So maybe they feel that it is cheaper to maintain those counters and GTMs..
And considering that the no. of GTMs will have to cater to peak hour traffic, they will need to maintain a number of GTMs that is probably idling 90% of the time and consuming electricity.. talk about being environmentally friendly.. (someone say they're "green in their advertisements?).
If GIRO is encouraged and, say, 95% of commuters is on GIRO plan, wouldn't it mean less money spend on operating these GTMs? And since there'll be a number of new MRT stations in the pipeline, it will incur less expenses by buying less GTMs.. Are these not obvious benefits to the company?
And naturally, GIRO is much "greener" than those GTMs that sits there idling and consuming electricity and generating heat 24/7 in some air-conditioned MRT stations. It's not a lot, but it counts, doesn't it?
