Between 1950 and 2008 more cars were added to our roads virtually every year as the total fleet expanded steadily from 49 million to 250 million vehicles. In 2009, however, 14 million cars were scrapped while only 10 million cars were sold, shrinking the fleet by 4 million vehicles, or nearly 2 percent. With record numbers of cars set to reach retirement age between now and 2020, the fleet could shrink by some 10 percent, dropping from the all-time high of 250 million in 2008 to 225 million in 2020.

The United States, with 246 million motor vehicles and 209 million licensed drivers, is facing market saturation. With 5 vehicles for every 4 drivers, the 4-million-vehicle contraction in the U.S. fleet in 2009 does not come as a great surprise. In a largely rural society, more cars provided mobility, but in a society that is now over 80 percent urban, more cars provide immobility.

Highway barriers erected along roadways can be perceived as massive monuments to the future and were intended to block the sound and sight of traffic for the adjacent neighborhoods. They may do a bit more in terms of air borne pollution. In a study by NOAA and the US Environmental Protection Agency, researchers released harmless “tracers” to measure the potential movement of pollutants such as carbon monoxide and heavy metals, and volatile organic compounds such as benzene. The results showed a significant reduction for those neighborhoods in pollutants as a result of the barriers.

Highway barriers were originally designed to help block highway noise as well as to improve the view for nearby residents. At first the barriers were somewhat ugly but many now have vines and other vegetation softening the aesthetic effects. (more…)

The number of cars on U.S. roads dropped by 4 million in 2009, the only large decline in the nation’s car fleet since the government began keeping records in 1960. While consumers bought 10 million cars during the year, another 14 million vehicles were scrapped, dropping the total to 246 million vehicles, despite the government’s “cash for clunkers” program that gave individuals as much as $4,500 to exchange older cars for more fuel-efficient models.

Analysts cited numerous factors for the decline, including high gasoline prices, improved public transportation, and the popularity of online social networking, which for many teens has replaced the automobile as a way to socialize. In a report analyzing the decline, the Earth Policy Institute says the decrease is not merely a temporary phenomenon caused by the recession. (more…)

Some heavyweights who know a thing or two about transportation are having a pointed online debate about whether or not electric vehicles should receive support from the federal government.

Terry Tamminen, who was Secretary of the California Environmental Protection Agency under Republican Governor Arnold Schwarzenegger, threw down the gauntlet last month in an editorial in which he stated that “it’s time to dump the battery-powered car in the same policy landfill as corn-based ethanol.”

Ford Motor Company has developed an intelligent charging system that previews how its production vehicles will interact with the grid. The unnamed system enables all-electric and plug-in hybrid vehicle owners to restrict charging to when electricity prices fall below a certain threshold, or even “when the grid is using only renewable energy such as wind or solar power,” according to Ford.

Being able to drive “emissions free” could be a huge selling point for the upscale and eco-minded early adopters who will be buying EVs and plug-in hybrids during the next few years. There’s a natural synergy for customers to put solar on their homes and buy hybrids/EVs, who can then drive free of fossil fuel guilt.

By all accounts the cash for clunkers incentive program has exceeded all expectations in both volume of sales, as well as answering skeptics by getting fuel inefficient vehicles off the road.

The new vehicles being purchased average nearly 10 mpg higher, saving nearly 4 million barrels of oil per year and eliminating the production of tons of greenhouse gases.

More importantly, the program and its surrounding attention seems to have driven consumers towards hybrids and fuel efficient vehicles even more than a 50 cent spike in the price of gasoline. According to Brian Benstock, the VP and GM of Paragon Honda and Acura, the program is also introducing new customers to imports. Benstock said the program has reversed the ratio of domestic/import trade-ins at his dealership. Previously about 70 percent of his customers were trading one import (mostly Hondas) for another. Now it’s the opposite: 70 percent of people walking in the door are swapping American made autos for Hondas.

The cash for clunkers program is already proving too good to be true. The $1 billion in funds allocated for the program is almost gone after less than a week, and now congress is scrambling to get an additional $2 billion to extend the program.

With sales up at Ford and at dealerships, the program can be viewed as an unabashed success for the auto industry. And the environment is also winning, as the vehicles being purchased are estimated to be 69 percent more fuel efficient than the vehicles being dumped, according to the website CashForClunkersInformation.org.

Detroit car makers would increase profits by $3 billion annually and significantly boost sales if they improve the fuel economy of their vehicles by 30 percent to 50 percent, according to a new study.

Conducted by the University of Michigan’s Transportation Research Institute, the study found that a major reason for the precipitous decline of Detroit’s sales and profits in recent years was the refusal of the Big Three automakers to recognize the importance of fuel economy to consumers. That failure meant the steady loss of market share to foreign car companies whose vehicles got significantly better mileage, the study said. Had the Big Three paid attention to their own market research showing the importance of fuel economy, “they would not be in Chapter 11 today,” said a co-author of the study.
