Strengths of the tool
Uses accurate maps
Accurately inputs data
Allows the virtual accident to represent closely what has occurred on the accident site
Lighting
Changes can be made to the light whether it be from sunlight or from street lights and car lights
Sunlight can be included showing where it would have hit the vehicle/ person dependign on the time of day and how that would have affected the final outcome
Street lighting and other vehicle lighting can also be included to show how this would have distracted/ had an impact on the final event
Maps exact path
the program maps the exact path of the accident so investigators are able to know when the impact occurred and what happened directly before and after the impact
Interaction with still objects
User is able to include any obstructions that were factors in causing the accident
Allows for a wider range of accidents to be replicated not only ones with multiple vehicles or people and vehicles
Tyre marks
Allows the user to understand where tyre marks would have been made through the sharp deceleration or acceleration of the vehicle
Allows the investigator to verify the stories provided by those involved to ensure they have the correct information
Terrain
Allows the user to mimic the terrain of the accident exactly how it is in real life
This allows the virtual accident to mimic what would have occurred
it provides the investigators the ability to understand exactly how the accident occurred
Impact marks of other objects/ people
Allows the investigator to verify the story of those involved
Allows the investigator to know exactly where the impact occurred
Speed Acceleration and deceleration points
Allows the user to know exactly where deceleration and accerlation occurred in the accident and how that impact the final results
This is also marked on the program by graphing it to using green, orange and red colours to know exactly where the acceleration, maintain speed, and deceleration occurred
Tools used to create program
Google Earth
Allows the user to insert the exact location of the accident area
Data input capabilities
Allows the user to include a range of information such as
Speed of vehicle
Weight of vehicle
Time accident occurred
Acceleration and deceleration rate
Acceleration path segments
RTK GPS measurements
Real Time Kinematic positioning allows the use of satellite navigating techniques to enhance the precision of position data
360 degree viewing
allows the user to use 360 goggles to view the crash in "real time"
Ability to look at the crash in a 360 degree format from any point in the recreation
third party terrain mesh
Includes rivers, rises and drops in road, mountains, overpasses, etc.
third party vehicle mesh
Allows the user to mimic the vehicle/s involved in the car accident
Different angles
Allows the user to watch the accident from aerial view as well as side view and first person
Orthographic views
Limitations of tool
Data must be accurate to ensure the program is accurate
Relies solely on the other equipment used in the field to have accuracy in the data collected
Also relies on the correct data being collected by investigators so the data used by the system needs to be known in advance
Relies on the accuracy of investigators
User error
If the investigators are incorrect in the information collected or provided then the programming for the accident will be incorrect
Cost and availability to users
Different costs for the different version of the VC program (there are currently five different versions)
Free program available however not nearly as advances as the other programs that cost money
Full software package is around $20,200 + License key which is an additional $4,000
A wide range in the cost of the program depending on the software level
An added cost in the training of people to use the program
Only road and land accidents
No option for sea or airplane accidents limiting the accidents that can be recreated by the user
Generalised accident information
Unable to mimic where the driver was paying attention
Unable to mimic other factors such as:
Sleep deprivation
Intoxication
Distractions from other passengers
Phone or other technological distractions
unable to track exactly where a body or vehicle will land due to the accident factors being rigid
Unable to track where each parts of a body will land if it is separated
Unable to track where different parts of the vehicle may land if they become detached
Functionality
Legal uses
recreate accidents for caught cases
able to find responsibility in multi-vehicle accident
Insurance reasons
Forensic investigation
able to recreate accidents from years ago
Able to recreate accidents and include different factors to understand
Data analysis
From accidents that occur in certain areas or on certain roads
Different vehicle accidents
Simulate multi-vehicle / pedestrian accidents
vehicle safety
Able to create scenarios to ensure their vehicles will meet standards
Able to see the different ways different vehicle bodies will react
Road design
how different curves in the road will affect vehicles
Able to know what speed signs are best suited for works
Where signs should be placed on the road such as "give way" and "stop"
