Japan is a country where vehicles drive on the left, but pedestrian traffic on roads is unclear.

Pedestrian traffic in train stations, commercial facilities, event facilities, etc. is not defined and there is no unified design philosophy.

As a result, pedestrian confusion occurs on roads and facilities, resulting in congestion and accidents due to reduced capacity.

Large-scale events attract a large number of spectators from all over the world, but the traffic methods differ from place to place and the measures to prevent pedestrian accidents are not well known, which can lead to confusion during normal times and cause accidents in the event of a sudden incident.

During large-scale events with large crowds of people, the risk of accidents of crowds is always inherent, so it is necessary to understand the principles of crowd behavior and to take soft and hard measures for crowd control based on this knowledge.

It is also important to take measures at normal times, to develop the habit of crowd behavior and to provide accurate guidance in order to accurately guide crowds during large-scale events and to evacuate people in the emergency such as earthquakes and terrorist attacks.
