Any new transportation scheme that is going to supersede a substantial
proportion of road traffic must provide:
At least as good access to all types of location such as
homes, shops, businesses and leisure facilities.
Carriage both for people and most goods.
Faster and more reliable movement from door to door.
Accessible to all, regardless of age, driving skills, capital
resources, state of health or inebriation.
Major improvements in energy efficiency and a major reduction in
total pollution.
Near complete elimination of pollution in the vicinity of the
users.
Cheaper for users.
Profitable for operators and manufacturers.
Safer and quieter for users and non-users.
The capacity to evolve; any scheme capable of making a
significant difference is likely to take many decades to introduce,
during which it will have to operate in parallel with existing modes
of transport. It must be able to adapt to problems that will arise
and technological developments that might occur.
