Accident Database System (ADS)

 
Abstract:
The Ministry of Transportation of Ontario (MTO) maintains a database on every reportable motor vehicle collision that occurs in Ontario. The data are based on the motor vehicle accident report completed by the investigating police officer or staff at a Collision Reporting Centre. The Road Safety Program Office within the Road User Safety Division of the Ministry of Transportation Ontario (MTO), maintains the Accident Data System (ADS). This database was established in 1957, with a newer, more complete database beginning in 1988.

The data are used for: policy and program analysis, road safety research, marketing and performance measurement, and to promote safety on Ontario's highways by researching, planning, developing and evaluating road user safety initiatives directed at drivers of vehicles and other road users.

Collision data are provided geographically by place of occurrence, not by the residence of the driver or injured person; however, the driver's Forward Sortation Area or FSA (first 3 characters of postal code) was made available for some years (1995, 1996). Residence was obtained by linking the drivers’ license file with the collision file and is based on the drivers’ place of residence on one selected day during the year. Analysis based on place of occurrence can be misleading since collisions may occur to people who do not live in that area, particularly if the area is frequented by tourists and commuters.

Accident Database System ADS
The Ministry of Transportation of Ontario (MTO) maintains a database on every reportable motor vehicle collision (including farm tractors and snowmobiles) that occurs in Ontario. The data are based on the motor vehicle accident report completed by the investigating police officer or staff at a Collision Reporting Centre.

Frequency of Data Collection:
Annually
Sampling Procedure:
The data are based on the motor vehicle accident report completed by the investigating police officer or staff at a Collision Reporting Centre. Primary data are collected by police who fill in the Collision Report form at the scene of an accident. The form is sent to the MTO to be coded in to the ADS. If a victim dies within thirty days of the collision, the ADS is updated to reflect the fatality. Fatality data are collected and reviewed with the Chief Coroner's Office.

Characteristics of Data Collection Situation:
The data are available within about a year of the accident.

Notes & comments:
Data concerning fatalities are entered approximately ten days after the accident, while others take longer to be entered.

Approximately four to five hundred thousand records are added to the database annually. This includes one entry for each person involved in a collision. By 2003, there were approximately 6 million, seven hundred fifty thousand entries in the database.
Limitations:
MTO definitions and boundaries of Ontario counties and municipalities may differ from those of the Ontario Ministry of Health and Statistics Canada.

Analysis based on place of occurrence can be misleading since collisions may occur to people who do not live in that area, particularly if the area is frequented by tourists and commuters. Although there are approximately 20 different vehicle categories, there are no separate categories for either sports utility vehicles or taxis. They are both categorized under passenger vehicles, and therefore individual studies cannot be done on them. The identification of the type of animal, such as a deer or moose, involved in a collision, is not reflected in the database. The process of including more detail on the collision report is being implemented.

  • Analysis based on place of occurrence can be misleading since collisions may occur to people who do not live in that area, particularly if the area is frequented by tourists and commuters.

  • Drinking-related injuries and deaths may be underestimated due to drivers leaving the scene of the accident (hit and run).

  • Deaths and injury severity may be underestimated. Deaths occurring more than 30 days after the crash as a result of injuries suffered will not be recorded on the file. Underestimation can also happen for deaths within 30 days if proper follow-up is not done. Similarly, a person who does not go to hospital when leaving the scene of the crash may go at a later time to the emergency room or to be admitted. A person who goes initially only to the emergency room may return later and be admitted. These details may not be captured on the file.

Highlights
The database is successful in identifying trends related to motor vehicle collisions and then implementing safety measures in response to these trends. For example, it has identified a 36% reduction in the number of collisions caused by teen drivers since the introduction of graduated licensing.
Users and uses
The database is used in identifying trends related to motor vehicle collisions and then implementing safety measures in response to these trends.
Data Descriptions
Three groupings of files are on the database: collision information (e.g., location, number of vehicles involved, road conditions), driver/vehicle information (e.g., driver’s age and condition, vehicle type), and if a collision results in injury, information about the persons involved (age, sex, position in the vehicle). The files are linked by a common identification number.

Collision data are provided geographically by place of occurrence, not by the residence of the driver or injured person; however, the driver's Forward Sortation Area or FSA (first 3 characters of postal code) was made available for some years (1995, 1996). Residence was obtained by linking the drivers’ license file with the collision file and is based on the drivers’ place of residence on one selected day during the year. Analysis based on place of occurrence can be misleading since collisions may occur to people who do not live in that area, particularly if the area is frequented by tourists and commuters.

Core Health Indicators (Association of Public Health Epidemiologists - APHEO)
This website contains definitions (but not data) for over 120 public health indicators. Public health epidemiologists in Ontario collaborated with various partners to collate extensive information on each indicator. The result is a resource that enhances accurate and standardized reporting of information across public health units in Ontario. The Core Indicators were originally created to link to objectives outlined in the Ontario Ministry of Health and Long-Term Care’s Mandatory Health Programs and Services Guidelines. They are now being revised to reflect the Ontario Public Health Standards released in November 2008. The Core Indicators form the foundation for community health status reporting in public health in Ontario.

In some cases it is difficult to locate complete information to describe population health databases. When information was not available, this has been noted. If you have additional information to add to add to OPHID, we encourage you to contact us at ophid-help@scholarsportal.info
