The system connects the 2,000 stops and 750 buses that run through the city.
This operation can also be done via internet. If you carry the laptop on top, you have a pass but if you do it from home I doubt that you will have time to turn off the equipment and go down the stairs.
My curiosity called me to send the message. Time (space) and stop code. I automatically received a message with all the lines that passed through my stop and the time it would take to arrive. A really useful service.
The classic of lighting a cigarette for the bus to arrive is over.
