Bus Accident

Foxboro Stadium, Boston, MA

Background: A bus used to transport patrons who were utilizing parking facilities at Foxboro Stadium to attend a local golf tournament was struck by a large gate. The gate was unintentionally left unlatched, swung into the path of the bus during a wind gust and penetrated the bus interior, injuring numerous passengers and destroying the bus.

What We Did: In reconstructing the accident, the bus speed was analyzed and determined from on-board data acquisition systems, consistent with witness testimony. The aerodynamic properties of the gate and local weather data were used to compute the rate at which the gate swung into the path of the bus. Finally, a scale model was built as a demonstrative aid for Jurors. Calculations showed that given the standard perception/reaction time used in accident reconstruction, the bus driver could not have reacted in time to avoid colliding with the gate.
