Mitsubishi Electric Develops World’s First Real-time
Crowd-congestion Estimation System
Promises to enhance crowd safety and operational efficiency at large eventsTOKYO, August 18, 2016 – Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has
jointly developed what is believed to be the world’s first* system that analyzes data from surveillancecameras for high-accuracy real-time estimation and prediction of crowd congestion on pathways to and fromevent sites, working in collaboration with the Research Center for Advanced Science and Technology ofTokyo University (RCAST). As a solution for effectively managing crowd congestion based on highly
accurate prediction, it is hoped that the technology will contribute to increased visitor safety and security atevents. Mitsubishi Electric will conduct a field demonstration of its new system at the 38th Tamagawa
Fireworks Festival in Tokyo, Japan on August 20.

The system is the world’s first simulator of real-time crowd movements. Its 80 percent accuracy rate isapproximately 30 percent higher than that of conventional methods. Using data from surveillance cameras toestimate and predict crowd movements in real time, the system is a practical solution for relieving crowdcongestion on pathways to and from event sites. Also, it greatly reduces computational complexity compared
to conventional methods thanks to RCAST’s high-speed human-behavior model for simulating crowd
movements by focusing not on the complete crowd but nearby people.

Mitsubishi Electric’s new system will provide event organizers with a practical means for reducing crowdcongestion to maintain event pathways. Since areas in risk of excessive congestion can be estimated in realtime, crowd-management countermeasures can be carried out in advance. The results are increased visitor
safety, more secure event management and more efficient crowd-management operations.

Background
Events that experience high influxes of people present significant concerns for crowd safety, often requiring
event organizers to drastically increase personnel needed to ensure sufficient safety and cover wide areas
around event sites. Conventional technologies for estimating crowd congestion use historical data on crowd
flow rates, but this involves highly complex computations and is not sufficiently accurate.

Patents
Pending patents for the technology announced in this news release number 11 in Japan and nine abroad.
