To get high quality data, information and well-structured tools, for each road safety product, a methodology has been developed. You can find out more about it, by searching the product that you are interested in.
How to find the right methodology?
If you are interested in how the web texts (Knowledge part) are written, see Safety issues. For the methodology that has been followed to gather SPI's for instance, look for Data methodologies, and there the sub-part of SPI's.
Per road safety subject, a supervisor is appointed within the editorial group/board. Together with a writer, who may be part of the editorial group/ board, the supervisor is responsible for producing up to date and reliable information on that particular subject. The other editorial board members provide feedback on the texts. In the end, all editorial board members have to agree on the text, before it is put on the website.
Country products are based on statistical information. More information on how these statistics are collected, can be found under Statistics.
More background information on country overviews can be found here.
The country overviews have been made following a certain fixed structure and with data available. You can find more about background information here .
Methods for collecting statistics differ per item.
To get more information on methodological information on statistics, an example can be seen under meta-data.
You can find more information on design principals of basic facts sheets and the annual statistical report here
Using data for policymaking or in scientific research requires sufficient knowledge about the quality of the data source. Information that is relevant to assess the quality of data can be found here .
For the design of Basic Fact Sheets and the Annual Statistical Report, special design principals were defined, which can be found here .
The European Commission recognises the importance of in-depth road accident investigations to identify areas of priority and develop accident countermeasures. Currently only a small number of European countries systematically collect such data. By preparing a common methodology and data systems and by increasing the number of teams, the DaCoTA project aimed to contribute to improve road safety across Europe.
The DaCoTA team worked towards the long term vision of an on-going, pan European accident investigation activity. It aims at providing comprehensive in-depth data that will be collated into a large scale database. A database system and on-line manual have been readied and a network of investigators established across 19 countries in Europe and neighbouring regions.
The on-line manual covers the scope, characteristics and the practical requirements of the methodology. It also contains detailed information on variables (or data fields) in the DaCoTA in-depth database system.
