For big events, it’s always crucial to know crowd flows and traffic on the different parts of the venue especially during the peak arrival times. Throughout the F1 race at specific times the grandstands and concert zones were in the spotlight. At each place, we placed volunteers with click counters who were counting entries and exits and sending the result to the central operator who entered the numbers to the central database through our application. The outputs of the entries are reflected on the dashboard which shows in real time the population on different parts of the venue. These dashboards are shown monitored via connected screens in the Venue Coordination Centre and mobile phones. This specific solution helps the operation team to manipulate the crowd in busy zones during peak times. Additionally, we can extract necessary statistics later, i.e. we may know the busiest times of different zones or give a specific number of how many people entered from each gate during the event.
