交通瓶颈对车辆交通的影响

Effects of Bottlenecks on Vehicle Traffic

Syohei Yamamoto, Yasuhiro Hieida, Shin-ichi Tadaki

摘要:

交通挤塞通常出现在瓶颈地带的上游,例如隧道。拥挤表现为走走停停的波浪和高密度的均匀流。我们使用耦合地图最优速度模型对具有瓶颈的交通流进行了模拟。瓶颈被表示为具有速度降低的路段。瓶颈中的速度降低控制了走走停停波的出现。建立了瓶颈效应的唯象理论。

英文摘要:

Traffic congestion is usually observed at the upper streams of bottlenecks such as tunnels. Congestion appears as stop-and-go waves and high density uniform flow. We perform simulations of traffic flow with a bottleneck using the coupled map optimal velocity model. The bottleneck is expressed as a road segment with speed reduction. The speed reduction in the bottleneck controls the emergence of stop-and-go waves. A phenomenological theory of bottleneck effects is constructed.
