Railway applications - Vehicle end design for trams and light rail vehicles with respect to pedestrian safety

This technical report is applicable to tram vehicles according to EN 17343. Tram-Train vehicles, on track machines, infrastructure inspection vehicles and road-rail machines according to EN 17343 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.

Bahnanwendungen - Fahrzeugkopfgestaltung von Straßenbahnen und Light rail Fahrzeugen im Hinblick auf den Passantenschutz

Applications ferroviaires - Conception de l'extrémité des tramways et véhicules ferroviaires légers pour la sécurité des piétons

Le présent Rapport technique s'applique aux tramways selon l'EN 17343 . Les trams-trains, les engins de travaux sur voie, les véhicules d'inspection de l'infrastructure et les machines rail-route selon l'EN 173431, ainsi que les machines déraillables ne sont pas couverts par le présent Rapport technique.
Le présent Rapport technique décrit les mesures de sécurité passive en vue de réduire les conséquences des collisions avec les piétons. Ces mesures décrivent les moyens de protection de dernier recours lorsque toutes les possibilités de prévention d'accidents ont échoué, par exemple :
- des recommandations de conception pour l'avant du véhicule afin d'atténuer l'impact d'une collision sur le piéton ;
- des recommandations de conception pour l'avant du véhicule, concernant la déviation latérale afin de réduire le risque de projection du piéton sous le véhicule sur terrain plat (voie encastrée) ;
- des recommandations de conception pour le châssis du véhicule afin de ne pas aggraver les blessures d'un piéton/corps allongé sur le sol ;
- des recommandations afin d'éviter un écrasement du piéton sous les roues avant du véhicule.
Le présent Rapport technique ne traite pas des mesures d'amélioration de la sécurité active suivantes :
- couleur de l'avant du véhicule ;
- feux de position supplémentaires ;
- caméras supplémentaires ;
- systèmes d'assistance à la conduite ;
- systèmes d'avertissement sonore supplémentaires, etc. ;
- visibilité du conducteur/rétroviseurs ;
- blessures liées à un impact secondaire avec l'infrastructure (poteaux latéraux, sol en béton, arbres, etc.).
Les recommandations du présent Rapport technique s'appliquent exclusivement aux véhicules neufs.

Železniške naprave - Zunanja konstrukcija tramvajskih in lahkih železniških vozil glede na varnost pešcev

Ta dokument se uporablja za tramvajska vozila v skladu s standardom prEN 17343. Tramvajska vozila, tirni stroji, vozila za pregledovanje infrastrukture in cestna železniška vozila v skladu s standardom prEN 17343 ter demontažni stroji/ustroji ne spadajo na področje uporabe tega tehničnega poročila.
Ta dokument opisuje pasivne varnostne ukrepe za zmanjšanje posledic trkov s pešci. Ti ukrepi zagotavljajo zadnje sredstvo za zaščito, kadar vse druge možnosti preprečevanja nesreče niso uspele, t.j.:
– oblikovalska priporočila za prednji del vozila, s katerimi se zmanjša vpliv na pešca ob trku;
– oblikovalska priporočila za prednji del vozila za bočne (lateralne) odklone, s katerimi se zmanjša tveganje, da bi pešca na ravnem terenu (vdelana proga) potegnilo pod vozilo;
– oblikovalska priporočila za podvozje karoserije vozila, s katerimi se prepreči dodatno poškodovanje pešca/telesa, ki leži na tleh;
– priporočila za oblikovanje, s katerimi se prepreči, da bi vodilna kolesa vozila povozila pešca.
Naslednji ukrepi za aktivno izboljšanje varnosti niso zajeti v tem dokumentu:
– barva prednjega dela vozila;
– dodatne pozicijske luči;
– dodatne kamere;
– sistemi za pomoč voznikom;
– dodatne zvočne opozorilne naprave itd.;
– pogled voznika/zrcal;
– posledice za poškodbe pešcev zaradi sekundarnega trka z infrastrukturo (stranski stebri, betonska tla, drogovi, drevesa itd.).
Priporočila tega dokumenta veljajo samo za nova vozila.
