個人理財網(wǎng)站W(wǎng)alletHub不久前做了一項特殊研究，評估對象是人口排名前100位的美國城市（不計大都市周邊地區(qū)），主要標準包括獲得車牌及維護的成本、交通狀況與基礎設施、安全、買車與車輛維護的渠道等四個方面。

以上四大衡量標準又可細分為總共29個小標準，比如車輛失竊數(shù)量和汽油成本，每個亞標準都有一個權重值。每項標準下城市都會得到從零到100范圍內的評分，100分為最佳。根據(jù)所有衡量標準的評估結果加權平均可計算得出城市的總評分。例如底特律的總得分為35.13。

根據(jù)最后得分可為100座城市排名，四個標準下也評出分項榜單。以下是WalletHub評選的駕駛環(huán)境最差的十座城市，還有拖累城市總排名的分項。

1. 密歇根州城市底特律

在交通事故死亡率、汽車失竊率、事故可能性等“安全”項評估中，底特律排名倒數(shù)第二，在交通狀況和基礎設施方面也名次較低。

2. 加利福尼亞州舊金山

舊金山在“車牌及維護成本”項評估中排在倒數(shù)第一，在100座城市中交通狀況和基礎設施排在第92位。

3. 加利福尼亞州奧克蘭

與舊金山一灣之隔的奧克蘭在“車牌及維護成本”項評估中排名倒數(shù)第二，還同底特律以及新墨西哥州城市阿布奎基并列為汽車失竊率最高的城市。

4. 賓夕法尼亞州費城

費城上榜部分源于安全方面的排名低，而且車牌成本高，交通擁堵。

5. 華盛頓州西雅圖

由于在交通狀況、車牌以及車輛維護的成本方面表現(xiàn)不佳，西雅圖成為全美駕駛環(huán)境第五差城市。

6. 馬薩諸塞州波士頓

除了交通狀況差，車牌成本高，波士頓在買車與車輛維護的渠道方面得分最低所以上榜。

7. 紐約州紐約市

紐約人再也不能抱怨洛杉磯的交通狀況差了，因為紐約市在“交通狀況和基礎設施”方面排名墊底。

8. 新澤西州紐瓦克

紐瓦克因為安全狀況差和交通擁堵嚴重上榜。

9. 加利福尼亞州洛杉磯

洛杉磯的交通狀況并不算最差，但其公路擁堵，加之車牌成本高，所以還是入選了十大駕駛環(huán)境最差城市。

10. 伊利諾伊州城市芝加哥

芝加哥僅次于紐約，是交通狀況第二差的城市。

駕駛環(huán)境最好的十大城市主要分布于北卡羅來納、得克薩斯和佛羅里達三個州。其中北卡羅來納州的羅利市環(huán)境最好，緊隨其后的是得克薩斯的科珀斯克里斯蒂和佛羅里達的奧蘭多。（財富中文網(wǎng)）

Unlike some studies that focus solely on traffic, WalletHub looked at the 100 U.S. cities (excluding surrounding metro areas) with the highest population, and measured them in four different categories: cost of ownership and maintenance, traffic and infrastructure, safety, and access to vehicles and maintenance.

These four categories were broken down into a total of 29 sub-metrics—number of car thefts and the cost of gas, for example—each of which had a weighted value. For each metric a city was graded on a 100-point scale (100 being the best), and a city’s overall score was determined by calculating the “city’s weighted average across all metrics.” (For example, Detroit got a total score of 35.13.)

From there the 100 cities were ranked overall, and then across the four categories. Here are WalletHub’s 10 worst cities for driving—and the main category that dragged them down:

1. Detroit, Mich.

Detroit ranked second to last in the “safety” category, which was measured by criteria including traffic fatality rate, rate of car theft, and the likelihood of accidents. It also ranked poorly for traffic and infrastructure.

2. San Francisco, Calif.

San Francisco was dead last in the “cost of ownership and maintenance” category, and the city was also ranked 92 out of 100 in traffic and infrastructure.

3. Oakland, Calif.

And just across the bay from San Francisco, Oakland was ranked second to last in “cost of ownership and maintenance.” It also tied with Detroit and Albuquerque, N.M. for the highest rate of car theft.

4. Philadelphia, Pa.

Philadelphia’s position is due in part to its poor safety ranking, high cost of ownership, and amount of traffic.

5. Seattle, Wash.

Traffic and the cost of owning and maintaining a car contribute to Seattle’s ranking as the fifth worst city for driving.

6. Boston, Mass.

In addition to traffic, and cost of owning a vehicle, Boston was the city in the bottom 10 with the worst “access to vehicles and maintenance” rating.

7. New York, N.Y.

New Yorkers can no longer complain about Los Angeles traffic; the city was ranked last in “traffic and infrastructure.”

8. Newark, N.J.

Newark’s safety ranking and traffic congestion landed it on this list.

9. Los Angeles, Calif.

Though Los Angeles did not rank as the worst traffic, its infamous road congestion along with the high cost of ownership earned Los Angeles its number nine spot.

10. Chicago, Ill.

Chicago follows New York as the second worst city for traffic.

The top 10 cities for driving were all located in North Carolina, Texas and Florida. Raleigh, North Carolina was number one, followed by Corpus Christi, Texas, and Orlando, Florida.
