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, curbs¹, 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 implement² the system was Drachten, a small city with a population of 45,000 and a notoriously congested main intersection³. The results have been lauded⁴ 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。
