Traffic Accident System Tool - BC Injury Research and Prevention Unit

Traffic Accident System Tool


UPDATE: Includes data up to and including 2019.

How to Use the Tool

The main data selection page displays the data in 4 main sections. Each section is further divided into topic areas which allow the user to select the information needed. The tool has been developed to allow easy navigation and minimal screen consumption. Therefore, all the parameters are stored under collapsible categories that expand when selected.

There are two main levels to the data presented. The first level is an aggregated version where data is presented as a group. The second level is more detailed and further breaks down the first level. The second level can be accessed by clicking on the arrow button beside the text.

Please note that the output tables will only display the data for those boxes that have been checked. As a default, we have thus ensured that all the boxes are checked in all the sections.

By selecting specific parameters in the search selection, outputs in the form of tables and charts will be generated. When clicking on the “new query” button, your original selections will remain checked to avoid any duplication of steps. Please ensure that you clear any previous selections, if different from your new query. If the “reset” button is clicked, the page will default back to the original page where all the selections are checked. A summary of your selected parameters as well as the date and time of your search will appear before each outputted table and chart to allow you to cross reference your selections.

Please note that the output produced will only display 2 options at a time. Below is an example that may assist you with using the tool.

Example: From 2003-2007, how many traffic-related deaths were there in Fraser Health Authority as a result of alcohol and drug involvement?


Collision location and collision year

  • Region – Health Authority – Fraser
  • Year – check boxes from 2003-2007

Collision information
Contributing factors – Sub Factor

  • Human Action – check alcohol and drugs involved (you will need to expand the arrow button to obtain the second level choices)

All other selections are checked as per default
Select number of deaths
Under broken down by: select contributing factor and collision year

Press Submit

Output: A summary of your selection will be presented at the top. Your results will be displayed as a table. You can export your results either in excel, word or as a text document. If you would like to see the information in a chart, select the chart tab at the top.


Interpretation and meaning of the data charts and tables is the responsibility of the user. If you require assistance in interpreting the charts and tables, or if you have further questions, please contact BCIRPU at 604-875-3776.

Definitions for some terms can be viewed in the glossary (enter the data tool to view the glossary).

We have tried to ensure that the TAS tool provides as accurate information as possible. When an incident form is completed by the attending police, up to 4 contributing factors are recorded. The TAS data tool allows the user to view each of these factors independently as well as in combination. When contributing factors are combined, the tool eliminates double counting. In the example above, the query results break down the contributing factors as:

  • Alcohol involved
  • Drugs involved
  • Alcohol involved and drugs involved

Frequently Asked Questions

1. What is TAS?
The Traffic Accident Police Investigation Report (MV6020, formerly known as MV104) is completed by a police officer at the collision scene. In many police jurisdictions, the police do not attend all reportable collisions; in the case of unattended collisions, a driver is required to report the collision to a police station if it meets the injury or aggregate damage criteria. The data from the completed MV6020s are entered into the Traffic Accident System (TAS) database. The TAS database provides detailed information at the “accident” level, describing factors related to the crash itself such as contributing factors (speed, alcohol use, distracted driving); the “entity” level describing the vehicles involved in the crash, and the “victim” level describing type of victim (occupant, pedestrian, etc) and outcome (death, major injury, minor injury).

3. What is the difference between human action and human condition under contributing factors?
Human action involves “actions” that the person conducts such as speeding, failing to signal, improper turning, driving without due care, etc. Human condition involves the state of the person as a result of some action such as alcohol involved, extreme fatigue, illness, etc.

*Last update for TAS data – June 2020.

Data is from the MV6020 Traffic Accident Report, a report completed by Police to record details of a collision. Not all collisions in British Columbia are attended by police or reported to police, therefore the counts of victims should not be considered comprehensive.

Only injured or fatal victims have been included; homicides, suicides and death from natural causes are EXCLUDED. Victims of collisions on roads where the Motor Vehicle Act does not apply (such as Forest Service roads, industrial roads and private land), and off-road snowmobile collisions are EXCLUDED.

In 2008, legislation changed so that police are no longer required to attend all crashes and attendance is at their discretion. For this reason, there has been a marked decrease in the number of police-attended reports submitted. We caution that decreasing crash counts which include police-reported data may be misleading. The injury counts are therefore only available until 2007.
