The invention relates to a non-motor vehicle microscopic traffic flow two-dimensional simulation method, which comprises the following steps of: constructing a self-adaptive comfortable space model of a non-motor vehicle according to measured data of the non-motor vehicle for identifying a dynamic interaction relationship of the non-motor vehicle; generating a behavior decision result of the current non-motor vehicle according to the interaction relationship, and executing he behavior so that a two-dimensional motion process is constructed; wherein the self-adaptive comfortable space is a space-time range, the threshold value of the time range is the maximum stimulation tolerance of the non-motor vehicle, and the dynamic multi-interaction relation of the non-motor vehicle at the current moment is determined by obtaining other individuals with generated stimulation exceeding the maximum stimulation tolerance. Compared with the prior art, the invention has the advantages that the influence of surrounding traffic individuals on riding is dynamically and quantitatively evaluated in real time, the multi-body interaction relation can be dynamically determined, two-dimensional plane simulation is achieved, the credibility of non-motor vehicle microscopic simulation is greatly improved, and the trueness and the test effect of virtual testing are promoted and improved.

    本发明涉及一种非机动车微观交通流二维仿真方法,包括以下步骤:根据非机动车实测数据,构建非机动车的自适应舒适空间模型,用于识别非机动车的动态交互关系;随后依据交互关系产生当前非机动车的行为决策结果并执行该行为,从而构建二维运动过程;其中自适应舒适空间为一个时空范围,其时间范围的阈值为该非机动车的最大刺激容忍度,通过获取所产生的刺激超过最大刺激容忍度的其他个体,确定该非机动车当前时刻的动态多交互关系。与现有技术相比,本发明通过实时动态量化评估周围交通个体对骑行产生的影响大小,能够动态确定多主体交互关系并实现二维平面仿真,极大地提高了非机动车微观仿真的可信度,推动和改善了虚拟测试的真实度和测试效果。
