More than half of drivers don’t look for cyclists when turning right, reveals Uni of Toronto Engineering study

U of T Engineering researchers studied the eye movements of drivers at busy Toronto intersections and found that more than half failed to make necessary scans for pedestrians or cyclists at right turns.

This is the first study to date that used eye-tracking equipment to accurately assess where drivers were looking when turning at an intersection.

The participants ranged in age from 35 to 54, all with more than three years of driving experience. The drivers were required to make right turns at Palmerston Avenue from Bloor Street, a signalized four-way intersection, and at Major Street from Bloor Street, an uncontrolled T-intersection leading to a smaller road. Both locations required drivers to safely turn right across a dedicated cycling lane along Bloor Street.

The researchers’ study found that:

Eleven of the 19 drivers failed to gaze at an area of importance, where cyclists or pedestrians would be located, before turning.
All attentional failures were related to not making frequent over-the-shoulder checks for cyclists.
There were more failures turning into Major Street, due to parked vehicles blocking drivers’ views of the bike lane.
Attentional failures were more likely for those who drove more frequently in downtown Toronto.
It appeared that drivers less familiar with an area were more cautious when turning.

“The results were quite surprising,” said Donmez. “We didn’t expect this level of attention failure, especially since we selected a group that are considered to be a low crash-risk age group.”

Donmez believes changes to road infrastructure is needed to improve traffic safety, pointing to the inconsistent implementation of bike lanes as one of the many hazards facing Toronto streets. “I think it’s an infrastructure issue. I don’t think it’s an education issue. When you look at the bike lanes in the city — they appear over here, but disappear there — the more unpredictable the road rules are, the more challenging it is.”

Until those infrastructure changes are made, “Drivers need to be more cautious, making over-the-shoulder checks, and doing it more often,” said Donmez.
