THE ROLLOVER PROPENSITY OF FIFTEEN-PASSENGER VANS

A question has been raised as to whether fifteen-passenger vans, especially loaded fifteen-passenger vans, are unusually susceptible to rollover. Fifteen-passenger vans differ from most light truck vehicles in that they have a large payload capacity and the occupants sit fairly high up in the vehicle. Therefore, when loaded the vehicle may have a much worse rollover propensity than when unloaded. To examine this issue, a brief study was performed in three parts: a review of crash data to look at the record of fifteen-passenger vans; measurement of the Static Stability Factors (SSF) of a fifteen-passenger van, a seven-passenger van, and a minivan; and a simulation analysis of the handling characteristics of an unloaded and loaded fifteen-passenger van. Results of this study are presented in this Research Note. It was concluded that fifteen-passenger vans might be more likely to roll over when fully loaded with occupants than when lightly loaded. Analysis considering the number of occupants in the vehicle showed that fifteen-passenger vans with ten or more occupants had three times the rollover ratio than those with fewer than ten occupants.
