Board Meeting Animations - Safety at Passive Grade Crossings Volume 1: Analysis

July 21, 1998

Animations

The following animations were presented at the Board meeting on July 21, 1998.

Animation #1
NTSB computer simulation illustrating how an approaching train appears to a motorist stopped at a grade crossing. Note that the farther away the train, the more slowly it appears to be moving. The train is moving at 40 mph.

Animation #2
NTSB computer simulation illustrating how an approaching train appears to a motorist who is approaching a grade crossing. Note that although both vehicles are moving, the image of the train stays in the same part of the motorist's visual field, and the only cue the driver has that the train is moving is the apparent growth in the size of the train's image. The farther away the train, the more slowly it appears to be moving. Both the train and the highway vehicle are moving at 40 mph.
