Holland - N200 Case Study

Country / Region: 
Holland, Noord-Holland Province

Application:
Hardwired Night Delineation

Location of installation:
N200 Overveen and Bloemendaal

Astucia Products:
Hardwired F Series Flush Studs

Project background:

The N200, is a 3.5km stretch of rural, twisting dual carriageway between Overveen and Bloemendaal in the Noord-Holland Province of the Netherlands. Keen to increase safety of its roads whilst at the same time casing minimum impact on the environment the Province carried out a number of trials for alternatives to street lighting.

Installation:

In this instance Astucia Hardwired flush mounted Intelligent Road Studs™ are installed to provide delineation on the bends in the road. To further reduce both energy costs and light pollution alike the studs and are activated by loops in the road and therefore only illuminate as vehicles approach, however the loops are so spaced that drivers are given the impression that the studs are constantly illuminated.

The Astucia hardwired intelligent road stud, or the solar powered alternative, with their built in Light Emitting Diodes  provide drivers with up to 900 metres of visibility. This is compared to generally around 90 metres from the traditional, retro-reflective, passive road stud which is limited by the headlight beam of the vehicle. At 100 km/h (62 mph) a visible distance of 90 m only represents a reaction time of 3.2 seconds, which is not enough time to properly judge certain road hazards such as the radius of a bend. With the increased visibility of the Astucia road stud this reaction time is increased to over 30 seconds.

Benefits:

Marc Vissers, Director of Intertraffic Systems B.V, the authorised Dutch distributor of Astucia (UK) Ltd. , who conducted the installation advised: “The active road studs from Astucia are proven to reduce accidents by providing information to drivers about the road ahead directly in their natural field of vision whilst at the same time keeping light pollution and life time operating costs to a minimum. On all stretches where the studs have been installed the accident rate has reduced to zero.”

The Netherlands Province of Noord-Holland has been awarded the Dutch Association for Lighting Knowledge’s (NSVV) National Light-award 2005 for the innovative way it has applied Astucia’s active marking road studs on the N200.

Commenting on the award, Noord-Holland Province project manager Paul Rutte said: “Since 1999 we have undertaken a number of trials with alternative lighting methods on a number of provincial roads, including roundabouts and cycle lanes. The Province goes for maximum safety, minimal light pollution and minimal energy consumption. We obtained a number of conclusions, firstly the active road marking represents an energy reduction of over 90 percent relative to conventional lighting especially as the installed studs are operated by loops in the road and thus only illuminate when necessary. Also that the safe distance between the hardwired studs is far greater than initially expected. It appears that an acceptable distance apart through bends on roads with a maximum speed of 80 Km/h can be 15 metres, and on straights up to 25 to 30 metres apart.”

The system is also installed near Castricum, Callantsoog, Akersloot, Amstelveen, Nieuw Vennep and Grootebroek. Rutte continued to say: “The Province will endeavour over the next three years on eliminating 20 dangerous (dark) road stretches with alternatives to conventional lighting. Active marking fills the gap between conventional lighting and no lighting at all.”

The NSVV collects and distributes on a national level all available knowledge on lighting, it concluded that thanks to the approach of the Province of  Noord-Holland, The Netherlands takes a leading role at applying public lighting on roads. Also internationally this approach is widely appreciated. As yet there is no official guideline for active marking; however the NSVV has published the ‘Noord-Holland Recommendation for Active Marking’. This can be ordered through info@nsvv.nl
