Abstract

An information sharing system derives from a roadway vehicles management system position-related data of a roadway vehicle along a road and determines a roadway vehicle timing at or during which the roadway vehicle is estimated to arrive at or cross a railway crossing. The information sharing system further derives from a railway vehicles management system position-related data of a railway vehicle along the railway and determines a railway vehicle timing at or during which the railway vehicle is estimated to arrive at or have passed the railway crossing. The information sharing system determines, based on comparing a roadway vehicle time window to a railway vehicle time window, that the roadway vehicle time window and the railway vehicle time window at least partly overlap. The information sharing system provides information associated with the overlap to the roadway vehicle or the railway vehicle.
