Dissemination of sporting events in the urban area

Abstract

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.
