U of T Engineering researchers studied the attention actions of drivers at busy Toronto intersections and located that greater than half did not make crucial scans for pedestrians or cyclists at proper turns.

Throughout a summer time that has seen a string of vehicle-pedestrian and vehicle-cyclist accidents within the metropolis — with 21 fatalities as of June — this research provides new perception right into a driver’s misallocation of consideration when making activates busy metropolis streets.

“There are a variety of visible and psychological calls for on drivers at intersections, particularly in a dense, city surroundings like downtown Toronto,” stated Nazli Kaya, who’s main the analysis beneath the supervision of Professor Birsen Donmez, Canada Analysis Chair in Human Elements and Transportation.

“Drivers have to divide their consideration in a number of instructions, whether or not it is different automobiles, pedestrians or street indicators and visitors alerts — visitors security immediately turns into a serious concern,” she stated.

That is the primary research to this point that used eye-tracking tools to precisely assess the place drivers had been trying when turning at an intersection.

The individuals ranged in age from 35 to 54, all with greater than three years of driving expertise. The drivers had been required to make proper turns at Palmerston Avenue from Bloor Avenue, a signalized four-way intersection, and at Main Avenue from Bloor Avenue, an uncontrolled T-intersection resulting in a smaller street. Each areas required drivers to securely flip proper throughout a devoted biking lane alongside Bloor Avenue.

The researchers’ research discovered that:

    * Eleven of the 19 drivers did not stare upon an space of significance, the place cyclists or pedestrians can be positioned, earlier than turning.

    * All attentional failures had been associated to not making frequent over-the-shoulder checks for cyclists.

    * There have been extra failures turning into Main Avenue, as a result of parked automobiles blocking drivers’ views of the bike lane.

    * Attentional failures had been extra seemingly for many who drove extra continuously in downtown Toronto.

It appeared that drivers much less accustomed to an space had been extra cautious when turning.

“The outcomes had been fairly shocking,” stated Donmez. “We did not count on this degree of consideration failure, particularly since we chosen a gaggle which are thought-about to be a low crash-risk age group.”

Donmez believes adjustments to street infrastructure is required to enhance visitors security, pointing to the inconsistent implementation of motorbike lanes as one of many many hazards dealing with Toronto streets. “I believe it is an infrastructure subject. I do not suppose it is an training subject. Once you have a look at the bike lanes within the metropolis — they seem over right here, however disappear there — the extra unpredictable the street guidelines are, the tougher it’s.”

Till these infrastructure adjustments are made, “Drivers must be extra cautious, making over-the-shoulder checks, and doing it extra typically,” stated Donmez.

“The takeaway for pedestrians and cyclists: drivers aren’t seeing you. Not essentially as a result of they’re dangerous drivers, however that their consideration is simply too divided,” added Donmez. “When crossing a road, your assumption ought to be that the automobile does not see you.”


This analysis was not too long ago introduced on the Canadian Affiliation of Street Security Professionals (CARSP) Convention. Within the fall, Kaya and Donmez are planning to construct on their work, conducting street assessments with a bigger participant pool and extra intersection areas all through the town.
