The Canadian approach and experience in using IRTAD for national road safety policy formulation.

The roles of the Canadian federal, provincial and territorial organisations in administrating transportation safety programmes are outlined. Data are used to improve communication, co-operation and collaboration among road safety practitioners and raise the effectiveness of public education. The database is also used to improve the accuracy, standardisation, collection and dissemination of collision data, improve the funding of safety programmes and increase enforcement. The existence of IRTAD has helped to expose the lack of comparable information in Canada, particularly vehicle kilometrage data. Data from IRTAD are also used to supplement Canada's T-Facts database.
