The roads close to the station are where commuter parking is a problem, so why create a solution to a problem that does not exist beyond that area. If commuters start to move further away from the station then that should be the time to look at a CPZ for the affected area.

Pretty much all of the vehicles that park in my street are owned by a growing number of fairly local residents and their visitors, I can’t see how creating a controlled parking zone will change anything for the better; but I can see it making things worse,
Households with off street parking will buy a permit and park in a bay so that they have a clear reserved space for visitors on their drive, as an alternative to the current situation where they have effectively a reserved space in front of their drive.
