Spoon & Tamago reports that data scientists at the West Japan Railway Company analyzed 2 years worth of information of a recurring problem: drunk people at train stations walking right off the platform and onto the train tracks.
They anticipated that the drunks just wandered aimlessly onto the tracks accidentally. But security camera footage revealed that they tended to stand up from seats and walk straight off the platform like they knew exactly where they were going.
So the train company is experimenting with a possible solution. Assuming that drunks will move in more or less a straight line after standing up, they turned seats perpendicular to the train tracks. They will see if this results in fewer drunks on the tracks in the future.
