Samenvatting
A technical review was conducted into the requirement for local highways authorities to comply with the current statutory requirements for the lighting of traffic signs and bollards. From this review, a guidance document was produced that provides highway/road authorities with advice on the current retro-reflective, solar powered and low energy sign lighting materials. From the technical review, a number of recommendations are made in order to reduce carbon footprint, energy consumption, and sign clutter. (Author/publisher)
