Adrian Verster, a University of Toronto PhD student in molecular biology, has a personal interest in Toronto's cycling collisions.

As a cyclist, he describes his travels on two wheels in this city as "quite frightening" due to Toronto traffic. But it wasn't until his girlfriend was involved in a bicycle-vehicle collision that he decided to look more deeply at road safety.

He took location-specific data from 3,100 collisions to determine Toronto’s worst intersections for cycling injuries.

Take a look at the map above for a visualization of his work.
