So an advisory speed limit for HGVs would have been a more targeted measure, but we can't have that because apparently despite such things being widespread in Europe, it'd be "too confusing" for us.
Advisory speed limits are not revenue generating.
As in every candidate for a Speed Awareness Course netting the plod £40 from the £100 fee.
About time the DMRB was abolished ! Are highways engineers regarded as so thick and stupid they can't be trusted with roads design and their speed limits ?
No, design speed is determined by a list of mathematical formulae that are sound, apart from being extremely conservative.
The problem is engineers don't have the support from yes men project leaders to ever apply engineering judgement and just do whatever the client wants even if it is patently absurd. This is why the A14 Z bend despite being worse in alignment than Ferrybridge hasn't got a speed limit, because no doubt the project manager didn't want one whereas the other one did.
The industry is too top heavy, too many "decision makers" shouldn't even be trusted with the tea run let alone choosing whether or not to go two steps below desirable design minimum.
The other problem is BIM compliance, which is entirely about making paperwork and not good design. This is partly why everything is cut and paste, because BIM compliance requires every file to be numbered, stored, categorised, etc. It's therefore much cheaper to have a single set of design items that have no local variation whatsoever rather than spend time and effort creating new files to comply with BIM requirements.
As ever, the British fetish for administration and bureaucracy along with needless cost cutting to placate Excel spreadsheet wonks rather than providing a workable end product means we spend more time on paperwork and "risk" mitigation than we do in developing a decent scheme.
I'd love to know how other countries, which also use BIM, manage to do a much better job. Maybe it's because they spend the money rather than doing everything for two bob.
