The value of simulations - Virtual Crash - Coggle Diagram
The value of simulations - Virtual Crash
limitations and weaknesses
the accuracy of the simulation relies not he accuracy of the information being put into it and the knowledge of the person putting it in.
the software is not easily used by anyone - requires more advanced mathematical knowledge and technological savvy to understand and utilise the features available
though the reconstructions are good to understand/visualise how an accident transpires, this is a very small part of an investigation
a lot of money and product expertise to operate and create, when it does not add to an accident investigations 'whys?' or 'lines of enquiry' - just visually depicts what is already known
this can confuse or distract from what needs to be done
This can also lead to bias as the conditions can be changed to suit the desired outcome
relies on scientific principles like acceleration and inertia which can be input as data - but how that affects a human body this cannot predict - unless that set of variables has been come across in an investigation.
practical testing and results is still often needed to prove or validate the resonstruction
simulations cannot capture all conditions
human/machine interface means there is always likelihood of machine/operator error - which can affect the integrity of the simulation
strengths
There is a range of variables that can be changed to suit the sitation, e.g. possibility of human models and vehicle characteristics can be altered
this allows for more realistic results
this allows to use in predicting something as well - e.g. good for traffic management and enacting policy and law
could be utilised in training and licensing as there are more variables that can be tested in a 'safe' way
can assist in creating safer vehicles for buyers, reducing manufacturer recalls and lawsuits etc
free trials and competitive/affordable pricing make it appear more accessible to more industries
Various industries which currently use the software, which shows versatility
comprehensive information and tutorial videos available
graphics are realistic
google maps interface which allows for realistic settings and terrain data for increased simulation/reconstruction accuracy
unusual or critical high risk variables can be assessed without posing harm / risk
shows pre and post impact geometry which accounts for some behavioural or situational variation on an accident scene
credibility and knowledge of authors
The website speaks briefly of its history
There is mention of computer scientists and engineers collaborating to create this software, but no information on credentials of these creators
The physics model has been reviewed in studies and held to a high acceptance
There is links to literature of scientific review and usability in a car crash reconstruction setting from Universities and various PhD authors adding to the credibility
