辆强制安装电子稳定控制系统后,事故率降低了,根据车辆型号的不同,严重事故的事故率在15-30%之间。最新一代车辆配备了更先进的技术,如自动紧急制动,可将事故率降低38%,从而进一步提高了安全性。
