Database name:	Traffic Accident Information Database (TRAID)
Thematic Coverage:	This database collects information on motor vehicle accidents, including all fatal, personal injury and property damage collisions over $1000. Accidents involving pedestrians (only if a motor vehicle is involved) are also covered.
Maintained by:	Transport Canada
Availability:	Requests for extraction of raw data can be granted with approval from the jurisdictions for specific research projects. This database is not linked with external databases.

Start Date:	1984
Release Date:	Approximately 12 months after collection
Frequency of collection:	Annual

Data Collection:	Data complied from all provincial and territorial ministries of transportation from submitted police reports. Reporting forms are not uniform and some jurisdictions do not supply all the information regarding some of the variables in the database.
Sample size:	Approximately 600,000 collisions yearly

Geographic coverage:	All provinces and territories
Lowest geographic level collected:	Accident location; varies by province but name of street of accident (i.e. no intersection information available). In Ontario, B.C., Manitoba, New Brunswick and Nova Scotia, police detachment codes are reported to denote accident location.
Lowest geographic level of release:	Province; in order to use the data at smaller geographic levels, the data must be obtained from each province.
Existing rural variable:	Yes

Urban is defined as metropolitan roads, streets and other urban areas, or where a posted speed limit at the collision site is 60 km/h or less. Rural is defined as a primary or secondary highways and local roads or where a posted speed limit at the collision site exceeds 60 km/h.

Rural definitions that can be constructed from this database include (building block):

None of the rural definitions in Appendix A can be constructed from this database*

* In order to construct these definitions, the location of the accident would be required to be translated from police detachment codes to postal code.



Data Elements:

• Accident location and contributing factors
• Road classification
• Driver and passenger demographics
• Type of vehicles involved
• Severity of accident
  

Notes:
Due to the way "rural" is defined for this data source, a collision on the 401 going through Toronto would be coded as rural since the posted speed limit is 100 km/h, even though the collision occurred within the geographic boundaries of Toronto.

A decline in police reporting in British Columbia from 1996-2000 has affected the British Columbia totals and, to a lesser extent, national totals of the population.
