My system constantly adapts to the traffic of the various metros, because each metro, thanks to a CBTC system, knows where the metro is in front of it and thus adapts its driving.
25% of travelers go to a destination of the same color as their departure station and can take any metro that stops, so this 25% of travelers regulate the overcrowding of passengers in the subways.
In addition, multi-colored connecting stations also make it possible to regulate the excess number of passengers.
Indeed, a traveler going or coming to a multicolored station can take the least loaded metro of the 3 that stop for their destination.
