Some more background that may help those who are not convinced by the guided bus hype.The text below was provided by our group CAST.IRON - the people who opposed the Cambridge busway - to the local media in response to a recent question about busways:
We still do not believe there is any tangible evidence of the ^success^ of the Cambridgeshire Guided Busway scheme in terms of it being a proven, better alternative than coordinated train and bus services appropriate to any given area. The constant stream of passenger number statistics doesn^t tell us anything because it doesn^t analyse journeys not made on the guided sections. The statistics cover Peterborough to Trumpington but between Cambridge station and Milton road, and north of St Ives, the buses are the same as any other.
In short, we don^t accept that the guideway is what is driving the passenger numbers; and we believe much wider benefits would have come with reinstatement of the railway.
The problem with the Cambridgeshire scheme is that it obliterated a viable rail route on an alignment that makes geographical sense as a railway, not as a bus route; for buses to derive benefits from the segregation of the guideway they have to travel well over a mile along congested streets in the wrong direction. Meanwhile a route that could be part of the local, regional, national and international rail network is lost.
The minimum journey time from Cambridge station to St Ives on the busway is 42 minutes subject to congestion in Cambridge. The same route by railway would have been less than 20 minutes.
CAST.IRON does not have a particular view on the viability of guided busways elsewhere although we did do some detailed work on the construction side of things and showed that the volume and mass of material required (for the guideways) is many times greater than for a railway with a much lower potential for maximum passengers carried. This is one of the reasons why there have been such serious construction and maintenance problems on the Cambridgeshire scheme.
We believe guided busways generally offer poor value for money compared with integrated rail and bus schemes. Unfortunately for Cambridgeshire, the only money on the table was for an exclusive busway.

Note that last comment about money - there was a lot of government ringfencing going on to get what they wanted - a substantial busway
