NEC as Tokyo deployed the world’s first comprehensive disaster prevention system based on behavior analytic
IT& NEC communications world leaders in recent days as Japan Toshima-Ku Tokyo has deployed “Toshima-Ku comprehensive disaster prevention system”, is the world’s first early by analyzing crowd behavior to predict whether there is a special condition of disaster prevention system. It is reported that the system will be launched in May 2015, officially put into use beginning in June.
Toshima-Ku Tokyo is crowd-intensive areas, after Japan 3.11 after the earthquake, the local government established the “basic policy on comprehensive disaster prevention”, and actively implement the disaster countermeasures basic act to strengthen capacity-building for disaster prevention. For example, 3.11 earthquake caused by public transport stopped in the traveler from home and stays in the transport hub of Ikebukuro station and its surrounding area of confusion,, Toshima introduced the “Toshima-Ku to House those countermeasures plan”, and won “movement WHO Regional Security Center” promoting “safe community certification”.
The local Government hopes that the new system, before the natural disaster as well as General accident has occurred, as early as possible through various clues can acquire the relevant developments in order to evacuate the affected people in the first time, to prevent Stampede in crowded areas, such as.
To this end, NEC in this “comprehensive disaster prevention system,” importing a self developed “crowd behavior analysis technology”, prior to applying the surveillance cameras on the unusual degree of public confusion and the immigrant flow anomalies, such as high precision to be considered through the crowds early to predict abnormal changes in behaviour of the whole.
NEC “crowd behavior analysis technology” based on image recognition technology developed from, even if the figure overlapped scenes of chaos, but also dynamic high-accuracy analysis of the overall behavior of the crowd, quickly gives mixed flow levels, and the crowd of early judgment. Also, when an exception occurs, you can automatically alert notice to the related people, which not only greatly reduces the workload of monitoring Department duty personnel, first time and enable relevant departments at all levels to grasp the situation so as to make quick countermeasures such as help or inform.
In addition, passenger throughput reached 2.59 million passengers a day around Ikebukuro station and other major stations, main road, rescue centres, schools and other places of refuge 51 new webcam for disaster prevention, surveillance video from Toshima-Ku Center for disaster response management, and give information to the affected population in a timely manner. Hazard information will be rendered on the map screen, more visually easy to understand and greatly improves the speed of decision making, creates conditions for the clock transfer security of life and property.

In crowded public spaces and large public facilities if chaos is easily derived Stampede, or become the target of attacks by criminals. In public facilities set up to prevent such cameras to nip the danger can be reduced to a minimum.
NEC has been is committed to in global promotion security, and assured, and efficient, and fair of social based facilities solution programme, which involving security field of “SaferCities” solution programme has in global more than 40 multiple national import 500 sets above system, this for Tokyo Toshima-Ku deployment of “crowd behavior parsing technology” future also will in crowd intensive of station, and airport, and theme park, and large stadium Museum, and large exhibition, variety scene played role.
