Welcome
to this 28th edition of the Transportation Energy Data
Book. Over two-thirds of these editions have been produced
by Stacy Davis. DOE is grateful for her dedication and
the skill she has brought to this effort.
We
would like to bring to your attention some of the data
that is new in this edition: |
| 1. |
Figure 2.2: Light Rail Transit Energy Intensity. These data show the large variation in light
rail energy intensity across metropolitan areas in the U.S. |
| 2. |
Table 3.10: Car and Light Truck Survivability Rates and Lifetime Miles. A new source for
these data is now being used. The light truck lifetime miles is 174,954, which is 27,817
more miles than for cars. |
| 3. |
Table Table 5.10: Effect of Terrain on Class 8 Truck Fuel Economy. These data show the affect
of slope and of single wide tires on fuel economy.3.4 shows the number of vehicles per 1000 people in
different regions of the world for 1996 and 2006. The
values for China grew from 9.3 to 26.6 in this ten year
period. |
| 4. |
Table 8.11: Share of Vehicles by Annual Miles of Travel and Vehicle Age. These data show
the annual travel for vehicles as a function of age. For example, only 3% of new vehicles
travel less than 1,000 miles per year, whereas, 7% of 10-year old vehicles and 47% of
vehicles over 20 years old travel less than 1,000 miles per year.. |

Table 10.11: Average Price of a New Car, 1906-2007. A number of sources were used to
develop these estimates of new car prices back to 1906. These data show that in 2007
constant dollars, a new car in 1906 had a cost that was $13,106 greater than the cost of
a new car in 2007. The real cost of a 2007 new car was $453 less than a new car in 1986. |
| 6. |
Table 11.7: Transportation Greenhouse Gas Emissions by Mode, 1990 and 2007. Heavy
trucks had the biggest percent increases in CO2 between 1990 and 2007. |
| 7. |
Table 11.11: Carbon Dioxide Emissions from a Gallon of Fuel. |
| I
hope you find value in this data book. We welcome suggestions on
how to improve it. |
