The answer to the bus fare evasion problem is to do what many American cities do and install ticket vending machines /or metrocard recharge machines inside the bus itself similar to what is seen on our trains. Furthermore, having roving security guards inspect tickets and hand out on the spot fines on random bus services will also make huge inroads into our rampant bus fare evasion.
What a laugh that has been done and is still probably being done and it has done not one iota of a thing. There are not enough people working on the trains for starters to check every single ticket or rider. And they no sooner have a blitz on one line and move on and the fare evading starts again. Even things put in to stop fare evading do not work, entrance gates at Nourlunga Centre installed there at God only knows what cost and they leave a access gate wide open with no one monitoring it, waste of time and expense putting in the access gates worked by you ticket in the first place.
Pity it could not all be made free travel in the whole Metro area think of the money it would actually save, you would not need tickets printed to start with, you would not need Metrocards made, you would not need any of the validators etc and their on going maintenance, you could remove ticket selling machines and their maintenance. and there are probably a few other things as well.
Also you would not have to worry about the expense of chasing fare evaders that do not pay fines plus a whole host of other things.
But that would never be done though, but I cannot really see the sense in anyone travelling without a ticket as the actual ticket is the cheapest option if you stop and think about it. If caught without a valid ticket the fine is in 3 figures before you get to the cents. Cheaper to purchase the ticket.
