The invention discloses a signal intersection entrance lane vehicle passing model based on risk quantification. The signal intersection entrance lane vehicle passing model is used for describing a decision behavior and a motion process of a vehicle passing through an intersection entrance lane stop line during a yellow light period. According to the method, the signal lamp risk field model independent of the yellow lamp duration is constructed by establishing the space and time change characteristic function of the signal lamp risk, and the risk value applied by the signal lamp and borne by the vehicle in the passing process of the signal intersection entrance road section is quantified. On the basis, a signalized intersection entrance lane vehicle passing model meeting the expected risk of the driver is constructed. Compared with the existing model, the traffic behavior of the vehicle at the entrance road section of the signalized intersection can be explained from the angles of human risk perception and behavior mechanism, and theoretical support can be provided for humanization decision and control of the automatic driving vehicle.
本发明公开了一种基于风险量化的信号交叉口进口道车辆通行模型,用于描述车辆在黄灯期间通过交叉口进口道停车线的决策行为和运动过程。本发明通过建立信号灯风险的空间和时间变化特征函数,构建了不依赖于黄灯时长的信号灯风险场模型,量化了车辆在信号交叉口进口道路段通行过程中承受的由信号灯施加的风险值。在此基础上,构建了满足驾驶人期望风险的信号交叉口进口道车辆通行模型。与已有模型相比,本发明能够从人类风险感知和行为机理的角度解释车辆在信号交叉口进口道路段的通行行为,并能够为自动驾驶车辆的类人化决策和控制提供理论支撑。
