城市里的车越来越多，道路也越发拥挤了，哪怕摆再多的交通信号灯或者标识估计都不能避免交通拥堵的发生。怎么办呢？有创意的人士想出了一个办法：把道路上的所有信号标识都撤掉，让人们自己去决定要怎么行驶、以什么速度行驶，没有约束往往是最厉害的约束。于是，naked street理念就诞生了。

Naked street refers to a street that has no signs, road markings, or traffic lights.

Naked street（裸街）指没有任何交通标识、路标或者信号灯的街道。

Today, many European cities are doing away not only with traffic lights, but also sidewalks, curbs, signage and painted markings of any kind. The concept, known as naked streets, was pioneered by Dutch engineer Hans Monderman. One of the first municipalities to implement the system was Drachten, a small city with a population of 45,000 and a notoriously congested main intersection. The results have been lauded in progressive urban planning circles: the average car speed dropped, as did the number of accidents.

如今，欧洲很多城市都开始弃用交通信号灯、便道、路缘、标识以及各种喷涂的指示标识。这种被称为“裸街”的概念是由荷兰一位叫汉斯•蒙德曼的工程师首先提出的。第一个将“裸街”的理念付诸实践的是拥有4.5万人口的小城德拉赫滕，那里的主要路口总是拥堵不堪的状态。实行结果受到了城市计划界进步人士的一致推崇：车辆平均速度和交通事故数量同时下降。
