交通仿真技术的广泛应用,提高了方案预测的准确性和实时再现性。在以模拟机动车为主的仿真软件不能较好满足国内混合交通的背景下,非机动车跟驰模型的研究尤为重要。论文首先参照机动车定义了非机动车的虚拟行车道,提出了跟驰状态的判断条件,以此作为非机动车跟驰行为的研究基础。其次,以车辆间应保持的最小安全车头间距为思路,充分考虑非机动车中电动自行车与自行车之间的差异,构建了非机动车的跟驰模型。最后,将模型所涉及的参数与宏观的交通流参数联系起来,通过流量、速度和密度关系,验证了模型的有效性。研究对于完善现有的交通仿真软件具有一定的参考和实用价值。

Traffic simulation is widely used to forecast and assess traffic engineering scenarios for it can improve the forecast accuracy and make scenarios visualization in real-time. Now, the foreign simulation softwares based on motor vehicle behaviors can not wellmatchthemixedtraffic of China, so research of anon-motorizedvehicle-followingmodel is particularly important. Firstly, this paper defined a virtual lane of a non-motorized vehicle by imitating the motor vehicle lane, and presented the condition to judge the following status of the non-motorized vehicle as a foundation for studying the non-motorized vehicle behavior in the following. Secondly, with the idea to maintain the minimum security headway, the paper estahlished a non-motorized vehicle-following model. Finally, combining the model parameters with the macroscopic traffic flow parameters, and according to the relationship among traffic flow, velocity and density, the paper certified and validated the above model.
