Definitions

" Vehicle restraint system " means a system mounted on a road that deviated from the
A certain degree of control of a deviated vehicle.

" Safety barrier " means a continuous vehicle restraint fitted along the edge of the road or on the
Which may include a travel kirine.

"Vehicle parapet" means bounbsticks mounted on the edge or retaining wall of the bridge, or
The same vertical structure, which may additionally contain protection and confinement
For pedestrians and other road users.

Terminal (terminal) -the end-of-the-collision

" Transition " means the connection between two different design and/or performance boundles.

"Crush cushion" means an energy-absorbent road vehicle that is mounted on a
Hazard (s).

" Exit area " means the vehicle's movement area after a collision with THE terminal EVS-env 1317-4
Collision test.

" Critical distance " means the distance within which it is necessary to check that the boundles are
Danger (area requiring protection, obstruction).

Decisive Distance – between the inner edge of the driveway and the danger position (area requiring protection, obstacle)
Distance.

" Collision level " means the strength of an accident, the physical loads of the occupants and the driver, the
Theoretical parameter for assessing the risk of death.

" Connection structure " means the cross-section bounblines joined with or without transition
Bridges.

Containment Level – The containment level is characterized by the ability to control the Bounde
Collision angle and collision speed according to the provisions of the EVS-EN 1317.
Collision test.

Sideway Residual displacement – lateral deformation of the conical AND terminals EVS-EN
The collision test according to 1317-3 or EVS-ENV 1317-4.

Dynamic deflection -dynamic deflection of vehicle restraint systems is DETERMINED by EVS-EN
1317-2 by means of a collision test complying with the limit system on the traffic side of any
To the maximum lateral dynamic shift.

' Danger place ' means the place or area adjacent to the roadway, where the vehicle may be exposed to
Third party, protected area or vehicle occupants and drivers.

" Pedestrian Parapet " – a pedestrians or "other users" system along the
The edge of a walkway, a footpath or a foot that restricts pedestrians and other users from engaging in driveways or
Likely to impede the crossing of the hazardous area.

Performance CLASS EVS-EN 1317-2 – The performance class of the bounce partitions and transitions is
Levels of containment, working width and collision strength.

Class ENV 1317-4 -Performance class of terminals is determined by the impact test
Performance class, lateral displacement, exit area, and collision strength level.

Performance CLASS EVS-EN 1317-3- The performance class of the collision
Collision speed, lateral displacement, reconnection and collision strength levels.

Working Width is the maximum lateral distance of the collision boundary on the non-deformed traffic side of any
Which part and the maximum dynamic position of any part of the boundary EVS-EN 1317-2
Collision test.
