The invention discloses an intersection pedestrian safety assessment method based on truck right-turn inner wheel difference blind area occupied space prediction, which comprises the following steps: constructing a truck radial distribution model and a steering angle distribution model, predicting a truck movement reachable position within a time interval T, and predicting the occupied space of a truck right-turn inner wheel difference blind area according to the truck movement reachable position; constructing a pedestrian radial distribution model and a steering angle distribution model, predicting a pedestrian motion reachable position within a time interval T, and predicting a pedestrian motion occupied space according to the pedestrian motion reachable position; and on the basis of the truck right-turn inner wheel difference blind area occupied space and the pedestrian movement occupied space, pedestrians appearing in the truck inner wheel difference blind area are predicted, and the truck-pedestrian collision risk based on the truck right-turn inner wheel difference blind area is evaluated. Potential safety hazards caused by low response speed of a driver or low sensitivity of a sensor are reduced.

    本发明公开了一种基于货车右转内轮差盲区占用空间预测的交叉口行人安全评估方法,构建货车径向分布模型和转向角度分布模型,预测时间间隔T内货车运动可达位置,由货车运动可达位置预测货车右转内轮差盲区的占用空间;构建行人径向分布模型和转向角度分布模型,预测时间间隔T内行人运动可达位置,由行人运动可达位置预测行人运动占用空间;基于货车右转内轮差盲区占用空间和行人运动占用空间对行人出现在货车内轮差盲区内进行预测,评估基于货车右转内轮差盲区的货车‑行人碰撞风险。本发明降低由于驾驶员反应速度慢或传感器灵敏度低所带来的安全隐患。
