Once again a thread in this newsgroup has descended into an irrelevant,
off topic discussion of taxi/private hire/minicab licensing in Cambridgeshire - a subject that some denizens of this realm seem to be inordinately fascinated with. Is there any chance that it can be taken elsewhere - maybe the two main protagonists could perhaps meet up in person, drink a few shandies and then take it outside to the car park? If there is nowhere else to take the discussion, maybe we can collectively vote for a new newsgroup where they can slug it out until they stupify each other rather than the rest of us? |

I don't mean the bits that cross other roads, I'm talking about segregated sections such as the bit in Orchard Park? I'm struggling to see the logic. My understanding is that the guidance system is designed for high-speed running on large-radius curves (i.e. on an old railway alignment), and does not cope safely with curves below a certain radius. In order to fit around the Orchard Park devlopment, that section of busway has a bend which is too tight for guidance. It doesn't matter, as that section is low-speed, and only a short distance between the junction with the main busway and the point at which the busway ends. At both of those points the driver has to take over the steering anyway, so doing so between them is no great matter. The only other significant unguided segregated section I am aware of is the new piece between Milton Road and Cambridge North Station. This doesn't have sharp bends, but again is short and low-speed. I would guess that cost was the deciding factor there. --- This email has been checked for viruses by AVG. http://www.avg.com |

At both of those points the driver has to take over the steering anyway, so doing so between them is no great matter. The exception on the Orchard Park section is the stops and a short eastbound section near Histon Road. They were built with true guideway sections. All newer guidance is by steel strips on flat road surfaces. The only other significant unguided segregated section I am aware of is the new piece between Milton Road and Cambridge North Station. This doesn't have sharp bends, but again is short and low-speed. I would guess that cost was the deciding factor there. This is probably true but the unguided section at Orchard Park probably and the approach section to Cambridge North station definitely are unguided on cost grounds. The guideway track sections were cast at a concrete factory set up specially for the purpose at (I think) Longstanton. Once the sections were made it was demolished and the site is now a park and ride car park. So the cost of making new guideway sections would be prohibitive and that's before you talk about getting the special laying machine back on site. I'm not even sure what happened to that. None of the Cambridgeshire kit was used for the Luton busway which has shorter track sections which can be laid by mobile crane. They probably don't have a track section casting capability at Luton any more either. -- Colin Rosenstiel |

Technology moves on, as you of all people should know. At least out-of-town taxis now only risk getting a ticket (assuming they aren't allowed in that particular bus lane), rather than a smashed sump. Smashed sumps in general happened to chancers not out-of-town taxis. The layouts have changed, with many of the cycle bypass lanes removed. Does that mean cycles are not permitted or are they thrown into the chicane with the buses? No change to cycle access rules. But they share with other vehicles at some of the bus gates now. If you cycled in Cambridge you would have noticed a year or more ago. I'll look more carefully next time I walk. It's going past on a daily basis that showed me the changes as they happened. I also noticed that the New Square bollards stopped working long before they were officially replaced. Obviously none of us locals made that public, not wanting any more chancers going through illicitly. -- Colin Rosenstiel |
