Severity indexes for roadside objects
FM Council, JR Stewart - Transportation Research Record, 1996 - journals.sagepub.com
An attempt was made to develop severity indexes (SIs) for various fixed objects that are
struck when vehicles leave the roadway. The objectives of the study included both the
development of new indexes with recent data from two states and the exploration of
methodological issues related to statistical modeling and unreported crashes. Both severe
injury and cost-based SIs were developed for a wide range of crash situations by using data
from both North Carolina and Illinois with which injury could be more precisely linked to the …

Effects of air bags on severity indexes for roadside objects
FM Council, YM Mohamedshah… - Transportation …, 1997 - journals.sagepub.com
The effects of vehicle air bags on the severity of off-road, fixed-object crashes as indicated
by the effect that the air bag has on severity indexes (SIs) for fixed objects were studied. In
an earlier study, preliminary indications based on data from one state were that the
presence of an air bag might reduce SIs for various fixed objects by 35 to 75 percent. This
study extends that work by adding data from two other states and from additional crash
years. Severe-injury SIs were developed for different roadside objects for two samples of …
