"I don’t think “incompetence” is a sufficient word for perpetuating mistakes on this scale!"
It's not incompetence or even fear. It's systemic bias, political calculation and awareness of vested interests.
Council officers (and presumably consultants) know full well that the *only* meaningful challenges to TROs can be on three grounds: loss of or changes to loading bays; prohibition of vehicles and/or one way carriage restrictions; and restrictions on bus services. Objections on any of these bases, if not withdrawn, may lead to a "hearing" and Scottish government involvement. Thus causing potentially very large delays to the project.
So the designs are very obviously attempting to head off challenges and objections on these grounds by attempting to preserve as many loading bays, bus stops, and general traffic lanes as possible.
This systemic bias in favour of parking/loading and motor bus services is built into the planning legislation. Ultimately meaningful change can only come about if either of the following happen:
- Planning rules around TROs are changed by act of parliament (good idea but don't hold your breath).
- Council shows political determination to follow transport policies, enact real change and take the delays (and possible cost overruns) on the chin.
- Council provides reasonable alternative facilities to appease objectors nearby (e.g. on side streets) but then stokes wrath of residents' "I want to park outside by house" lobby.
Given that the Council has only a limited amount of time before the powers in the tram act expire, you can see how they might choose to mitigate risk to their project by getting the objector appeasement in first. They're taking the path of least resistance, literally. Objections by cyclists, pedestrians, literally don't count for much legally speaking, so can be largely ignored. That's the harsh reality, regardless of what council transport policies may or may not aspire to.
Of course, if elected councillors were faced with huge media outcry, civil disobedience, legal challenges, etc. the political will might change direction. Does anyone really think that scenario is possible?
