De Centrale As (N356)高速公路总长24公里，位于荷兰弗里斯兰东部的Dokkum与Nijega两座城市之间。这片在夜晚仰望天空仍能看见璀璨星河的区域成为了荷兰高度城市化郊区中一个独特的存在。NEXT与Arup也因此在其灯光设计中采取了独特的设计方法。他们并没有从道路对灯光的需求以及空间的可识别性出发，而是立足于黑暗，去质疑道路灯光照明的必要性。
De Centrale As (N356) is a new highway in East Friesland, with a length of 24km between the cities of Dokkum and Nijega. In the highly urbanised Dutch countryside, this is an exceptional area where it is still possible to experience the natural night sky. NEXT and Arup therefore took a special approach in the lighting design. Their point of departure was not ‘where’ and ‘what type of’ lighting is needed. Rather, they examined the road from the standpoint of darkness. Was lighting even necessary?

设计师将道路视为原野中的以头灯照亮前路的闯入者。他们通过反光设施作为提示和信号，指引前路，仅在必要的地方引入了低亮度的灯光照明，以保证车辆的安全。这种措施不仅大大降低了道路的光污染，同时也减弱了驾驶者因眩光而导致的不适。 Princess Margriet运河下部空间在夜间的照明度仅为日间的30%，大幅降低的明暗对比使得其周边区域无需增加照明设施。而在车辆交汇区等地区则已低亮度的照明保证安全，例如在转盘区域中多头灯柱如同灯塔般耸立在转盘中央。在自行车道与机动车道交叉处的小灯不仅照亮了道路，同时也作为视觉暗示，提醒驾驶员集中注意力。木制的路灯杆不仅赋予了道路独特的视觉特征，同时也将其对 Noardlike Frisian Wâlden田园区域的视觉影响降至了最低。
The main approach to the lighting is that the road is a guests in the landscape, and that users light their own way with their headlights. Taking this into account, safety on the roadway is addressed by providing visual cues through reflection and, where necessary, low light levels. This minimizes light pollution and also visual discomfort glare to drivers. For example, the daytime light levels of the Aqueduct under the Princess Margriet Canal are reduced down to 30% at night. This reduces the contrast between light and dark, making additional lighting around the Aqueduct unnecessary. Where lighting is necessary for safety, such as conflict areas, low light levels are used. This is the case at roundabouts where just one multi-headed lamppost has been placed as a beacon in the center. A small pole light only where cyclist and cars cross paths is added to light the intersection but also to give a visual cue to motorists that their extra attention is needed. The wooden lampposts enhance De Centrale As’ visual identity, while minimising the highway’s impact on the Noardlike Frisian Wâlden.

The lighting design, however, is not just functional. At key moments where the main road passes through a landmark, the lighting accentuates a special feature of the infrastructural design, such as the cor-ten steel in the Doniawei. The lit landmarks provide an intuitive sense of location along the road.

除了将灯光对生态的影响降至最低外，NEXT 与 Arup联手打造的灯光设计同时也最小化了能源消耗、管线的使用量以及建造成本，让De Centrale As成为了非干扰性道路灯光设计的典范，也进一步促进了道路与景观的相互融合。
In addition to the minimal ecological impact, NEXT and Arup’s lighting design also minimized energy use, material usage for cables, and overall cost . This makes De Centrale As an exemplary project for roads without obtrusive light. This approach also fits within the broader vision to fully integrate the road and the landscape.
