I attended the AAAM annual conference, held in Madrid. (Thanks to Dr. Fran Lopez-Valdez and our excellent hosts at Comillas Pontifical University!) I presented an overview of recent work we did looking at front-seat passenger responses to abrupt vehicle maneuvers. This work, which was also published in Traffic Injury Prevention, compared head excursions in braking and lane change across three vehicles. We found unexpectedly small forward excursions in braking in one vehicle, but overall the differences were small compared to intersubject variability that is not explained by passenger characteristics. We are continuing this work with a large-scale study of 90 men and women with a large range of initial postures and positions.
