In special cases may Roads or the Agency delegates authority, decide that certain tunnels with average AADT below 300 vehicles shall be covered by the regulation.
For tunnels that are open to public traffic as of 1 January 2010, it shall, pursuant to provisions set out in § 12, ref. Annex II, an assessment of whether they are in accordance with the requirements of the regulations.
§ 3. Definitions In these regulations:
-
County: Public road as by the Public Roads Act are classified as county.
-
Municipal road in Oslo: Public roads in Oslo, which by the Public Roads Act are classified as municipal road.

Rescue services: All local services, which are either public or private or part of the tunnel staff, who respond by an accident, including police, fire and rescue.
-
Tunnel length: The length of the longest lane, measured on the fully enclosed part of the tunnel.
-
Risk: Analysis of the risks of a particular tunnel, taking into account all design factors and traffic conditions that affect safety, including in particular traffic characteristics and type, tunnel length and tunnel geometry and the forecast for the number of heavy goods vehicles per day.
§ 4. Managing Authority The county, in Oslo municipality, is so far otherwise stated, the administrative authority responsible and coordinating tasks for ensuring that all aspects of security in the tunnel at the county and in Oslo municipal road is taken care of, and to take the necessary measures to ensure compliance with the contents of these regulations.
Roads, or the Agency delegate authority shall grant permission for new or rehabilitated tunnel on county roads and in Oslo municipal road, may be adopted in accordance with the procedure set out in Annex II to Regulation. Before permission is granted shall obtain a statement from the fire authority.
Roads, or the Agency delegates authority may suspend or restrict the use of a tunnel at the county and in Oslo municipal road, including specifying the conditions under which normal traffic may be resumed if safety requirements are not met.
The county and the City of Oslo shall ensure that relevant organ

Appendix I. Measures referred to in § 8
1.
Basis for adopting security measures
1.1.
Security Parameters
1.1.1.
Safety measures to be implemented in a tunnel shall be based on a systematic assessment of all aspects of the system composed of the infrastructure, use, road users and vehicles.
1.1.2.
The following parameters should be considered:
-
Tunnel length,
-
Number of races,
-
Number of lanes,
-
Sectional geometry,
-
Vertical and horizontal profile
-
Construction type,
-
Way or two-way traffic,
-
Traffic volume per race (including distribution in time)
-
Risk of congestion (per day or seasonal)
-
Atkomsttid for emergency services,
-
Presence and percentage of heavy trucks,
-
Characteristics of access roads,
-
Lane width,
-
Speed aspects,
-
Geographical and meteorological environment.
1.1.3.
If a tunnel has a special characteristic as regards the above parameters shall be prepared a risk analysis in accordance with § 10 to determine whether it is necessary with additional safety measures and / or accessories to ensure a high level of safety in the tunnel. This risk analysis shall take into consideration possible accidents, which clearly affect safety for tunnel users and which might occur during the operating stage and the nature and magnitude of their possible consequences.
1.2.
minimum
1.2.1.
The security measures laid down in the following paragraphs shall be implemented as a minimum to ensure a minimum level of safety in all the tunnels covered by these regulations. Limited exemptions from these requirements may be permitted, provided that the following procedure be followed:
-
Need for exemptions to be documented through a risk analysis
-
If exemption is accepted it must be documented that the mitigation measures provide the same or better overall safety where fire and accidents seen in context.
1.2.2.
To provide a unified interface in all tunnels to which this regulation shall not be exempted from the requirements concerning the design of the safety equipment available to road users in consecutive numbers where emergency stations, signs, lay-bys, emergency exits and radio broadcast via relay necessary.
1.3.
traffic volume
1.3.1.
Where "traffic volume" is mentioned in this Annex refers to the annual average daily traffic through a tunnel per lane. In determining the traffic volume, each motor vehicle is counted as one unit.
1.3.2.
If the number of heavy trucks over 3.5 tons exceeds 15% of the annual average daily traffic, or seasonal daily traffic significantly exceeds the annual average daily traffic, assessed the additional risk and taken into account by increasing tunnel traffic using subsequent numbers where average AADT included.
2.
Infrastructure measures
2.1
Number of tubes and lanes
2.1.1.
Projected traffic volume and safety is the main criteria for determining whether it should be built underground with one or two races, taking into account aspects such as percentage of heavy goods vehicles, gradient and length.
2.1.2.
When a 15 year projections show that the traffic volume will exceed 10 000 vehicles per day per lane, it shall be for tunnels at the design stage in all cases is a dual tube tunnels with unidirectional traffic on the date when this value is exceeded.
2.1.3.
With the exception of the emergency lane, the same number of lanes shall be maintained inside and outside the tunnel. Any change in the number of lanes shall occur at a sufficient distance before the tunnel portal; this distance shall be at least the distance traveled by a vehicle traveling at 10 seconds when it runs in the maximum permitted speed. When geographic circumstances prevent this, must be taken additional and / or reinforced measures to improve security.
2.2.
Tunnel Geometry
2.2.1.
When designing a tunnel cross-sectional geometry and the horizontal and vertical, and its access roads, should be given particular attention to safety, as these parameters have a significant impact on the likelihood of accidents and how serious they are.
2.2.2.
More than 5% increase in the longitudinal direction shall not be permitted in new tunnels, unless no other solution is geographically possible.
2.2.3.

2.3.
Escape routes and emergency exits
2.3.1.
In new tunnels without an emergency lane, there should be an emergency walkway, elevated or not, to use for tunnel users in case of breakdown or accident. This provision shall not apply where the characteristics of the tunnel construction not allow it or allow it only at disproportionate cost and the tunnel is unidirectional and is equipped with a permanent surveillance and system lane closure.
2.3.2.
In existing tunnels where there is neither an emergency lane nor an emergency walkway, must be taken additional and / or reinforced measures to ensure safety.
2.3.3.
Emergency exits shall enable tunnel users to leave the tunnel without their vehicles and reach a safe place in case of an accident or fire. They also provide emergency services access to the tunnel on foot. Examples of such exits are:

Where emergency exits are provided, the distance between two emergency exits shall not exceed 500 meters.
2.3.9.
It will be used appropriate means, such as doors, to prevent smoke and heat from reaching the escape routes behind the emergency exit, so that the tunnel users can safely reach the outside and the emergency services can have access to the tunnel.
2.4.
Access for emergency services
2.4.1.
In dual tube tunnels where the tubes are at the same level or almost the same level, there should at least every 1,500 meters are cross-connections suitable for the use of emergency services.
2.4.2.
Wherever geographically possible, outside each portal of a two- or multi-tube tunnel be possible to cross the central reserve (median strip). This measure will allow emergency services to gain immediate access to either tube.
