heavy traffic flow

Concrete repairs under heavy traffic flow remains a difficult problem in highway maintenance.

在高交通流量下砼的修补是公路养护部门的一大难题。

However, at lower discount rate and heavy traffic flow the initial cost of construction is in essence irrelevant.

然而，在折限率较低与交通量大的情况下，从本质上讲，与建设的最初成本没有关系。

At the same time, a single intersection traffic flow model is proposed to reflect the light traffic and heavy traffic and describe the queue length.

同时提出单交叉口的交通流量模型，使其能同时反映轻度交通和重度交通，能够描述排队长度。
