“V2X-based Collision Avoidance System for MTB Trail Riding,” Project or B.Sc./M.Sc. Thesis, F. Kargl (Supervisor), F. Kargl (Examiner), Inst. of Distr. Sys., Ulm Univ., 2023 – Open
The alps see a surge of trail parks being built. These trails include frequent turns and jumps which are often ridden at high speeds. If bikes block the trail due to a stop or accident, limited line-of-sight can lead to collisions and severe accidents when following bikes crash into the blocking bike. With this work, we want to investigate if V2X communication can provide blocked trail warnings to approaching bikes so that riders can reduce their speed and avoid accidents. For this, a number of technologies that have been developed for collision warning in automotive and street-based scenarios need to be investigated, adapted, and tested for suitability. This includes the V2X communication module and antenna, that need to be adjusted to fit into a bike. Communication ranges and reliability have to be tested in realistic outdoor settings. Second, it needs to be reliably determined whether a bike actually blocks a trail or whether the rider just stopped next to it. For this purpose, GPS accuracy alone is insufficient and might have to coupled with crash detection using motion sensors or camera-based image recognition to detect whether a bike blocks a trail or not. Last but not least, a suitable user interface has to be developed and tested that allows to warn approaching drivers in a reliable and intuitive way which works even during trail rides. The envisioned thesis or project can address one or multiple of these challenges, multiple students could also collaborate on the topic. The project is collaboration between Ulm University and University of Trento. After prototype development, field tests in the Alps in South Tyrolia / Alto Adige are planned.
