On 8 October 2004, the Directorate-General of Public Works and Water Management (Rijkswaterstaat) management team decided to introduce a new implementation framework for motorway lighting. Basically this means that, more so than previously, the intensity of motorway lighting will be adjusted dynamically to current local factors such as traffic intensity, weather conditions, roadworks, accidents, and location in a nature area. The implementation framework indicates where and when there must be full lighting and where and when lighting may be dimmed. The quality criteria for full (100%) lighting are described in NPR13202-1 and are not included in the implementation framework. The lighting implementation framework outlines in general terms a desirable future scenario for motorway lighting at a functional traffic level. This Manual of Dynamic Lighting has been written to fill the gap between the functional implementation framework on the one hand and operational practice on the other. Its aim is to offer points of reference to all those involved professionally in the design, installation and management of public lighting. Aside from its connection with the implementation framework, this Manual does not have the status of a management decree. The aim is not for it to be declared a ‘standard requirement’ in specifications. It is a summary of the ‘best practices’ that came out of early dynamic lighting projects. Readers are free to take advantage of them or not as they see fit. (Author/publisher)
