Personal Risk is the risk of death or serious injuries per 100 million vehicle kilometres travelling along a corridor
A corridor is defined based on the hierarchical classification of the road and intersecting roads. This approach was favoured as it generally resulted in a logical segmentation of roads into corridors where there were distinct changes in the physical nature and/or operation (traffic volume) of the road.

Collective Risk of a corridor is calculated by adding together the intersection and mid-block DSi casualty equivalents and dividing by the total corridor length in kilometres.

Motorcycle routes identified through consultation with motorcyclists and online motorcycle route sources.
Displays all crashes involving Vulnerable Road Users (VRUs), which includes motorcyclists (including mopeds), cyclists and pedestrians (including persons on skateboards, roller-skates, foot scooters and using mobility aids such as powered wheelchairs).
When selected, displays only alcohol-influenced crashes
When selected, displays only crashes where vehicular speed is a factor
When selected, displays only crashes where driver fatigue is a factor
Data displayed on the heatmaps can be narrowed down by searching for specific Crash Analysis System (CAS) codes (e.g searching for 359 gives you all crashes that were affected by the driver's attention being diverted by cell phones. A full list of all CAS codes is available here.
Multiple CAS codes can be searched for by separting them with a space or commas. (e.g 123, 512, 400 or 500 212 752)
Searching by categories is also possible, e.g. searching for code 100 will update the heatmap with all alcohol/drug related crashes (CAS codes 101-109).
Heatmaps are coloured by calculating risk for each point and scaling those numbers between 0-1, which then maps onto:
