Road traffic accident statistics l.jpg

Road traffic accident statistics

  • Used for evaluating the level of road safety.

  • Provide guidelines for road safety measures and traffic planning.

  • The principal users of the statistics at the national level are Ministries as well as various central agencies and transport organisations.


Gis geographic information system l.jpg

GIS (Geographic Information System)

  • At the beginning of 2009, the police started to record accurate co-ordinates for accident scenes.

  • Statistics Finland introduced a new geographic information system to help locate the places where road traffic accidents occur.

  • The co-ordinates make it possible to combine road traffic accident data with geographical data Digiroad.


Digiroad l.jpg

Digiroad is a national road database.

Maintained and updated by the Finnish Transport Agency (formely the Finnish Road Administration).

Contains data on the locations of all roads and streets in Finland.

Contains information on geometry, physical features and travel-related characteristics.

The co-ordinate system of Digiroad is EUREF-FIN.

Digiroad


Combining digiroad and road traffic accident data l.jpg

Combining Digiroad and road traffic accident data

  • Statistics Finland receives from the police data on road traffic accidents.

  • After entering the data into the database, new accidents are located to the road network with the geographic information system.


The map application l.jpg

The map application

  • The map application can be used to correct the co-ordinates.

  • With the information from the police report one can relocate the accident on a map.

  • It is possible to make different inquiries about the roads and their features.

New information l.jpg

New information

  • Statistics Finland checks the information that the police has reported and supplements the data.

  • It is possible to get information about the accident that was not available before.

  • Locating the accidents on a map allows researchers to visualise the data better.


Conclusions l.jpg

Conclusions

  • A geographic information system allows us to handle, view, understand, interpret and visualise data in many new ways.

  • For the statistical process the geographic information system improves the quality of the data.

  • It is possible to get some missing information directly from the geographical data received.

  • The statistical process is more effective and the users have better quality and more information about road traffic accidents than before.
