Regarding the accident where a truck and a train collided with each other at a railroad crossing on the Keikyu Line in Yokohama City, the Japan Transport Safety Board needs to properly position and number traffic lights to prevent recurrence. We have compiled a survey report that states that.
In September, a truck collided with a truck that was stuck at a railroad crossing on the Keikyu Line in Kanagawa Ward, Yokohama City, and police said that a man driving the truck died and more than 30 people including train passengers were injured. I did.
According to the investigation report compiled by the Japan Transport Safety Board, it is extremely within 1.8 seconds after the train driver reaches the place where the traffic light indicating the abnormality in the railroad crossing can be seen while driving at 120 km / h. It is estimated that the brakes had to be applied, and it is probable that the time required for the driver to check the traffic lights was not fully considered.
In reality, it was estimated that it took about 4 seconds to notice the blinking and apply the brakes due to the blinking speed of the signal and the pillars that momentarily block the signal.
For this reason, he concluded that it would have been difficult for the driver to react immediately to the traffic light because he had passed the place where he could stop by the railroad crossing.
In addition, the operation of the brakes was entrusted to the driver, who first applied the regular brake and then used the emergency brake.
For this reason, in order to prevent recurrence, it is necessary to properly arrange the position and number of traffic lights, and it is desirable to specify the operation method of the brake concretely, and Keikyu Corporation has already taken measures to prevent recurrence. about it.
