Cities With The Worst Pain At The Pump By Matt Woolsey, Forbes.com
May 13th, 2008
Gas prices in Texas are among the cheapest nationwide, but that doesn't mean commuting by car there is light on the wallet.
Indeed, though the cost of gasoline does matter, other factors, including distance, congestion, carpooling rates and use of public transit also play important roles.
Those living in Houston and its outlying suburbs know this. By these measures, the metro ranks as the nation's ninth most affected by rising gas prices, even though the average driver pays a relatively cheap $3.49 a gallon (as of May 1). Why? Ninety-five percent of residents drive a car to work. What's more, sprawl and congestion collude to increase driving times, and clogged highways greatly cut fuel efficiency.
But that's not nearly as bad as California's "Inland Empire" of Riverside and San Bernadino, Atlanta, Washington, D.C., Chicago or Miami, where prices, traffic and commuting patterns really pack a wallop when it comes to time to fill up. Others feeling the pinch: Birmingham, Ala., Los Angeles, Raleigh, N.C. and Sacramento, Calif.
Behind The Numbers To arrive at this list, Forbes.com took the country's 50 largest metro areas and looked at congestion, fuel costs, use of mass transit and carpools and commuting distances to determine which were the most affected by rising gasoline prices and calculate how much commuters pay each day to get to and from work. All fuel costs reflect May 1 prices.
Using the Environmental Protection Agency's fuel-efficiency curve, we first adjusted gas prices for traffic by calculating what portion of the average commute is driven at maximum fuel efficiency.
"When we're going between 50 and 60 miles an hour, we're burning 23 miles per gallon, but as you drop down to, say, 20 miles per hour, that number is more like 16 miles per gallon," says David Schrank, a research engineer at the Texas Transportation Institute (TTI). "As you get more and more stop-and-go--with the emphasis on the stop--you start … going nowhere and burning gas." .....(more)
