Unfortunately, highway traffic jam and traffic interruption and traffic delay, which caused by disaster weather, bad traffic status and traffic events, are becoming more and more serious.
但因灾害性天气、不良交通状况和交通事件等引发公路交通拥挤、交通中断和交通延误以及伤亡惨重的交通事故也随着路网里程的增多而增加。
So it's not necessarily the volume of traffic, but rather a sudden interruption in the flow that causes delays.
所以说，造成阻塞的不一定就是车流量大小，而是会在车流中引起延迟的突然中断。
