The presentation is a bit weak in that the 30%-50% band is one colour -orange- and that is where much of the variation lies. If you had a better gradient it would probably show more of a trend towards "the closer to town you live, the more likely you are to vote for this".There's a ring around the current CPZ that is about 50% in favour -those places where park and walk is a viable commute policy for outsiders. But with a 7x24 and a pay-for-visitors policy, the scheme was not just trying to stop commuters parking in your street, it was to make you pay whenever you visited anyone else in the city. A lot of the outskirts appear to have noticed this fact. Kingsdown looks like it will be first to go, which will have implications for the neighbours.
Rollout of the RPZ will be really beneficial to anyone driving to school as long as the council doesn't have the audacity to enforce the rules between 8 and 9. It should increase the amount of parking space by the schools, and offer more parents somewhere to park afterwards. I had an excellent discussion with a parent outside Christchurch School last week, someone defending their right to park on the pavement on the "school keep clear" zone. They have to park there because there is nowhere else to park, then they go home over the downs, which must be a least a mile away -but in an area that doesn't suffer from commuter parking. Once the RPZ is rolled out, the right to drive your kid to school won't be limited to those who have driveways or are carrying on to work.
