从冲突避让的角度对城市交叉口内机动车驾驶员的穿越行为进行了分析,应用场图工具研究了驾驶员在进行车流穿越时的决策过程,提出了有异于可接受间隙模型的、基于占先度的驾驶员冲突避碰决策模型。利用实地采集的数据对驾驶员的临界占先度阈值的分布参数进行了标定,并通过科尔莫戈罗夫验证法进行统计学假设检验。分析结果表明:437组实地冲突样本中,有82.2%的驾驶员决策行为为正常决策,17.8%的决策行为为异常决策,说明驾驶员在决策过程中存在一个临界的心理占先度,并且驾驶员的临界占先度阈值服从正态分布N(0,0.22)。
From the perspective of conflict avoidance, the crossing behavior of motor vehicle drivers in urban intersections was analyzed. The field map tool was used to study the decision-making process of drivers when they were passing through the vehicle. Proposed different models based on preemptive gap Degree Driver Collision Avoidance Decision Model. Using the data collected in the field, the distribution parameters of driver’s threshold of preemptiveness threshold were calibrated and statistically tested by Kolmogorov’s test. The analysis results show that: Among the 437 field conflict samples, 82.2% of the driver decision-making behavior is normal decision-making, 17.8% decision-making behavior is abnormal decision-making, indicating that the driver has a critical psychological precedence in the decision-making process, and the driver The threshold of critical preemptive degree obeys normal distribution N (0,0.22).
