| Title | This document is applicable to tram vehicles and to tram-Train vehicles operating on tram and suburban networks in accordance with EN 17343. On-track-machines, infrastructure inspection vehicles and road-rail machines in accordance with EN 17343 and demountable machines/machinery are not in the scope of this document. This document describes passive safety measures to reduce the consequences of collisions with pedestrians. These measures provide the last means of protection when all other possibilities of preventing an accident have failed, i.e. — design provisions for the vehicle front to minimize the impact effect on a pedestrian when hit, — design provisions for the vehicle front for side (lateral) deflections in order to minimize the risk of being drawn under the vehicle on flat ground (embedded track), — design provisions for the vehicle body underframe to not aggravate injuries to a pedestrian/body lying on the ground, — provisions to prevent the pedestrian from being over-run by the leading wheels of the vehicle. This document focuses on the consequences of the primary and tertiary impact. The consequences of a secondary impact are out of the scope of this document. The following measures to actively improve safety are not in the scope of this document: — colour of front; — additional position lights; — additional cameras; — driver assistance systems; — additional acoustic warning devices, etc.; — view of the driver / mirrors; — consequences for pedestrian injuries due to secondary impact with infrastructure (side posts, concrete ground, poles, trees, etc.). The provisions of this document only apply to new vehicles. |
