| Fixed Object Traffic Accident Reconstruction Expert |
Providing Quality Accident Reconstruction and Investigation
| Each year, approximately 160,000 people are involved in side impacts with fixed roadside objects. - NHTSA |
In the United States, collisions with fixed objects and non-collisions account
for only about 19% of all reported crashes, yet they result in 44% of all
fatalities.
Accident reconstruction data reveals that trees and utility poles are by far
the most frequently struck objects. A collision with one of these two fixed
objects results in the highest risk of injury and, therefore, are the objects
causing the greatest loss to society.
Experts estimate that accidents involving fixed objects represent a loss to
our society of about $3 billion each year.
And while the type of object that is struck often predicts the severity of
subsequent injuries, there are other variables which can affect the
outcome of a fixed object crash, which include driver characteristics, such
as size or age of the driver.
Certain types of traffic violations are also strongly associated with fixed
object crashes.
For example, driving over the speed limit and driving under the influence
of alcohol increase the probability of being in a fatal fixed object accident.
And, not surprisingly, drivers that do not use seatbelts are associated with
an increase in the probability of more severe injuries, even when an airbag
is deployed.
When a vehicle strikes a fixed object, some of its kinetic energy (energy
due to motion) is converted into work, or in this case, vehicle deformation
and fixed object damage.
Our accident reconstruction experts employ a variety of investigative
measures, including energy analysis, to explore, determine and evaluate
the events leading up to a fixed object crash.

Vehicle type and maximum crush depth can be used by experts to
estimate a vehicle's barrier equivalent velocity via empirically derived
accident reconstruction formulas, such as Victor Craig's narrow object
crush equation.

Scene evidence, such as skid marks or yaw marks are often an
intricate part of determining the pre-impact motion of a vehicle before a
fixed object collision.
