在美国,大约每年都会有3500起公路铁路的相撞事故,约占2004年全美铁路死亡事故总数的95%。最普遍的事故是火车与驶入轨道的汽车相撞。此类事故的原因在于火车无法及时安全停止。高速运行的客运列车及低速运行的货运列车均需在几千米之外发出警报方可使火车及时停止。即便火车驾驶员能够充分减速,这种做法也极有可能引起火车脱轨,导致比撞车更严重的破坏与伤害。基于这一限制,多数事故防御措施的有效性均取决于汽车的驾驶员。如果
In the United States, about 3,500 road-railway collisions occur each year, accounting for about 95% of the total number of U.S. railroad deaths in 2004. The most common accident is a train colliding with a car that has orbit. The reason for such an accident is that the train can not be safely stopped in time. High-speed passenger trains and low-speed freight trains are required to issue an alarm a few kilometers away in order to stop the train in time. Even if the train driver can slow down sufficiently, this practice is also highly likely to cause the train to derail, resulting in more serious damage and damage than the crash. Based on this limitation, the effectiveness of most accident prevention measures depends on the driver of the car. in case
