Line-of-sight (LOS) sensors developed in newer vehicles have the potential to help avoid crash and near-crash scenarios with advanced driving-assistance systems; furthermore, connected vehicle technologies (CVT) also have a promising role in advancing vehicle safety. This study used crash and near-crash events from the Second Strategic Highway Research Program Naturalistic Driving Study (SHRP2 NDS) to reconstruct crash events so that the applicable benefit of sensors in LOS systems and CVT can be compared. The benefits of CVT over LOS systems include additional reaction time before a predicted crash, as well as a lower deceleration value needed to prevent a crash. This work acts as a baseline effort to determine the potential safety benefits of CVT-enabled systems over LOS sensors alone.
新型车辆中开发的视距（LOS）传感器有潜力通过先进的驾驶辅助系统帮助避免碰撞和接近碰撞的情况；此外，车联网技术（CVT）在提升车辆安全性方面也具有重要作用。本研究利用第二次战略公路研究计划自然驾驶研究（SHRP2 NDS）中的碰撞和接近碰撞事件来重建碰撞事件，以便比较LOS系统和CVT中传感器的适用效益。CVT相对于LOS系统的优势包括在预测碰撞前有额外的反应时间，以及防止碰撞所需的较低减速度值。这项工作作为一项基线研究，以确定仅配备CVT的系统相对于LOS传感器的潜在安全效益。
