Misguides buses are unproven. Wasn't Edinburgh a white elephant? Can anyone cite any good schemes?
The Edinburgh scheme was a short stretch of service 22, which was always intended to be converted to tram tracks.
In fact, the tram tracks are one positive to take from Guided Busways. By maintaining a route (rather than watching viaducts crumble and embankments errode), there is scope for conversion to tram at some stage in the future (a plan in Sheffield 20 years ago was proposed with the "carrot" that the Guided Busways could be converted to tram routes at a later stage.
You can't blame the council here. They are trying to get people out of cars and into public transport. The trouble is that the Government's restrictions (I'm not blaming the coalition, but central Government generally) mean it is very hard for councils to borrow money to pay for infrastructure projects. Whitehall seems scared that local councils will be borrowing beyond their means on "white elephant" schemes, which means the cost of a tram scheme in Leeds/ Portsmouth/ Liverpool (or extensions in Sheffield/ West Midlands/ Nottingham) become prohibitively expensive.
Manchester has got
some of it's tram extensions agreed, after much negotiation, but even then, it's not got everything it wanted.
So, in the circumstances, all the Council can afford is a Guided Busway. Better than nothing, I guess.
Leeds, Bradford and Ipswich all have guided busways which work to one degree or another. Personally I think some of the West Yorkshire sections are too short to be worth bothering with, and that a guided busway would be best on a long single section, like the Cambridgeshire one will be.
Maybe once Cambridgeshire has been running for a few years we'll be able to have a realistic debate about the merits (rather than bleating about "human rights").
