Malacanang is mulling privatizing the ticketing services of MRT and the LRTs.
If all three lines were unified under a single ticket system, it would vastly improve mobility in the city. (That plus closing the MRT-LRT1 loop.) It may cost an extra P2.50 per ticket but if the ticket company is creative, the cost of the actual ticket can be passed on to advertisers. Many other cities use advertising on the tickets. It might also be a relief to be rid of politician's mugs in our wallets.
Cities and municipalities serviced by the MRT/LRT should also respond with policies that encourage the use of mass transit. They can, for instance, allow companies to provide employees with monthly MRT/LRT passes as pre-tax benefits. Labor unions should ask for this benefit.
Cellphone companies can get into the act by allowing re-loading of transit passes via text, etc. Malls along the mass transit lines can also join by providing discounts to monthly pass holders.
A more ambitious program would unify all transport ticketing -or at least MRT/LRT, bus and FX taxis -under one fare system that allows no-charge or discounted transfers. This is not so far fetched. If the OBR succeeds, implenting a single bus-ticketing system won't be impossible. And if the LTO gets its act together, it can apply a similar system on the FX/shared taxis -and from there, it'll be a short throw to uniting all three fare systems.
Aiming for such a program may also provide the impetus/political will to abolish the boundary system.
The single metrowide fare system might provide beneficial (unintended) consequences by necessitating a rational interconnection between the various modes of transport.
