10/26 Schwartzenegger grants DMV additional stickers, allowing up to
10K hybrid vehicles to hog up the carpool lane.
\_ Hogging? Isn't the point of the CP lane to reduce gas consumption?
It seems the right place for a vehicle with lower consumption. I
don't own one, I drive a gas hog V8, but I don't have a problem
with single passenger hybrids in the CP lane.
\_ 2-3 people in a car doubles to triples the fuel efficiency of
the car... hybrid w/ one person (which is the only reason to
have the sticket) may not compete with that (especially if it's
2-3 people in a non-gas-guzzler)
\_ I thought it was supposed to reduce congestion. Besides hybrids
are most efficient in stop and go, so the space should be made
available to non-hybrid cars that need to keep moving.
\_ Agree, it's for congestion.
\_ The point of HOV lanes is to encourage carpooling. More
carpooling improves both congestion and per capita fuel
expenditure, but HOV lanes themselves increase congestion
by reducing the number of lanes available overall (since
less than 1/4 of cars qualify, so more than 3/4 of all cars
must use only 3 of 4 lanes). I think Varaiya did some
research into this recently.
\_ US transportation policy is completely inane. We should
double or triple the number of highway lanes.
This would save billions in man hours wasted sitting in traffic,
reduce emmission, save gas, and generally result in a greatly
improved quality of life.

\_ It improves fuel expenditure, but the point of it
is/was to relieve congestion via carpooling. The
mileage your vehicle gets was never part of the
equation.
\_ Carpool lanes carry much more traffic than other
lanes, as long as you don't do stupid things like
allow hybrids to use them. (But mainly, carpool
lanes are a scam to get semi-eco-conscious taxpayers
to approve more road construction; carpool lane
constraints are always loosened after the bill/bond
passes). -tom
\_ Varaiya's research: link:csua.org/u/hbd
Conclusions include an increase in overall congestion
and no significant increase in throughput of people
(which is what I assume you mean by "more traffic").
I find some of the arguments made in the paper to
be unconvincing (in particular, the paper does not
address the issue of reduced demand outside HOV hours)
but I'm inclined to believe that the conclusions are
more or less correct. I'd be interested to see data
to the contrary if you have any. -gm

\_ The issue you mention is a pretty significant one;
the primary finding of the paper is that traffic
moves faster from 7-9 PM than it does from 4-7 PM,
and there's an implicit assumption that the
traffic would move at the 7-9 PM speed if the
HOV lane didn't exist. I think that's fairly
ridiculous. -tom
\_ A couple years ago CalTrans said more people passed
thru the carpool lanes on the left and right of the
west-bound Bay Bridge approach during commute hours
every day than that on all the other 14 toll lanes
combined.
\_ I guess you could argue the carpool lane rules reward good
behavior, whether it is carpooling or driving a fuel efficient
vehicle.
\_ Buying a new hybrid car in order to use the carpool lane is
wasteful. And why reward hybrids and not any car getting
above some mpg value? This is idiotic and so are you.
\_ I can think of some reasons, and so can you if you bother
to think about it, but I agree that the reasons are
mostly stupid. |
