Future Position Prediction and Uncertainty Estimation for Vehicles and Bicycles via Integration of In-vehicle and Base Station Observations
Hayato Tsuji, Yuichi Ohsita, Hideyuki Shimonishi (UOsaka) IN2026-1
Abstract (in Japanese) (See Japanese page) 
(in English) Cooperative perception via V2X communication can complement surrounding traffic information that is difficult to observe from a single vehicle, but unobserved areas remain when traffic density or the number of sharing vehicles is low. Wide-area sensing by base stations can potentially compensate for such missing observations, although its sensing quality may vary. In this paper, we propose a method that integrates in-vehicle and base-station observations to jointly estimate future existence probability and cell-wise prediction confidence under incomplete and uncertain observation conditions. Experimental analysis shows that the estimated confidence correlates with prediction correctness for cells predicted as negative. On the other hand, simple threshold-based use of confidence provides only limited improvement, suggesting that additional design is required for effective utilization.
