This technical report is applicable to tram vehicles according to ENΒ 17343 1. Tram-Train vehicles, on track machines, infrastructure inspection vehicles and road-rail machines according to ENΒ 173431 and demountable machines/machinery are not in the scope of this technical report.

This technical report 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 recommendations for the vehicle front to minimize the impact effect on a pedestrian when hit,

  • design recommendations for the vehicle front end for side (lateral) deflections in order to minimize the risk of being drawn under the vehicle on flat ground (embedded track),

  • design recommendations for the vehicle body underframe to not aggravate injuries to a pedestrian/body lying on the ground,

  • recommendations to prevent the pedestrian from being over-run by the leading wheels of the vehicle.

The following measures to actively improve safety are *not* in the scope of this technical report:

  • 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 recommendations of this technical report only apply to *new vehicles*.
