Atlanta Engineering Services, Inc. offers scene mapping and land surveying services to document and gather evidence at the scene of an accident. Scene mapping is the process of taking measurements, collecting data and illustrating evidence on a scaled drawing of the roadway. Drafting personnel prepare the drawings using Computer Aided Design (CAD) programs, such as AutoCAD.
Accident scene diagrams provide the engineers with an overall view of where evidence is located in the roadway in order to reconstruct the accident. In accident reconstruction, the following must occur regarding matching the simulated path of vehicles with scene evidence:
Scene mapping depends on the type of accident that is being mapped, whether there are any roadway defects, roadway design flaws and roadway maintenance issues.
Hydroplaning accidents are one example in which these situations come into play. The geometry of the roadway is of particular concern. The roadway is surveyed and elevation data collected to prepare a topographic survey showing the slope of the roadway, drainage patterns, and existing stormwater systems.
The engineer analyzes the scene map to determine whether hydroplaning contributed to the cause of the accident.
Scene maps are also used to create surface models for 3-D Accident Simulation Videos.
Creating simulations is an iterative process in which multiple simulations are ran until the simulated path of vehicles corresponds with scene evidence, vehicle crush damage and other evidence. Using a site specific roadway environment in a simulation is critical in creating an accurate simulation, making scene maps ever so important.
Below is a sample scene map that was put together for a two car accident where a 2009 Honda Accord failed to yield the right-of-way when making a left turn.
