考虑驾驶心理的机非冲突行为研究

Study on the Conflict Behavior Between Vehicles and Bicycles Considering Driving Psychology

针对信号交叉口右转机动车与直行非机动车的冲突问题,对机非的行为特性进行分析。根据非机动车绿灯初期的释放特征,建立膨胀度模型,并对比不同信号灯类型下的膨胀度。从驾驶心理的角度,分析机非的驾驶风格。通过视频拍摄和图像处理的方式,提取了上海市控江路-隆昌路交叉口右转机动车在非机动车影响下的通过交叉口各时段的平均速度。对右转机动车通过冲突区的速度采用K-均值聚类分析将驾驶员划分为谨慎型、稳健型和激进型,并分析受直行非机动车影响下右转机动车的速度与轨迹。

Aiming at the conflict between right turning vehicles and straight bicycles at signalized intersections,the behavior characteristics of vehicles and bicycles were analyzed.According to the initial release characteristics of green light of non-motor vehicles,an expansion model was established,and the expansion degrees of different signal types were compared.From the perspective of driving psychology,the driving style of vehicles and bicycles was analyzed.Through video capturing and image processing,the average speed of right turning vehicles passing through the intersection under the influence of bicycles at the intersection of Shanghai Kongjiang Road and Longchang Road was extracted.K-means clustering analysis was used to classify drivers into cautious,robust and radical type for the speed of right turning vehicles passing through the conflict zone,and the speed and trajectory of right turning vehicles under the influence of straight bicycles were analyzed.
