Inventarisatie achtergrondschilden
report
Rijkswaterstaat (RWS) wants to harmonize its internal specifications for background shields and white edges used on information carriers along the road. RWS has asked TNO to build up, from its expertise, an analysis of existing literature that will act as a motivation for using background shields and white edges.
RWS has asked the following from TNO:
1. What research has been carried out by TNO on the necessity and design of background shields? This includes size, location, dimensions of the white edge, retro-reflection, etc.
2. Are the outcomes of this research still relevant in the current situation (e.g. where LED lights are in use)? What does TNO expect for the future?
3. What knowledge is missing for an answer to question 2?
In this TNO report question 1 is answered. The relevant TNO-studies on background shields are inventoried. In another TNO-report (TNO 2015 R11704) the questions 2 and 3 are answered.
