To continue on the topic of pedestrian modeling: recently, I heard the news that the new terminal being built in the St. Petersburg airport will be tested using a free labor force, or in other words, volunteers. Actually, the volunteers will test the terminal’s operations and on-ground facilities by acting like passengers. It was interesting to find that the London Heathrow and Dubai airports are using this practice right now too. Here in St. Pete, they gathered more than 5,000 volunteers, to come to the terminal and walk around, jostle to check-in desks, race up the down-moving escalators, get bored in queues to passport controls, etc. I suspect that the volunteers will be watched by engineers, who will be counting the number of injuries per minute. That’s how airport authorities are going to see if everything is OK with the terminal.
