A crash prediction and prevention method was proposed to detect imminent crash risk and help recommend traffic control strategies to prevent crashes. The method consists of two modules, the crash prediction module and the crash prevention module. The crash prediction module detects crash-prone conditions when the predicted crash probability exceeds a specified threshold. Then the crash prevention module would simulate the safety effect of traffic control alternatives and recommend the optimal one. The proposed method was demonstrated in a case study with variable speed limit (VSL). Results showed that the proposed crash prediction and prevention method could effectively detect crash-prone conditions and evaluate the safety and mobility impacts of various safety countermeasures.
提出了一种碰撞预测和预防方法,以检测即将发生的碰撞风险,并帮助推荐交通控制策略以防止碰撞。该方法包括两个模块,碰撞预测模块和碰撞预防模块。当预测的碰撞概率超过指定阈值时,碰撞预测模块会检测到易发生碰撞的情况。然后,碰撞预防模块将模拟交通控制替代方案的安全效果,并推荐最佳方案。在所进行的带有可变限速(VSL)的案例研究中验证了所提出的方法。结果表明,所提出的碰撞预测和预防方法可以有效地检测易发生碰撞的情况,并评估各种安全措施的安全性和机动性影响。
