Here is a computer simulation of 1500 people crossing the street at Shibuya Crossing in Tokyo Japan while looking down at their cell phones.
simulation – a situation where a set of conditions is created artificially in order to study or experience something that could exist or happen in reality.
The text in the video is in Japanese but there is an English translation of the results of the simulation below the video plus a link to the original article.
What would happen if 1,500 pedestrians walked across the famous crossing in front of Tokyo’s Shibuya Station while using their smartphones?
Only 36 percent would make it to the other side because many would bump into each other or fall, according to a computer simulation by NTT Docomo Inc. that is generating a buzz on the Internet. (becoming popular)
As the trend in texting while walking grows, the carrier decided to study how much danger pedestrians were risking, it said. The simulation set up 1,500 people walking at speeds of 3, 4 or 6 kph. Each simulated pedestrian was 160 cm tall and weighed 58 kg, the median (average) for Japanese.
It assumed that pedestrians who text while walking have a range of vision one-twentieth (1/20th) that of normal, so they cannot see obstacles until they are 1.5 meters away. Pedestrians who fail to avoid a collision either apologize, fall down or drop their phone.
The pedestrians had 46 seconds to cross before the signal turned red.
The result of the simulation was that there were 446 collisions leading to 103 cases of falling and 21 dropped phones. Only 547 pedestrians crossed without incident (a problem).
