Multiple Impact car accident HVE Simulation - Coggle Diagram
Multiple Impact car accident HVE Simulation
Advantages
Different views allow for the user to understand all angles in the accident
Birds eye view
Level with road view
Individual Vehicle
First person/driver view
View of the passengers
Tyre marks
Allow the investigator to confirm the witness testimonies given by those involved
Allow the user to understand where the car decelerated or accelerated
Occupant Simulation
Allows the user to understand the damage to the occupants inside the vehicle up to four people
Allows the user to know where the passengers hit both the car and the other passengers
Allows the user to know which speeds are dangerous for passengers compared to others
Terrain mesh
Allows the user to mimic the exact terrain at the accident site
Able to understand exactly how the terrain had an impact on the events of the accident
Vehicle handing behaviour
Allows the user to understand how different vehicles handle in different climates
Takes into account the weather, downward or upward slope of the road, obstructions such as bridges, curves in the road
Multiple languages allow for a wider range of users
Add own measurements
Allows for the user to add their own measurements to be able to gain the most accurate recreation of the accident
Allows the user to add their own measurement whether it is imperial or metric
Allows for the user to include decimal places to ensure the information is the most accurate it can be
Database specific for different factors
Database that accurately represents the tyre information such as tread, width, etc.
Database that accurately represents different kinds of vehicles
Training provided for the use of the program
Costs begin at $500USD for 3 days of online training
Affordable compared to some other simulation tools available
Weather conditions
Allows the user to accurately represent the weather conditions that were occurring when the accident happened
How rain and snow impact the vehicle
Disadvantages
Basic animation
Only vehicle related accidents
Unable to investigate passenger-vehicle or object-vehicle accidents
Does not user Google Earth to get accurate map of accident area
Unable to choose the size, age, weight of the passengers
The age/ size/ weight of the passengers would have a significant impact on their injuries sustained and how much they move around in the car
Does not compile an acceration/ deceleration graph
Only a select amount of models that are based mainly on understanding single vehicle accidents
Unable to investigate multiple vehicle accidents to the extent of single vehicle accidents
Sunlight/ street lights/ car lights not taken into consideration of their impact on the outcome
User error in regard to the data collection
Cost
Unable to find any information on the cost of the program
Functionality

Tools used
Terrain Mesh
Allows the user to accurately represent the terrain in the accident location
GATB simulation programming
Allows the user to simulate the effects of the collision has on passengers
EDSMAC-4 programming
Allows the user to investigate multiple vehicle accidents
Basic data entry
Allows the user to include the data that they have collected from the accident site
