The Virginia General Assembly today passed the extension allowing single occupancy hybrids to continue to use the HOV lanes through June 30, 2012.

Your data is for a Diesel engine without the Diesel particulate filter.




I know exactly what they are and DC metro buses do NOT have them. For a system that is already broke, $6,000 per vehicle was too much to fund.



From the Metro Website:

quote:
What is Metro doing to help regional air quality?

Our entire 1,500 Metrobus fleet is eco-friendly: 439 buses run on Compressed Natural Gas (CNG), 117 buses run on advanced technology diesel, and 50 buses are diesel/electric hybrid. All remaining buses in the fleet have completed the Clean Fleet project, which includes the use of ultra low sulfur diesel fuel in conjunction with exhaust treatment devices to lower emissions.


Having seen the engine compartments of most of the busses, I can tell you that you're WRONG.


Furthermore, we're talking about the HOV lanes from Dumfries on up to the Pentagon. Most of that is outside of WMATA's jurisdiction... I fail to see what Metro busses have to do with anything. The PRTC busses that run up and down the HOV lanes are equal to, if not NEWER and BETTER equipped than the Metro busses.

One bus is better than thirty cars.

However, Cars carrying three or four people are better than cars carrying one.

Times to beat:
Horner Rd to/from Pentagon: 12 mins Without Slugs - 17 mins With slugs
Dale City exit to/from 3rd St Tunnel, D.C. 18 mins (No slugs - Holiday)

The California Air Resources Board has concluded that diesel soot is responsible for 70% of the state's risk of cancer from airborne toxics. In the population as a whole, studies have shown a 26% increase in mortality in people living in soot-polluted cities.

Actually, it is a FAR bigger help to the "system" than slugging - unless you narrowly define the system as slugging.

If slugging were eliminated while allowing hybrids to use the express lanes during peak commuting hours:
- slugs would probably have to use buses
- there would be less congestion (HOV-33 is better than HOV-3)
- the air would be cleaner
- fuel consumption would lower
- gas prices would be lower
- the economy would improve (just like cash for clunkers, but with no taxpayer subsidy)

THAT'S why the grandfathered expemption always passes with a HUGE majority - it just makes sense!



Based on what data?

Sounds like another misinformed tree-hugger.

Hybrids contribute emissions to the atmosphere as well. While hybrids emit on average 25%-30% less carbon dioxide, they do so with one person on the HOV. A slug vehicle with three people will emit less carbon dioxide than the three hybrids it replaces. Until we have hydrogen vehicles, you are still putting carbon into the atmosphere.

The congestion is a function of too many hybrids with only ONE person in them.

Buses, particularly diesel powered one are FAR worse for the atmosphere. Emissions from diesel engines are many times more damaging to the environment than gasoline emissions. Diesel carbon content is 2778 grams per gallon compared to 2421 for gasoline, but the real damage comes from the particulate matter (soot), emitted when diesel is burned. Particulate matter emitted from diesel engines is double that of gasoline powered engines 60 nano versus 30 nano.

Gas prices would not be lower...sorry, but the consumption is northern Va is not going to have an impact on the global oil situation.

The air would NOT be cleaner. Sure congestion would be less on the HOV, but you would be transferring the congestion to the suburbs as people try to reach mass transportation. With gridlock on the two lane roads in the suburbs, emissions would go UP.

It is one thing to be concerned about the environment (I am), but reality and the facts should be considered as well. Get the hybrids off the HOV and you will decrease congestion and emissions.

Delegate Thomas "Tag" Greason (Loudon County) (introduced HB 1432): deltgreason@house.virginia.gov

Delegate Kenneth Plum (Reston) (introduced HB 1754): delkplum@house.virginia.gov

Delegate Eileen Filler-Corn (Springfield):delefiller-corn@house.virginia.gov

I will be calling to ask them to vote to extend the exemption!

Well unlike most federal employees I have to pay for mass transit. Since I am the one paying I pick the cheapest route. When I drive I pick up three others.

Yes mass transit is better than car pooling. Now with that said you would also have to agree that a single riding Hybrids cause more traffic not less. So I am glad to see you would like the Hybrid exemption removed as well. Thank you for your support on this effort.
