1.6.1.6.2: Detect Imminent Vehicle/Train Collision

This process is responsible for detecting imminent collisions between vehicles and trains at railroad grade crossings. Using the data contained in the predicted_hri_state message this process performs the necessary calculations to determine whether a collision is imminent. If so, this process returns a hri_predicted_collision message to the "Close HRI on Detection" process.

This process is associated with the ITS Roadway Equipment physical object.

This process is associated with the following functional objects:

• Roadway Advanced Rail Crossing

This process is associated with the following data flows:

• hri_predicted_collision
• predicted_hri_state
