用NS模型和EBCA1模型分别描述机动车流和自行车流的行为,用摩擦干扰和阻滞干扰体现自行车对机动车的干扰作用,建立了自行车干扰下机动车交通流模型并利用数值模拟研究了其行为,并通过与实测数据的对比证明了模型的合理性.通过分析仿真数据发现,机动车流受到的主要干扰形式取决于两种车流的密度.自行车的干扰主要影响到低密度的机动车流,使其流量、速度都有较明显降低.同时,机动车流中阻塞的发生更加频繁但持续时间较短.
Using the NS model and the EBCA1 model to describe the flow of motor flow and bicycle flow, respectively, the frictional interference and blockage interference reflect the bicycle’s interference to the motor vehicle. A traffic jam model of the automobile with the bicycle disturbance is established and its behavior is studied by numerical simulation , And compared with the measured data to prove the rationality of the model.According to the simulation data, it is found that the main interference form of the motor flow depends on the density of the two kinds of traffic flow.Bicyclists mainly affect the low-density flow of vehicles, Traffic, speed are significantly reduced.At the same time, motor vehicle traffic jam occurred more frequently but the duration is shorter.
