Initiative details

In-depth accidents analysis is a unique research activity conducted by Transport Research Centre (CDV). Data from In-depth Accident Analysis provide a comprehensive view of all the factors related to a particular accident and serve to identify the characteristics leading to the crash occurrence and how they affect its consequences.
In – depth Road Accident Analysis includes following research areas:
-transport infrastructure,
-vehicle design and construction,
-human factor and psychology
-medical research.
Our activities are realized in long-term horizon and all the research is subjected to strict conditions, including personal data protection.

We conduct traffic accident research within the National Centre of Czech In-Depth Accidents Analysis (CzIDAS). One of its aims is cooperation with entities that could further use the results of research, for example road owners or administrators, vehicle designers and also researchers etc.
The CzIDAS data is used for various purposes and helps to face current road safety challenges:
- Due to its comprehensiveness, Czech in-depth crash analysis is one of the most effective tools for targeted and comprehensive decision-making on measures related to road safety and the establishment of the National Road Safety Strategy and other government documents related to road safety.
 CzIDAS is a source of unique information for targeting preventive information campaigns. The use of in-depth data allows us to influence road users using real crash scenarios with their consequences and highlights specific risky behavior.
 the database creates also a unique framework for a number of educational activities, e.g. Education on children's traffic behavior in the form of LARP, methodology for teachers of traffic education, Seniors in road traffic, e-TESTs and teaching and training methodology for the initial education of examiners and for subsequent periodic education of examiners,
 The activity contributes to the creation of safe road infrastructure (infrastructure adjustments based on the measures as a result of in-depth crash analysis).
 The project serves and has the potential to serve as a unique source of data and knowledge for further research in this area, including autonomous control systems. Data was used eg. for the development of a specific technical element of passive safety to protect the cervical spine, the development of an element of active vehicle safety to mitigate the effect of primary contact between pedestrian and vehicle, etc.).
 The data also serves fo validation of models used for accident analysis or creation of knowledge-based database for forensic experts,.
 Traffic crashes, however, result not only in physical but also the psychical health damage and serious social consequences. Every road traffic accident has the potential to be a traumatic event and may result in significant disruption to the psychological integrity of the people involved. The impact of a road traffic accident can adversely affect the quality of mental and physical health and subsequently interfere with many areas of one's social life. The contribution of the project could be seen also in psychological assistance to the traffic accident victims at the scene of the traffic accident.

Project activities

If you work together with external partners, list the most important partners and briefly describe their role.

In the course of the project solution, between 2015 and 2018, we collaborated with the Škoda Auto company. The Škoda Auto company used the results of the project for the design and modification of safety systems in the vehicle.
We also collaborated with University of West Bohemian – the University used the data for the validation of virtual human body model.
The accident database also serves as a basis for other research projects realised in cooperation with commercial and academic partners.

Please describe the project activities you carried/are carrying out and the time period over which these were implemented.

As part of the project, a traffic accident analysis is carried out directly at the scene of the traffic accident. The analysis of the accident is carried out from the point of view of the accident participants, the vehicle, and the transport infrastructure. A comprehensive analysis of each accident (including the movement of individual participants, the possibility of collision avoidance, etc.) is carried out and all contributory factors of a traffic accident are determined (of the whole system vehicle – human - infrastructure). On the basis of this data, measures are subsequently proposed to prevent a traffic accident, or at least to reduce the possible consequences. This entire cycle has been going on without a break since 2011 to the present.
The data is subsequently analyzed with regard to the purpose of further use - definition of KPI in the area of setting government strategies, education, accident prevention, automotive, etc.
The use of our data for communication and preventive activities allows to influence road users behavior using real crash scenarios in the context of its course and consequences and focused on critical aspects of road users behavior (specifically critical aspects which can not be identified using other daata sources - consequences of using non-homologated elements, bypassing security systems, consequences of non-standard seating positions during a collision etc.).
We use real accidents, real scenarios - the behavior of real people with real consequences, not just an impersonal simulation. And accident can happen to anyone, even on a short distance trip.... it may not even be his fault...
(see eg.


What has been the effect of the activities?

The number of people contacted is difficult to estimate. However, the impact of this activity is nationwide. The main effect consists of preventive action and elimination of risky behavior. It is also necessary to mention that we also point out behavior that road users often do not perceive as dangerous (mind-wandering, interaction with in-vehicle devices, carrying an unsecured load inside the vehicle, use of unsuitable child restraint systems)
The communication campaigns were addressed to the general public as well as to selected road users (eg. VRUs). Society, especially road users, is addressed via our website, Facebook, and YouTube channel. Furthermore, people are addressed through campaigns organized by the Ministry of Transport, for which we are preparing documents and thematic analyzes on traffic-safety topics (namely eg. campaigns Inattention kills, Limit – focused on the motorcycle riders, 30minutes – focused on speed).
The accident reduction is obvious on the adjusted accident locations (based on the measures resulting from in-depth accident analysis).

Please briefly explain why your initiative is a good example of improving road safety.

We find out what had an influence on the origin, course or consequence of the traffic accident. Based on this information, we are looking for a solution that will prevent the occurrence of a traffic accident, or at least reduce the negative consequences. We provide this information to the lay and professional public.

How have you shared information about your project and its results?

We published our results in professional journals, regularly present the results of our research at professional conferences on national and also international level, e.g. Expert Forensisc Science, Traffic Accidents, etc.
We provide our results to the Independent Road Safety Department, which further uses them for its press releases and communication campaigns. We also share information via the website and social networks.
