拥堵交通呈现出非常复杂和随机的特征。最有趣的特征之一是扰动的放大/衰减，表明下游的小速度振荡发展为上游的大速度振荡。虽然交通理论试图解释这一现象，但从驾驶员行为的角度来看，速度振荡的机制尚不清楚。类似的现象也出现在体育场、剧院售票亭前等长队中。本文对比车辆运动更容易理解的排队等候中走走停停的运动进行了建模和仿真。通过仿真发现，在等待队列中存在扰动的放大/衰减，并且表现出与车辆运动相似的模式。
Congested traffic shows very complicated and stochastic features. One of the most interesting features is the amplification/decay of perturbations, indicating the development of small speed oscillation in the downstream into the large speed oscillation in the upstream. While traffic theories attempt to explain this phenomenon, the mechanism of the speed oscillation is not yet clear in the aspect of drivers’ behavior. Similar phenomenon is also found in a long waiting line such as in front of the stadium or theater ticket box. In this paper, the stop-and-go movement in the waiting line, which is relatively easy to understand than the vehicular movement, is modeled and simulated. From the simulation, it is found that the amplification/decay of perturbation exists in the waiting line and shows similar pattern as in the vehicular movement.
