BS EN 16276:2013EN 16276:2013 (E) 4 Introduction The Directive 2004/5

16、4/EC of the European Parliament of 29 April 2004 aims at ensuring a minimum level of safety for road users in tunnels in the Trans-European Network by the prevention of critical events that may endanger human life. With regard to lighting, there are two main cases: normal lighting and safety lightin

17、g. Normal lighting is provided to ensure appropriate visibility during the day and night for drivers in the entrance zone as well as in the interior zone. Safety lighting is divided into two parts: standby lighting and evacuation lighting. Standby lighting is provided to ensure a minimum visibility

18、for tunnel users to evacuate the tunnel in their vehicles in the event of a breakdown of the power supply. Evacuation lighting is provided to guide tunnel users during evacuation of the tunnel on foot in emergency circumstances such as fire. Evacuation lighting includes evacuation route marker light

19、s, emergency exit lighting, emergency exit marker lights and evacuation route lighting. BS EN 16276:2013EN 16276:2013 (E) 5 1 Scope This European Standard specifies evacuation lighting in road tunnels longer than 500 m and with an AADT (Annual Average Daily Traffic) higher than 500 vehicles to facil

20、itate the safe evacuation of vehicle occupants in evacuation situations such as fire. It addresses the fundamental issues of evacuation lighting for evacuation routes, emergency exits and cross connections, as well as giving some practical advice regarding aspects of installation and maintenance in

21、road tunnels. It is intended to be used in conjunction with CEN/CR 14380:2003 or relevant national standards for road tunnel lighting. The recommendations may be applied to tunnels up to 500 m in length, especially where conditions such as high traffic volume, or severe curvature or gradient apply.

22、It specifies lighting levels and general provisions for evacuation lighting installations that, based on experience, are considered to be necessary for the safety of people driving through road tunnels in case of an incident and particularly in case of fire. However, as there are different types of

23、road tunnels, both in construction and traffic conditions, various types of incident may occur. This standard should be considered as a list of minimum prescriptions for evacuation lighting in tunnels, to be completed by means of specific risk analysis for the particular tunnel. The design of markin

24、g and safety signs is not part of this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

34、ained 4 Lighting of specific areas under emergency circumstances 4.1 General In emergency circumstances, lighting covers two main functions: to provide guidance and visibility for drivers able to exit the tunnel in their vehicles (standby lighting); to provide guidance and visibility for people leav

35、ing their vehicles and evacuating the tunnel as pedestrians. All the lighting systems described in this section shall be supplied from an uninterruptible power supply, in order to guarantee continuity of lighting. In emergency circumstances, the duration of the evacuation mode shall be in accordance

36、 with national requirements. If a national standard does not exist, a duration of at least 30 min is to be realised, or otherwise in accordance with the results of a specific evacuation study. Inspection and testing of tunnel evacuation lighting systems shall be made in accordance with EN 50172, unl

37、ess existing national regulation states otherwise. 4.2 Driving task lighting 4.2.1 Carriageway For guidance on the appropriate carriageway lighting requirements to apply in the event of a breakdown of the normal power supply (standby lighting), reference should be made to CEN/CR 14380:2003, Clause 7

38、 or to national recommendations or standards. BS EN 16276:2013EN 16276:2013 (E) 9 4.2.2 Vehicular cross connections In emergency circumstances, the values of average maintained horizontal illuminance and uniformity of illuminance on a vehicular cross connection shall be at least equal to the values

39、on the carriageway in the interior zone of the main tunnel. 4.3 Pedestrian guidance 4.3.1 General When visibility is normal, the normal lighting or standby lighting of the main tunnel can be assumed to be adequate for this purpose. It has been observed that vehicle occupants tend to stay in their ve

40、hicles and are reluctant to leave at an early stage of an emergency. Specific systems instructing them to leave their vehicles are strongly recommended. 4.3.2 Evacuation route within the main tunnel In emergency circumstances, the main tunnel carriageway becomes a footway for fleeing pedestrians to

41、the emergency exits. In any emergency, as a complement to the normal lighting or standby lighting, and in particular in situations where visibility is impaired, evacuation route marker lights are requested to provide tunnel users with guidance to facilitate their evacuation of the tunnel on foot tow

42、ards the emergency exits. The evacuation route shall be clearly and unambiguously marked with evacuation route marker lights at a spacing not exceeding 25 m and not higher than 1,5 m above the carriageway level. This shall be done at least on one side of the tunnel where the emergency exits are situ

43、ated. Where there are three or more traffic lanes, consideration can be given to provide evacuation route marker lights on both sides of the tunnel, provided that clear direction is given towards emergency exits. At all times, evacuation route marker lights along the evacuation route shall be operat

44、ional, either to be illuminated in an emergency, or permanently illuminated. Where the markers are permanently illuminated, in order to limit disability glare to drivers, the intensity in the critical directions shall be limited. For that purpose, luminous intensities of each marker shall not exceed

45、 40 cd during normal conditions, in a cone of 2 15 with the axis formed by the drivers observation direction (see Figure 4). During evacuation circumstances, the markers intensity can be increased. To enhance the visibility in smoke, the minimum maintained luminous intensity of each marker, in all d

46、irections from which it could be seen by a fleeing pedestrian, shall be determined by their spacing. The minimum maintained luminous intensity shall be 0,1 cd for each meter of spacing between markers, with a minimum luminous intensity of 1 cd. EXAMPLE For a distance of 15 m between two markers, the

47、 minimum maintained luminous intensity is 1,5 cd. In case of tunnels wider than the spacing of markers, the minimum luminous intensity shall instead be determined by the tunnel width and not the marker spacing, using the same rule as before.

Alternative methods of marki

49、ng the evacuation route in the main tunnel are acceptable if visibility under all conditions, including smoke, is equivalent to or better than the system described above. 4.3.3 Emergency exits 4.3.3.1 General Exits clearly identified by dedicated emergency exit lighting will help encourage vehicle occupants to leave their vehicles when necessary. There are two objectives: the first is to make the emergency exits adequately visible to familiarise users with their presence under normal conditions; the second is to highlight the emergency exits when needed
