Yes - that's exactly what I'm saying. We've got passengers accepting paying £4.50 to get to the Airport and you think that £2.50 is too much for journeys like Balerno/ Bonnyrigg into central Edinburgh?
If Lothian ever move away from the current flat fare on "City" services (which, as we know, includes Balerno/ Penicuik/ Gorebridge/ Wallyford/ Seaton Sands etc) then the city bypass seems a fairly logical divide to have for the increased fares.
Of course it won't be popular (which is why I'd suggest it goes hand in hand with a slight reduction for fares wholly inside the bypass, so the majority of passengers benefit), but people in most other big cities would be paying more than £2.50 for journeys like Penicuik - Edinburgh.
The alternative (if you are moving away from the current flat fares on all maroon services) would be to have some big jumps for only going one extra stop and bringing confusion to a passenger base used to simple fares - it's simple with the bypass - there's no complications over what is/isn't a fare stage - often there's such a long unappealing walk from one side of the A720 to the other that passengers would be unlikely to try gaming the system.
What's your alternative?
I already gave mine. Either have a £1.70 city / £2.50 country fare on LCB after Ratho/Balerno, you'd up the fee, or have one flat rate for the entire network (ECB, LB, LCB) of £1.80 with day tickets costing £5 which would be useful for those getting more than 2 buses and those tickets can be used on ANY service within the network (exc airport or other special services).
The reduction for city you suggest is all very well for those living in the city but for those who live just at the other side of the A720 who get charged £1.70 right now would not be pleased if it were to suddenly rocket up by 80p (to and from work mon - fri is an extra £8 per week for no improvement in their service). It is why I think in the end of it were £1.80 flat rate with £5 day ticket, would be more palatable. I would assume if you upped the price by 80p, more would want to drive in, especially in the first few weeks, and forego the bus. Then there is the ridacard holders. Would they get a rebate if they only used city buses (for those who pay monthly/yearly)? How would that be worked out?
Another good reason for making it £1.80 flat over the entire network is you could easily roll out the ridacard on ALL services, as there would not be 2, 3 or 4 tiers.It would ALSO give First a nod as LB would be cheaper and not by a small amount either so more pax would be heading to LB.
As I said before, there is no good reason to charge £3.80 to go from City to St Johns H when I can do a journey on the 44 or 26 end to end for £1.70 which is longer in terms of miles travelled and time on board, but to up the fares for those on existing routes (44, 26, 33, 3, etc..) who live not far from the other side of the A720 would not be welcomed for no improvement to their services.
