Abstract

While overall crash statistics have been declining, collisions involving cyclists and pedestrians have not decreased at the same rate, particularly in urban areas. To enhance the safety of these vulnerable road users (VRUs), advanced driver assistance systems (ADAS) are being developed and introduced to the market. These systems aim to prevent or mitigate crashes by alerting drivers in critical situations and, if necessary, automatically applying braking or steering interventions.

This study evaluates the effectiveness of a new autonomous emergency braking and steering (AEB + S) system in reducing fatalities and serious injuries in car-to-VRU collisions on urban roads across Europe. A prospective safety performance assessment was conducted using virtual simulations.

The results indicate that AEB alone already prevents most crashes and VRU fatalities and serious injuries in urban VRU-crossing scenarios. The additional safety benefit of AEB + S compared to the baseline AEB system is relatively small—less than 1 % for VRU-crossing crash cases. However, AEB + S proves advantageous in scenarios where the VRU becomes visible too late for AEB alone to act, and an in-lane avoidance manoeuvre is feasible.

These findings provide valuable insights for policymakers and regulatory bodies in assessing the real-world benefits of emerging ADAS technologies.

汽车与vru碰撞时新型AEB和AES的安全性能评估

虽然总体撞车统计数据一直在下降，但涉及骑自行车者和行人的碰撞并没有以同样的速度下降，尤其是在城市地区。为了加强这些易受伤害的道路使用者（vru）的安全，先进驾驶辅助系统（ADAS）正在开发和推向市场。这些系统旨在通过在紧急情况下提醒驾驶员，并在必要时自动应用制动或转向干预措施，防止或减轻碰撞。本研究评估了一种新型自动紧急制动和转向（AEB + S）系统在减少欧洲城市道路上车辆与vru碰撞造成的死亡和严重伤害方面的有效性。使用虚拟模拟进行了前瞻性安全性能评估。结果表明，仅AEB就可以防止城市VRU穿越场景中的大多数碰撞和VRU死亡和严重伤害。与基线AEB系统相比，AEB + S系统的额外安全效益相对较小，在vru穿越事故中不到1%。然而，AEB + S被证明在VRU变得太迟而无法单独行动的情况下是有利的，并且车道内避免机动是可行的。这些发现为决策者和监管机构评估新兴ADAS技术的实际效益提供了有价值的见解。

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.
