Vehicle Rail Crossing Warning

Overview

'Vehicle Rail Crossing Warning ' uses I2V communications to receive alerts of trains entering HRIs and to provide warnings to drivers regarding the trains. The warning can include second train warning (meaning the HRI gates are about to lower, or remain lowered due to the arrival of a second train). The application can also provide vehicle infringement warnings by using the alert information along with vehicle trajectory information to determine that the vehicle will infringe upon a crossing that is (or will be) occupied by a train.
