I wonder if in somewhere like Japan they might have closed the road entirely, rather than trying to maintain it as a through route. Not sure about 12 weeks though - it’s a total transformation of the urban realm.Until someone complains to TFGM that they waited 2 hours on deansgate for a 67/100 and then they will insist they use normal route.
Not disagreeing with your statement but it’s the length of time it’s estimated to take and the chaos In the mean time. If this was in china or Japan it would have been undertaken and completed in a matter of weeks with little impact to everyone not 12 months.
Wait till the Christmas markets start then it will be chaos!
I have some sympathy with the planners- traffic modelling is less scientific than it sounds. The crucial thing is to be adaptable when things don’t work out as you expected. Hopefully they’re on the case there, but it must be difficult and there is a danger of making things worse through unintended consequences.
I do feel that there seems to be a lack of coordination, however. If there are big events in the central area, are measures such as closing car parks and increasing park and ride provision ever really considered?
