The record for previous initiatives of this kind is not very encouraging.
There were similar proposals many years ago for a park and ride at Iver on
the GWML which is practically adjacent to the M25 and has lots of unused
land adjacent to the station. I believe the DfT objected because it would
require a new junction on the M25, and it would also generate more traffic
on nearby motorways rather than relieving them.

Yet Haddenham & Thame Parkway went ahead, without objections and with no
improvement to the local road system whatever - access only being via the
back road that parallels the A418 between Aylesbury and Thame! As the car
park at that station now extends almost to the A418 at the northern end, it
is surprising that access there hasn't been improved, given the number of
cars that thunder along the back road. Many of theses are local but there
are also many users who drive to H&T Pkwy from the M40.

On that basis, even a DGC Parkway without a direct M25 connection, serving
the local area, the A40 and A418 would be of benefit and would relieve the
pressure on the centre of Gerrards Cross and the area to the west of
Chorleywood.
