美國騎車上班人數增加60%

The number of US commuters who ride a bicycle to work rose by 60% over the last decade, the Census has reported.

An estimated 786,000 people biked to work in 2008-12, up from 488,000 people in 2000, the bureau said.

Cyclists account for about 0.6% of all US commuters, compared to 2.9% in England and Wales, a 2013 report found.

The rise comes as a growing number of states and local communities build infrastructure such as bike lanes to promote cycling.

"In recent years, many communities have taken steps to support more transportation options, such as bicycling and walking," Census Bureau sociologist Brian McKenzie wrote in a statement accompanying the report.

The US West had the highest rate of bicycle commuters at 1.1%, and the South the lowest with 0.3%.

The city of Portland, Oregon, registered the highest rate of bicycle commuting with 6.1%,, up from 1.8% in 2000.

Men were found to be more likely to bike to work than women, and the median commute time for bicyclists was found to be 19.3 minutes.

Meanwhile, the study found that 2.8% of commuters walk to work, down from 5.6% in 1980.

The North-East was has the highest rate of commuters who walked to work, at 4.7%.

Boston, Massachusetts, was the top walk-to-work city at 15.1%, while the US South had the lowest regional rate at 1.8%.人口普查報告顯示，美國騎車上班人數在過去十年間增加了60%。

美國國家統計局指出，2008年到2012年，估計有78.6萬人騎車上班，而2000年這一數字僅爲48.8萬。

2013年一份報告表明，美國上班族中有大約0.6%人騎車，英格蘭和威爾士有2.9%。

騎車人數的增多是因爲越來越多的州和社區建造了像自行車專用車道這樣的基礎設施來促進騎車。

人口普查局社會學家布萊恩·麥肯齊在報告的聲明中寫道，“最近幾年，許多社區已經採取措施支持更多的交通方式，比如騎車和步行”。

美國西部騎車出行率最高，達1.1%，南部最少，僅有0.3%。

俄勒岡州波特蘭市騎自行車上班的比例最高，從2000年的1.8%增加到6.1%。

男人比女人更願意騎車上班，騎自行車出行平均時間大約爲19.3分鐘。

同時，研究發現，步行上班人數由1980年的5.6%減少到了2.8%。

美國東北地區步行上班率最高，達4.7%。

馬薩諸塞州波士頓步行上班率最高，達15.1%，而美國南部地區最低，爲1.8%。
