如今，隨著機(jī)動(dòng)車數(shù)量的增多，為了避免擁堵，人們不多增加行車道，結(jié)果卻造成更多混亂。很多人對此都存在一個(gè)誤區(qū)：認(rèn)為道路越寬，通行量越大。其實(shí)，合理規(guī)劃才是關(guān)鍵，有時(shí)適當(dāng)為道路“瘦身減肥”，反而使其更加通暢。

Road diet refers to a reduction in the number of travel lanes available on a road, usually by converting one or more existing travel lanes into turn lanes, bike lanes, or street parking.
“道路瘦身”是指道路上可用車道數(shù)量減少，通常是將現(xiàn)有的一個(gè)或多條車道變成轉(zhuǎn)彎車道、自行車道或路邊停車道。

在道路規(guī)劃方面，歐美都經(jīng)驗(yàn)豐富，幾年前便已引入這種理念。

The U.S. Department of Transportation (DOT) announced an 18-month campaign to improve road safety across the country. One of the things DOT plans to do is create a guide to "road diets" that it will distribute to communities and local governments.
美國交通部公布了一項(xiàng)歷時(shí)18個(gè)月，旨在改善全美道路安全的活動(dòng)。美國交通部計(jì)劃要做的其中一件事就是制作一本“道路瘦身”指南，并將其分發(fā)給各個(gè)社區(qū)和地方政府。

DOT says that road diets can reduce traffic crashes by an average of 29 percent, and that in some smaller towns the design approach can cut crashes nearly in half.
美國交通部公布稱，道路瘦身可使平均交通事故發(fā)生量降低29%。在一些小型城市，這種設(shè)計(jì)方法可將事故數(shù)量減半。

Road diets have long been practiced in Europe and are more popular in peer cities like San Francisco and Seattle.
據(jù)悉，歐洲一直在進(jìn)行道路瘦身，在洛杉磯和西雅圖等新貴城市該規(guī)劃更受歡迎。
