Passenger’s mobiles and smartphones provide accurate statistics
Efficient airport operations need accurate planning tools. For many years, measuring passenger behavior has been crucial to schedule correct numbers of staff at specific locations, at specific times.
How many security agents will be needed on March 19 at the security screening platform of pier A between 10 and 11 am? How many employees should staff the coffee counter in the departures hall at midnight? How many airport trolleys are needed in the baggage reclaim area on an average Friday night between 8 and 10 pm? What are the waiting times at the security screening at this exact moment, measured in minutes per passenger? This sort of information is vital to provide correct staff scheduling for many sorts of airport jobs, and to warn passengers about their waiting times at specific areas. It allows airport shops, bars and restaurants to place their orders and replenish their shelves for the coming days and hours.
For decades, airports have discretely measured passenger's behavior. With chronograph and counter in hand, walking patterns of specific anonymous passengers are measured to chart typical behavior patterns at each time of day. Passengers are counted and recounted, per hour, per minute, per second, per season, per time of day.
At Brussels Airport, new technology has stepped in to take over this counting job. Antennas are installed at specific locations in the airport terminal to capture the presence of Bluetooth devices. Each Smartphone and almost all phones are equipped with Bluetooth technology. Bluetooth enables a wireless connection with other mobile phones, car speaker kits or earphones. Therefore they all have an individual, unique identity that can be recognized.
The presence of each Bluetooth device with specific ID-number can be captured in de neighborhood of each antenna. This allows the airport company to automatically measure how much time is needed for an average Bluetooth device to move from one antenna to the next. Place an antenna before the security screening platform, another behind it, and a computer can work out exactly how many seconds are needed for an average Bluetooth device to move through the security area. As approx. 15% of the passengers carry a Bluetooth signature in their mobile phone or Smartphone, this is a statistically reliable source of information to publish exact passenger waiting times.
Important note: a Bluetooth ID only shows the presence of an individual Bluetooth device, but this ID can not be matched with the identity of the owner. All information is strictly anonymous. It would be like counting all the passengers wearing blue shoes: You see that some passengers wear blue shoes, but that doesn't mean you know who they are.
The current trial setup is only one of many possible applications for Bluetooth monitoring. The information can be shown as a set of graphics, spreadsheets or tables. Or in the case of Brussels: as a precise figure on information screens that show the actual exact waiting time at security screening. This information can easily be shown on the airport website, and that is exactly what passengers will find on the Brussels Airport website in the near future. This new information available means that the passengers of Brussels Airport can ease up and not stress their way to and through security, but keep themselves informed before and during the journey about the waiting time.
The idea is not new, but the Danish company BLIP Systems is now specializing in such hi-tech measuring services. Ward Decaluwé, Head of Passenger and Customer Services at Brussels Airport, is thrilled with the new development. "Even if an airport could afford to have someone at each of these locations to measure, all the time, this could never provide us with the fast, transparent and accurate information the BLIP system does. The received information is strictly anonymous. We measure the number of individual Bluetooth devices that pass through the airport building, but we are not able to match these devices with the identity of a passenger. We can only track the number electronic ID numbers of Bluetooth pairing devices, not people, not names. Very soon, this technology will be able to provide our passengers with a faster, more accurate information about waiting times, and a better service".
