Have you ever been trapped in a traffic jam even when there are no signs of any accidents or roadwork? This strange phenomenon is known as a phantom traffic jam. It is caused by minor changes in traffic flow like sudden braking. When a driver brakes on a busy highway, each driver behind him or her in the line of traffic then hits their brakes as well. This results in a wave of braking that can continue for kilometers. However, this situation is much less likely to happen on less crowded roads.

  即使沒有任何事故或道路施工的跡象,你是否也曾被困在車陣之中?這個奇怪的現象被稱為幽靈塞車。它是由像急煞等車流中的微小變化所引起的。當一名駕駛在繁忙的高速公路煞車,在其後車陣中的每一位駕駛也會接著踩煞車。這導致可以持續數公里的一波波煞車潮。然而,這種情況在較不壅塞的路上發生的可能性小很多。
