Supplementary memorandum by Howard Potter
(RP 44A)
This memorandum is intended to provide a brief
supplement to the oral evidence provided to the Transport Select
Committee on 26 January by Howard Potter.
In order to introduce road pricing progressively
I personally recommend the following:
INTER-URBAN
SITUATIONS
Select the critical motorway corridors
eg M1, M6, M4, M62, M11, M3.
Follow the principal of charging
for new capacity.
Either widen on line or provide parallel
motorway. The former to provide both free and tolled lanes; the
latter to be tolled.
Ideally both formulations would provide
a fixed track public transport systempossibly high speed.
URBAN SITUATIONS
With or without comprehensive
congestion charging, apply an equitable, modest, graduated parking
levy on both private and public non residential parking over the
whole area so that the levy captures trips passing through the
central areas. This approach affects most trips and not just the
parking owned by the business sector. The combination of congestion
charging and parking levies would be suitable in London and the
larger metropolitan areas. Parking levies on their own would be
suited to other, larger cities.
Overhaul the regulations for the
workplace parking levy.
Apply the existing legislation for
car park licensing to prevent parking discounts from eroding the
effects of any congestion charge.
Develop innovative means of adding
capacity at critical points in the networkparticularly
near the urban boundaries. Increased capacity might be provided
by introducing "limited facility" under/overpasses designed
for the sole benefit of selected road users eg buses, cycles and
pedestrians without necessarily increasing capacity for general
road traffic.
