I originally posted this in the Spokes Autumn Public Meeting discussion but, as Chris pointed out, it's worth starting a thread spefically on this topic while we wait for CEC/Marshall Poulton to confirm consultation details in the Spring.
Is Princes St like a Talisman?
I think that's the key question here. In an ideal world it could be great to have a pedestrianised Princes Street and George Street, for that matter, but I don't see Princes Street as something to die in a ditch for, so long as a dedicated E-W cycleway can be secured.
Realistically, the geography of central Edinburgh means that there needs to be through routes for:
1) buses
2) cycles
3) cars etc
And that's not to mention delivery lorries, bin lorries etc.
Cars etc. are on Queen Street, and that seems to work. Buses wouldn't be great here as it's not near the shops and it appears that the average pedestrian is not prepared to walk two blocks to get to a shop. And that's without considering those who are unable to walk that far. The down side of all the cars is it's not the nicest street to cycle along, but that should not be a problem if we have better cycling provision on either George or Princes Street, and we've always got Heriot Row as a quieter alternative down the hill.
That leaves Princes Street or George Street for buses. Personally, I think the width of George Street and its buildings and junctions mean that it is not a good street for buses. It's not been a geat experience walking in George Street these past few months while the bus diversion has been in effect. Also, interchange of bus passengers with the tram will be greatly facilitated by having them on the same street (ie Princes Street). So that looks like Princes Street for buses.
Which leaves cycles on George Street. Ideally, this should be a pedestrianised public space, with all the quality of life benefits that come with that, with demarcated cycle lane. However, I can see that the issue with that is parking spaces. Perhaps this could be overcome by pushing Park & Ride and the tram, or provision elsewhere of more parking spaces (the New St James Centre perhaps?). Or perhaps a compromise could be reached in pedestrianising some, but not all of the blocks of George Street, with the option of extended the ped zone either temporarily or permanently as required.
