摘要
为深入研究高速公路微观换道行为的决策过程,提高高速公路换道模型的真实性和有效性,将任意换道行为分为向左侧换道行为和向右侧换道行为,引入驾驶员性格影响因子和车辆类型参数,基于模糊逻辑推理构建任意性换道行为模型;同时,为增强换道行为的动态效果,构建高速公路自由状态下车速控制模型和跟车行为模型.仿真结果显示该任意性换道模型具有较好的真实性和有效性,表明向左侧换道行为模型和向右侧换道行为模型能准确反映高速公路微观换道行为的决策过程.
To deeply investigate the decision making for microscopic lane-changing behaviors on freeway,and to improve the authenticity and effectiveness of corresponding lane-changing models,discretionary lane-changing behaviors were divided into leftward and rightward lane-changing behaviors in this research; with the factors that impact drivers' characteristics and vehicle type parameters introduced into the research,a discretionary lane-changing model was established based on fuzzy logic. Meanwhile,vehicle speed control models under the free state and vehicle following models were built to enhance dynamic effects of lane-changing behaviors. The simulation results suggest that the discretionary lanechanging model is highly authentic and valid. According to the research,both the leftward and rightward lane-changing models can accurately reflect the decision making for microscopic lane-changing behaviors on freeway.
