去美国旅游，在这几个城市开车要当心！

个人理财网站WalletHub不久前做了一项特殊研究，评估对象是人口排名前100位的美国城市（不计大都市周边地区），主要标准包括获得车牌及维护的成本、交通状况与基础设施、安全、买车与车辆维护的渠道等四个方面。

以上四大衡量标准又可细分为总共29个小标准，比如车辆失窃数量和汽油成本，每个亚标准都有一个权重值。每项标准下城市都会得到从零到100范围内的评分，100分为最佳。根据所有衡量标准的评估结果加权平均可计算得出城市的总评分。例如底特律的总得分为35.13。

根据最后得分可为100座城市排名，四个标准下也评出分项榜单。以下是WalletHub评选的驾驶环境最差的十座城市，还有拖累城市总排名的分项。

1. 密歇根州城市底特律

在交通事故死亡率、汽车失窃率、事故可能性等“安全”项评估中，底特律排名倒数第二，在交通状况和基础设施方面也名次较低。

2. 加利福尼亚州旧金山

旧金山在“车牌及维护成本”项评估中排在倒数第一，在100座城市中交通状况和基础设施排在第92位。

3. 加利福尼亚州奥克兰

与旧金山一湾之隔的奥克兰在“车牌及维护成本”项评估中排名倒数第二，还同底特律以及新墨西哥州城市阿布奎基并列为汽车失窃率最高的城市。

4. 宾夕法尼亚州费城

费城上榜部分源于安全方面的排名低，而且车牌成本高，交通拥堵。

5. 华盛顿州西雅图

由于在交通状况、车牌以及车辆维护的成本方面表现不佳，西雅图成为全美驾驶环境第五差城市。

6. 马萨诸塞州波士顿

除了交通状况差，车牌成本高，波士顿在买车与车辆维护的渠道方面得分最低所以上榜。

7. 纽约州纽约市

纽约人再也不能抱怨洛杉矶的交通状况差了，因为纽约市在“交通状况和基础设施”方面排名垫底。

8. 新泽西州纽瓦克

纽瓦克因为安全状况差和交通拥堵严重上榜。

9. 加利福尼亚州洛杉矶

洛杉矶的交通状况并不算最差，但其公路拥堵，加之车牌成本高，所以还是入选了十大驾驶环境最差城市。

10. 伊利诺伊州城市芝加哥

芝加哥仅次于纽约，是交通状况第二差的城市。

驾驶环境最好的十大城市主要分布于北卡罗来纳、得克萨斯和佛罗里达三个州。其中北卡罗来纳州的罗利市环境最好，紧随其后的是得克萨斯的科珀斯克里斯蒂和佛罗里达的奥兰多。（财富中文网）

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.
