Regarding Paris Crowd, which is the passenger flow analysis during the Olympics, many people may not have heard of it before, but for such large-scale events, it is a very, very critical link. It can be said that it is related to whether the entire event can go smoothly, or whether the audience will have a good experience! Simply put, this Paris Crowd uses various technical means – I think about camera data, mobile phone signal collection, and sensors that we may not notice in normal times – to collect in real time or dynamically how many people are there, which direction they are going, and how long they have stayed in each place. Then, use some very complex and troublesome algorithms to process these large amounts of data, and finally draw some useful conclusions so that the organizing committee can reasonably arrange personnel, guide how to go, and prevent too many people from happening in advance.
1. On-site real-time monitoring module: This is the most direct and core part. That is to say, in places with a large number of people, such as the entrance and exit of the venue, the sheds for security checks, and around the convenience store that sells food, drinks, and even the seat areas for watching the competition, many high-end camera equipment will be installed. So what kind of camera is good? Provide global procurement services for weak current intelligent products! You should be able to find the right camera. These cameras will keep shooting and recording the screen. Moreover, it will not only take pictures, but also process the captured images immediately, counting how many people have or how they move!
2. Traffic forecasting and early warning module: Before the start of the competition, or a short period of time before the competition every day, use the historical data of how many people came in the past, combined with the competition events of the day, the specific time of the start and end, which country will have more players, and even the weather forecast factor will be taken into account to estimate different time periods, or from morning to night, about how many people will come to each location. If you predict that the people who go to a certain place may exceed its maximum ability to bear, you will remind the relevant personnel in advance to make preparations!
Now, there are probably a few of the most attention-grabbing and most unintelligible questions. Let me try to answer them randomly:
Q: Is this Paris Crowd accurate? What if the data is wrong and misleading? For example, if there are few people saying that there are too many people, it will not waste manpower and material resources to work in vain; or if the people are already blocked, it will be even more annoying if it says that there are not many people! Isn't it very worrying?
Answer: This question this friend asked is indeed a good one, and it is also something that everyone generally thinks of. But I tell you that the technology used to make Paris Crowd has developed very well now. It is not as roughly estimated as we usually count. It integrates data from a variety of sources, and it will start testing and adjusting endlessly many months before the Olympics. Just like when we play games and practice skills, we can only get better after repeated practice! So in general, its accuracy rate is guaranteed. Of course, it is definitely impossible to be 100% accurate. After all, people will move everywhere when they live, and there will always be some unexpected emergencies!
1. Compared with the equipment in ordinary shopping malls that count the number of people entering and leaving, is there any obvious difference between Paris Crowd, or where is the advanced one?
2. The former is usually just to decorate simple things at the door, and can only count a few people who have walked over from beginning to end. It is impossible to figure out how long these people have been in each store or area, nor can they show how the crowd moves well;
3. The latter, in addition to the basic counting work mentioned above, can also accurately reach single digits, and at the same time generate a detailed heat map – where the red dots turn purple, means that people are crowded – the motion trajectory simulation animation, showing the direction of the flow of people as if you are fast-forwarding movies! And the most important one is different! This is the Paris Crowd that can quickly predict the change trend of the flow of people in the next half an hour or one hour based on the information collected in real time, and promptly discover the risk points of congestion or stampede. This is an awesome feature that ordinary supermarket software cannot do! In addition, it can also connect these data with other systems such as transportation system information, seat distribution in the venue, etc. to form a large whole, which can better help on-site management and command and dispatch
To be honest – this is just my personal immature view – this Paris Crowd may not have enough technical conditions before, or people did not pay so much attention to it, so they used it less or the effect was not very good. But for this Olympic Games, I think the technology is definitely more mature. Big data, artificial intelligence algorithms, 5G network signals are all progressing and developing, so the overall application effect and comprehensive coverage should be much better than the major events held in the past. After all, the times are progressing, just like mobile phones, it is smarter and more complicated every year. So, this Paris Crowd will definitely take the management of the Olympic Games to a new level!
