Whenever there is a bigger event occurring in a city, there will be a need to manage the security of the crowd. The attendance of a certain event may be difficult to predict and you may need to make adjustments as the visitor count deviates from what was predicted.
By having access to real-time analytics on the flow of people to any particular event, you will be able to make relevant decisions at an earlier point in time. This will increase the security and make the event more pleasurable for everyone. You may also want to limit the number of visitors for fire safety reasons.
