摘要
车辆的行驶受到本车道以及邻近车道前后邻近车辆的影响,在城市交通中机非混合对车辆行走的影响尤为复杂。通过研究路段上机非混合通行交通流的本质特性,综合考虑非机动车对机动车换道规则及加减速规则的"摩擦"和"阻滞"干扰影响,建立描述路段混合通行道路交通流的元胞自动机(CA)模型,从不同的机非混合比例下道路交通流的流量、速度变化情况,流量与车辆到达率关系,交通流相位相变等方面仿真模拟混合交通流的机非干扰机理。
The running of vehicle is influenced by the vehicles of the driveway and the front or the later vehicles of the adjacent lanes. In city traffic,the impact of mixing motor vehicles and non-motor vehicles on the running of vehicle is particularly complex. Through the research on the essential characteristics of mixed traffic flow,considering the＂friction＂and＂blocking＂interference of non-motor vehicle on the motor vehicles in lane changing rules and the acceleration and deceleration rules. The cellular automata（ CA） model describing the mixed traffic is proposed,and numerical simulatings show the basic law of mixed traffic flow fundamental diagram when the non-motor vehicles and motor vehicles blended in different ratio.
