The report is

17、restricted to the first stretch of tunnels, called the threshold zone. The report firstly reviews the fundamental experiments on which the 1973 CIE Recommendations for Tunnel Lighting (as far as the threshold zone is concerned) are based. New investigations are described with which the original fund

18、amental experiments may be applied more realistically. Results of driving experiments in a real tunnel under various lighting conditions are summarized. To complete the description of methods based on visibility two recently published methods that dispense with the original fundamental experiments a

19、re reported. Finally mention is made of an approach not directly based on visibility but on traffic flow. The report does not give a straightforward answer to all problems related to the. lighting of threshold zones of tunnels;, it gives the state of the art and as such it will form an important bac

20、kground for future tunnel lighting recommendations.

Er informiert ber die Beleuchtungsanforderungen eines Kraftfahrers, der sich am Tage einer Tunneleinfahrt nhert. Der Bericht beschrnkt sich auf den

25、 ersten Teil des Tunnels, die sogenannte Einsichtstrecke. Dieser Bericht berprft erstmalig die grundlegenden Untersuchungen, auf denen die CIE-Empfehlungen fr Tunnelbeleuchtung (1973) basieren (im Bereich der Einsichtstrecke). Es werden neue Untersuchungen beschrieben, mit denen die frheren Basisunt

Um die Beschreibung der Methoden zu vervollstndigen, die auf der Sichtbarkeit basieren, sind 2 krzlich verffentlichte Verfahre

It does not cove

Taking into account the fact that the requirements for the lighting in the threshold zone vary according to many factors, not only visual conditions of drivers, but also weather conditions, road and traffic conditions, driving customs, construction an

46、opriate luminance has to be provided in the threshold zone of the tunnel. The threshold zone is defined as the first stretch of the tunnel and it is that length of bright background which enables objects in the tunnel to be perceived by an approaching driver, at a distance equal to approximately the

47、 safe stopping distance from the tunnel facade. The safe stopping distance has a strong dependence on the speed of traffic (CIE 1980). The 1973 CIE Recornendations for Tunnel Lighting are, as far as the lighting level required in the threshold zone is concerned, based mainly on model tunnel experime

48、nts carried out in the early sixties by Schreuder. These experiments, based on the detection probability of small objects, were done with a uniform luminance surrounding the tunnel entrance, In the present report the validity of these experiments is reconfirmed (Chapter 1). For practical tunnel- lig

49、hting design purposes, however, it is necessary to compare the actual non-uniform luminance distribution of tunnel surrounds with the uniform luminance as used in the model experiments. From practical experience it has become clear that the 1973 Recommendations do not give a satisfactory answer to the question of how to do this comparison. As a result too much weight is often given to the luminance of the road surface in front of a tunnel and sometimes leads to needlessly hig
