针对中国城市交通以机动车、非机动车和行人所组成的混合交通流为主的现状,用连续微观仿真模型进行仿真将能够更加真实地描述交叉口机非混合流系统的复杂性.本文对一种基于交叉口冲突点检测方法的新型连续微观仿真模型进行了简单介绍,并针对该模型提出了详细的计算机仿真实现方法.之后,针对典型的机非混合交叉口给出了详细的仿真算例,并与实际观测值进行了比较分析.结果表明,仿真数据对于观测数据具有很好的拟合度,从而表明该仿真模型能够较好地反映机非混合交叉口系统的真实复杂特性.

In view of the current phenomena that the traffic flows in China are always heterogeneous mixed with motorcycles, non-motorcycles, and pedestrians, the continuous microscope simulation model is used to reflect the complexity of the intersection system with heterogeneous mixed flows. This paper introduces a conflict-point detection model (CD) which belongs to a new type of this kind of model, and then presents its detailed simulation method. Then, a simulation example of a classic Chinese intersection is given and compared with the observe values. The good degree of fitting shows that the CD model can reflect the complexity of intersection filled with heterogeneous mixed flows in China very well.
