Charleston police upgrade forensic equipment

Posted: Updated:

The Charleston Police Department Traffic Division has recently upgraded its forensic mapping equipment and software. The equipment will be used to investigate the collisions of automobiles, motorcycles, bicycles and pedestrians that result in serious or fatal injuries.
 
Crash Reconstruction is a process that determines pre-impact, impact, post impact and area of impact circumstances from physical evidence at the scene. Examination of the scene is made and measurements (Forensic Mapping) are taken of the scene utilizing a Sokkia Total Station. All evidence at the scene is photographed and analyzed to assist in determining the cause of the crash.
         
Forensic Mapping is conducted by using the Total Station and storing the information on an Archer data collector. The data is then downloaded into a PC and imported into MapScenes crash software and diagramming programs to produce scale drawings of the scene.
 
A scale diagram, vehicle evidence and inspections, scene and roadway evidence and statements obtained through witness and occupant interviews are all used in reconstructing the crash. Formulas are used to calculate the speeds of the vehicles.
 
Crash Reconstruction is an essential tool for the Charleston Police Department to determine and identify causes of crashes that can later be used to educate the motoring public in an attempt to make the roadways of Charleston safer.
