Les accidents de la route ont des cons\u00e9quences dramatiques pour les individus, leurs familles et les nations, causant chaque jour plus de 3\u00a0000 d\u00e9c\u00e8s et repr\u00e9sentant en moyenne 31\u00a0080 milliards de dollars du PIB mondial. En identifiant et en priorisant les am\u00e9liorations d'infrastructures, les autorit\u00e9s routi\u00e8res peuvent rendre le r\u00e9seau plus s\u00fbr pour tous les usagers. Voici comment les donn\u00e9es de cartographie mobile de TomTom (MoMa) contribuent \u00e0 simplifier ce processus.<\/p>\n

Avec le d\u00e9veloppement croissant du monde, le nombre de routes construites et de voyageurs augmente. Si cela favorise la mobilit\u00e9 et la croissance \u00e9conomique, un r\u00e9seau routier plus \u00e9tendu et plus fr\u00e9quent\u00e9 soul\u00e8ve de graves probl\u00e8mes de s\u00e9curit\u00e9. Chaque ann\u00e9e, environ 1,3 million de personnes perdent la vie dans des accidents de la route, selon l'Organisation mondiale de la Sant\u00e9. Un nombre encore plus important \u2013 entre 20 et 50 millions \u2013 sont bless\u00e9s, m\u00eame l\u00e9g\u00e8rement, dans des accidents de la route. (Des chiffres plus d\u00e9taill\u00e9s sont disponibles sur le site Vaccines for Roads.) Pour rem\u00e9dier \u00e0 ce probl\u00e8me, l'Assembl\u00e9e g\u00e9n\u00e9rale des Nations Unies s'est fix\u00e9 un objectif ambitieux\u00a0: r\u00e9duire de moiti\u00e9 le nombre de d\u00e9c\u00e8s et de bless\u00e9s dus aux accidents de la route dans le monde d'ici \u00e0 2030.<\/p>\n

\u00c0 la conqu\u00eate des \u00e9toiles<\/strong><\/p>\n

Pour atteindre cet objectif, les \u00c9tats membres de l'ONU se sont mis d'accord sur 12 objectifs mondiaux pour la s\u00e9curit\u00e9 routi\u00e8re<\/a>, notamment en veillant \u00e0 ce que toutes les nouvelles routes soient construites selon une norme trois \u00e9toiles ou sup\u00e9rieure (ou respectent les normes techniques pour tous les usagers de la route qui tiennent compte de la s\u00e9curit\u00e9 routi\u00e8re). Autre exemple, Cible 4<\/a>, indique que d'ici 2030, plus de 751 TP8 000 d\u00e9placements se feront sur des routes r\u00e9pondant aux normes techniques pour tous les usagers de la route qui tiennent compte de la s\u00e9curit\u00e9 routi\u00e8re.<\/p>\n

\u00c9tabli par l'organisme sans but lucratif International Road Assessment Programme (iRAP), le syst\u00e8me d'\u00e9toiles offre une mesure objective du niveau de s\u00e9curit\u00e9 intrins\u00e8que des routes pour les automobilistes, les motocyclistes, les cyclistes et les pi\u00e9tons. Plus le nombre d'\u00e9toiles est \u00e9lev\u00e9 (sur une \u00e9chelle de un \u00e0 cinq), plus la route est s\u00fbre.<\/p>\n

Le classement d'une route par \u00e9toiles d\u00e9pend de divers facteurs li\u00e9s \u00e0 sa nature. Par exemple, une route quatre \u00e9toiles est g\u00e9n\u00e9ralement \u00e9quip\u00e9e de glissi\u00e8res de s\u00e9curit\u00e9 lat\u00e9rales et d'un terre-plein central, et comporte des \u00e9changeurs avec des bretelles d'acc\u00e8s de type autorouti\u00e8re. \u00c0 l'inverse, les routes mal class\u00e9es pr\u00e9sentent souvent des obstacles fixes dangereux \u00e0 proximit\u00e9, de nombreux carrefours et aucune protection frontale contre la circulation venant en sens inverse, comme une glissi\u00e8re centrale.<\/p>\n

Selon iRAP<\/a>, le risque de d\u00e9c\u00e8s ou de blessure grave d'une personne est r\u00e9duit de 50% avec chaque am\u00e9lioration de la cote d'\u00e9toiles d'une route \u2013 ce qui en fait un outil pr\u00e9cieux pour mesurer et interpr\u00e9ter la s\u00e9curit\u00e9 routi\u00e8re.<\/p>\n

Donn\u00e9es en mouvement<\/strong><\/p>\n

En d\u00e9terminant le nombre d'\u00e9toiles attribu\u00e9es aux routes de leur r\u00e9seau, les autorit\u00e9s routi\u00e8res savent o\u00f9 prendre des mesures concr\u00e8tes pour am\u00e9liorer \u00e0 la fois la qualit\u00e9 et la s\u00e9curit\u00e9 des routes.<\/p>\n

TomTom<\/a> TomTom fournit des donn\u00e9es cartographiques et des services de haute qualit\u00e9 et coh\u00e9rents \u00e0 l'\u00e9chelle mondiale pour faciliter la mod\u00e9lisation iRAP, permettant ainsi aux gestionnaires de voirie d'\u00e9valuer et d'am\u00e9liorer la s\u00e9curit\u00e9 de leur r\u00e9seau. L'un des piliers de l'approche de TomTom est MoMa, une technique de collecte d'informations g\u00e9ographiques r\u00e9elles.<\/p>\n

\"TomTom2\"<\/p>\n

Les voitures TomTom MoMA ont r\u00e9cemment f\u00eat\u00e9 leurs 20 ans. Elles cartographient les routes du monde depuis plus longtemps que quiconque.<\/em><\/p>\n

Les v\u00e9hicules TomTom MoMa sont \u00e9quip\u00e9s des derni\u00e8res cam\u00e9ras 360\u00b0 \u201c\u00a0Ladybug\u00a0\u201d et du LiDAR \u201c\u00a0Velodyne\u00a0\u201d. Ces capteurs, associ\u00e9s au DGPS (GPS diff\u00e9rentiel), collectent plus de 700\u00a0000 points de donn\u00e9es avec une pr\u00e9cision de deux centim\u00e8tres. Pour chaque kilom\u00e8tre parcouru, un v\u00e9hicule MoMa capture environ 3,8 milliards de pixels, ce qui permet d\u2019obtenir des images de haute qualit\u00e9.<\/p>\n

Accr\u00e9ditation iRAP<\/strong><\/p>\n

Les donn\u00e9es TomTom MoMa sont d\u00e9sormais associ\u00e9es \u00e0 des outils logiciels garantissant un codage de haute qualit\u00e9 des attributs iRAP. Enti\u00e8rement accr\u00e9dit\u00e9e par iRAP, cette approche permet aux \u00e9quipes de codage d'enregistrer efficacement les attributs routiers gr\u00e2ce \u00e0 la technologie MoMa de TomTom. Ceci ouvre la voie \u00e0 l'utilisation des millions de kilom\u00e8tres de donn\u00e9es TomTom existantes pour les \u00e9valuations iRAP.<\/p>\n

Des informations riches r\u00e9v\u00e8lent de nouvelles perspectives<\/strong><\/p>\n

TomTom stocke les donn\u00e9es recueillies par ses v\u00e9hicules MoMa dans une immense base de donn\u00e9es contenant des millions de kilom\u00e8tres de donn\u00e9es routi\u00e8res. Ce pr\u00e9cieux ensemble d'informations est propos\u00e9 aux clients sous licence via le service MoMa de TomTom.<\/p>\n

Les images et les donn\u00e9es LiDAR (nuage de points 3D) du MoMA sont con\u00e7ues pour une int\u00e9gration ais\u00e9e avec les outils de gestion et d'analyse d'actifs. Presque tous les \u00e9l\u00e9ments captur\u00e9s dans une image ou un nuage de points peuvent \u00eatre extraits pour analyse, qu'il s'agisse de la signalisation routi\u00e8re, du mobilier urbain (\u00e9clairage, abribus et barri\u00e8res), du marquage routier ou des types de ponts.<\/p>\n

En utilisant des images de cartographie mobile, iRAP peut mieux comprendre la qualit\u00e9 des routes et signaler aux autorit\u00e9s les endroits o\u00f9 les infrastructures peuvent \u00eatre am\u00e9lior\u00e9es.<\/p>\n

Le potentiel des donn\u00e9es des sondes GPS pour atteindre les objectifs de l'ONU<\/strong><\/p>\n

TomTom continue d'enrichir MoMa as a Service afin d'aider ses clients \u00e0 tirer pleinement parti de nos informations de g\u00e9olocalisation. Cela inclut une nouvelle approche de collecte de donn\u00e9es, qui consiste \u00e0 agr\u00e9ger et analyser les donn\u00e9es GPS de notre r\u00e9seau de plus de 600 millions d'appareils connect\u00e9s pour identifier les axes routiers les plus fr\u00e9quent\u00e9s au monde. Gr\u00e2ce \u00e0 ces informations sur le trafic, les clients peuvent identifier les zones les plus congestionn\u00e9es de leur r\u00e9seau, ainsi que les points noirs potentiels d'accidents, et prendre des mesures cibl\u00e9es pour r\u00e9duire les embouteillages et am\u00e9liorer la s\u00e9curit\u00e9.<\/p>\n

Contribuer concr\u00e8tement \u00e0 la s\u00e9curit\u00e9 routi\u00e8re<\/strong><\/p>\n

Aujourd'hui, les donn\u00e9es TomTom MoMa permettent aux organismes d'extraire diff\u00e9rents types de caract\u00e9ristiques routi\u00e8res et d'effectuer des mesures de qualit\u00e9. Elles donnent aux gestionnaires de voirie les moyens d'inspecter, de g\u00e9rer et d'am\u00e9liorer la qualit\u00e9 \u2013 et donc la s\u00e9curit\u00e9 \u2013 de leurs routes.<\/p>\n

Les donn\u00e9es de TomTom compl\u00e8tent efficacement les \u00e9tudes traditionnelles du r\u00e9seau routier, offrant aux organisations un moyen rapide et \u00e9conomique d'identifier les attributs iRAP et de tirer parti de l'utilisation int\u00e9gr\u00e9e des donn\u00e9es LiDAR et d'imagerie pour d\u00e9terminer avec pr\u00e9cision le classement par \u00e9toiles des routes. Gr\u00e2ce \u00e0 la richesse des donn\u00e9es cartographiques et \u00e0 l'expertise de TomTom disponibles en tant que service, les clients acc\u00e8dent directement aux informations n\u00e9cessaires pour \u00e9valuer et am\u00e9liorer la s\u00e9curit\u00e9 routi\u00e8re sans investissement initial important.<\/p>\n

TomTom est \u00e9galement un partenaire actif de Innovations AiRAP<\/a>, qui explorent des moyens de permettre aux agences routi\u00e8res de b\u00e9n\u00e9ficier de donn\u00e9es RAP acc\u00e9l\u00e9r\u00e9es et intelligentes gr\u00e2ce \u00e0 l'intelligence artificielle et \u00e0 l'apprentissage automatique.<\/p>","protected":false},"excerpt":{"rendered":"
