Yes, we have done plenty of work on that, which we can send to the Committee. In particular, we produced a report a few years ago on public transport-oriented development, which showed that you could get much higher densities in urban areas that were already served by an intensive public transport network. In turn, that mutually reinforced and made sustainable public transport improvements within that area. There is certainly more on that that we could send to the Committee, which we would be very happy to do.
In addition to Carolyn’s point, I also want to say something very quickly on the rural aspect as well. Cornwall in particular is a possible trailblazer on rural devolution, in terms of what it has been able to do to integrate its transport network—that is in trains, ticketing and single points of information. It has also done some great work in terms of setting housing policies and on retrofitting rural housing stock. It does seem to be an exciting model that others could look at.
