Dear Paul,

It is an interesting paper, and it is good see some creativity being applied
to different charging approaches.

I wonder, though, if ultimately the vehicle quota system is dropped and a
distance-based scheme is the sole mechanism, then there will be significant
purchases of second vehicles.  Families could get around a 25,000 km quota by
simply purchasing many vehicles.  

Further, if a person has a 25,000 km quota, then there may be a psychological
push to fully use up your credits, even when there may not be an actual demand
for the distance.  Or persons may end up leasing out the vehicles which have
spare kilometres.  Whenever there are credit systems based on a total amount,
then the system works to ensure persons will fully use the available credits. 
By contrast, marginal charges, such as the ERP, are effective in directly
charging for each km at the point of use, and thus directly provide an
incentive to curb usage.

The paper begins with the point that the current combination of vehicle quotas
and road pricing has "major drawbacks".  But it is not quite clear what those
major drawbacks are.  The only point made in this regard is that the large
upfront vehicle costs dwarf the marginal ERP charges, and thus psychologically
create a situation where usage seems inexpensive.  If this is the only
problem, it seems like you could just change the balance (e.g., raise the ERP
charges).  This would seem far simpler and more effective than introducing
another new scheme altogether.

I do not know the situation in Singapore well, but it seems somewhat implicit
in the paper that the vehicle quota system is under political pressure.  Are
new schemes being proposed because ultimately consumer pressure will mean a
lifting of the vehicle quota system?

Thanks for sharing the paper.

Best,

I have written something related to this topic. It has a Singapore-focus
but is probably of wider interest too. It is a work-in-progress, so
comments criticisms are welcome.

"A vehicle quota integrated with road usage pricing: a mechanism to ease
the phase-out of high fixed vehicle taxes in Singapore"  by Dr Paul A.
Barter

Abstract
This expository paper suggests a way to integrate a vehicle quota with
usage based charging, including road pricing. It thereby challenges
assumptions that ownership control requires high fixed vehicle costs. It
focuses on Singapore, which has high purchase taxes and a Vehicle Quota
System. These are effective but result in certain problems. The
authorities are gradually relaxing ownership control and increasing
reliance on usage charges. Mechanisms are proposed to variabilise fixed
taxes, including the vehicle permit price, in ways that are compatible
with the vehicle quota. This could make the shift to usage-based
charging more efficient, complete and flexible.
