Automated process for conducting crash simulations with varied occupants, occupant postures, safety technologies and crash
severities.
Professor raises concerns about safety equity
By JiNGWEN HU, Ph.D., associate director, research
associate professor and Miller Faculty Scholar,
University of Michigan Transportation Research
Institute. Read more about the author at the end of
this article.
Recent literature has shown that there is a growing
concern of safety equity in motor-vehicle crashes
(MVCs), but technological advances for addressing
this issue is still quite limited. Female, elderly and
obese occupants are among the vulnerable
populations who are often at increased risk of death
and serious injury compared with mid-size young
men in MVCs. Field data have shown that vehicle
airbag systems are less effective for smaller
occupants than those who are mid-sized. If the injury
risk for all ages were assumed to be the same as that
at age 20, 1.1-1.32 million fewer occupants would be
injured each year in the U.S., which is nearly half of
the total annual injury numbers in MVCs. Obese male
drivers have a significantly increased risk for death
due to MVCs, especially at high speeds. All the above
findings highlight the critical need for new

technologies that account for
human variability to protect
occupants more equally.
Causes of safety
equity issues
The inability of current vehicle
safety designs to deal with
human variation is a direct and
major contributor to the growing
concern of safety equity in our
society. The representation of
human variability in the safety
design process has been
severely limited due to the lack
of appropriate physical and
computational injury assessment
tools. Nearly all current vehicle
safety design optimizations use
crash test dummies, also known
as anthropomorphic test devices
