蜿蜒路段经常成为高架道路上的瓶颈。基于NS元胞自动机交通模型，对单车道主干道交织路段进行了仿真分析。对于自由交通流，即使增加编织长度，编织对系统几乎没有影响。另一方面，当交通流处于拥塞状态时，编织冲突会对系统产生负面影响。随着编织长度的增加，交通状况将得到改善。我们的模拟结果表明，不需要不适当地增加编织段的长度，而应该选择适当的适度值以获得最佳的交通状况。
The weaving sections often turn into the bottleneck on the elevated roads. On the basis of the NS cellular automaton traffic model, the weaving section with one-lane main road was simulated and analyzed. For the free traffic flow, weaving almost has no influence on the system, even with increased weaving length. On the other hand, when the traffic flow is in congested state, weaving conflicts have negative effects on the system. The traffic condition will be improved with the increase of weaving length. Our simulation results suggest that the length of weaving sections need not to be inappropriately increased, and a proper moderate value should be chosen to get an optimal traffic condition.
