Haddon provided much more elaboration, though, to the role of injury
intervention programs. Drawing from the Haddon Matrix and considering
that the primary agent involved in injuries from motor vehicle accidents
was the transfer of physical energy, Haddon proposed 10 steps to reduce
the impact of this physical energy transfer, and thus, reduce injuries.
These steps are outlined here. They focus primarily on altering the
environment in which the energy transfer takes place and the degree to
which energy can be built up.
For example, speed limits aid in reducing the degree of energy that can
potentially be involved in a crash. Engineering designs and changes in
the automobile can affect the time and space is which energy transfer
takes place. Overall, these principles transformed injury control
efforts.
