I think that Walter makes a valid point: it is not so much car ownership
which is the problem but rather the use of those cars which creates all
sorts of negative exernalities. Furthermore, why punish an urban dweller
for owning a small car (for the occassional shopping at IKEA) and reward
the suburbanite for owning an SUV? In general, the trip from home to
work often has a reasonable chance of being well-served by transit, even
for someone living in the suburbs - the problem is that few people make
such "simple" trips anymore. There are the kids to drop off, the
groceries to buy, going out to lunch, etc. In any case, it is no longer
certain that central-cities are the primary employment "centers" in a
region anymore. Mass transit can also serve disjoint development
clusters reasonably well, but as activities become more and more
dispersed geographically personal transportation options become the only
viable options. Throw in the vast quanities of free parking at shopping
malls, and the car looks like a very attractive option indeed.
Parking pricing policy is a rather blunt tool to use when trying to
internalize the external costs of car usage, but it may be more
politically palatable than congestion pricing. Italy for example has a
number of quite simple parking policies which I think go some way
towards 'rationalizing' car usage while not overly discriminating
against urban car owners:
Every car registered in Italy receives a little paper hand-clock to
place on the wind-screen. There are many places where there is free
parking /for up to one hour/ - the driver is responsible for setting his
clock properly to indicate when their "time is up" (although it was
never clear to me if this was the time when we arrived or when we had to
leave). Get caught overstaying your time and it is a stiff fine
(something like 100 Euros)!
Other places have advanced-pay parking rates which increase with the
parking duration: 1st hour=1 euro, 2nd hour=2 euro (ie 1+2=3 euros total
for two hours parking), 3rd hour=3 euro (ie 3 hours=1+2+3=6 euros), etc.
This payment method recognizes that there is a need for parking spaces
while also discouraging long-term parking. Often this type of
arrangement is combined with resident-only parking - residents can leave
their cars in the parking area indefinitely without paying anything.
As long as congested urban areas are "competing with" new growth areas
which have essentially free and unlimited parking, the car will remain
an attractive option.
Best regards,
