Innovative Solutions for the Reconstruction, Investigation and Cause Analysis of Traffic Accidents: the Project
Analist Group has long studied the applications that can be of undoubted use for the community (public and not) in those key areas where the old and traditional methods appear, at present, overcome by new technologies on the market. One of the areas on which we have focused our attention on has been the reconstruction, cause analysis and investigation of traffic accidents. Phenomenon quite common, which are faced by large human resources as well as technical resources. The deepening of the issue is the result of a series of informal meetings with the operators in this field such as local police forces to which we have turned to better understand what the methods and instrumentation used for the recontsruction of said events are and how to devise the best system to implement with state of the art technology.
Traditional Accident Reconstruction and Investigation Method
Police Forces use their consolidated car accident reconstruction and investigation methods with triangulations and parallel lines generating a sketch which they subsequently scale (1:100; 1:200.).
The completion of these operations lies on the undisputed professionalism of the officers, who use the following tools:
a) a 20m distance metre;
b) a note pad for the sketch;
c) a pencil;
d) chalk;
e) a camera..
Conventional Techiques and Tools determine risks and issues, among the most common:
1. a long period of time to carry out the operations, which cannot always be quantified, and which most of the time, causes a total or partial closure of the accident area;
2. high danger risk for the officers involved in the reconstruction (normally two), with different tasks: one directs the traffic and the other carries out the reconstruction and survey operations;
3. high danger risk for people involved and motorists in the accident area.
New Reconstruction and measurement Techniques
Today innovative technological resources can be implemented to replace (or supplement) the more tradtional methods. These resources can ensure a highly improved result, which will be satisfying the needs of the community. All this in full agreement with the new code of crimanal procedure which is based on the acquisition of criminal evidence, abandoning the old inquisitive system.
This to say that in the reconstruction of an accident, or at least in the initial phase (which is the most delicate) should be carried out with approved instrumentation and equipment with an objective output.
Benefits of New Technologies
The newest technologies, DRONES equipped with with a camera and the use of a reconstruction software allow: • Reconstruction and documentation of the accident, with contextual acquisition of photogrammetric data in just a few minutes; • Error margin equivqlent to zero; • Reduction safety risk of police officers as well as motorists; • Re-opening of roads and motorways to traffic in very few minutes.
