Dissemination of sporting events in the urban area


  • Tejs Scharling Alexandra Instituttet




The city space is increasingly used for sports events. The city's geographical structure offers exciting opportunities, but also communication challenges. Limited visibility necessitates digital communication - precisely and in real time. The runners move freely between posts, bounded only by the geography of the city; houses, walls and fences. GPS measurements are disturbed by buildings and, if transmitted raw, it can give a misleading impression of the runner's actual route; across buildings and through walls. By combining geodata about the city with the progress of the route in a particle filter, the quality is significantly improved in real time. The runner sticks to obvious routes and possible areas. The particle filter is a flexible statistical machine learning technique that can also be used for e.g. drones and self-driving robots in urban space.
