NTT Docomo Inc. made a computer simulation visualizing what would happen if 1,500 pedestrians walked across the famous crossing in front of Shibuya station in Tokyo while texting: only 36% would make it across safely.
The pedestrians are color-coded by departure point and walk at 3, 4, or 6 km/h. They all have average height and weight, i.e., 160 cm resp. 58 kg. The model further assumes that texting reduces the vision range by 80% to 1.5 m. The green light lasts 46 seconds.
The result shown in the simulation is that only 547 pedestrian crossed without accidents. The others collided and either had to stop to apologize, fell, or dropped their phones.
