Study identifies Canada’s worst traffic bottlenecks

Canada’s top 20 most congested traffic bottlenecks may cover just 65 kilometres, but they collectively cost drivers over 11.5 million hours and an extra 22 million litres of fuel per year. These are two findings of Grinding to a Halt, Evaluating Canada’s Worst Bottlenecks, released by the Canadian Automobile Association (CAA).

Canada’s top 20 most congested traffic bottlenecks may cover just 65 kilometres, but they collectively cost drivers over 11.5 million hours and an extra 22 million litres of fuel per year. These are two findings of Grinding to a Halt, Evaluating Canada’s Worst Bottlenecks, released by the Canadian Automobile Association (CAA).


Studies show that bottlenecks are the single biggest contributor to road delay, far outpacing traffic accidents, inclement weather and construction. The report provides data-based evidence for decision-makers to use when making decisions on infrastructure investment and environment policy.  It includes the cost to Canadians of these bottlenecks in terms of lost time, productivity and added greenhouse gas emissions.

“Traffic congestion is a major source of stress for Canadians. Our study concludes that traffic bottlenecks affect Canadians in every major urban market, increasing commute times by as much as 50 per cent,” said Jeff Walker, vice-president of Public Affairs for CAA National. “Reducing these bottlenecks will increase the quality of life for millions of Canadians, save millions in fuel costs and reduce greenhouse gases, helping contribute to Canada’s climate change commitments.”

Toronto has ten bottlenecks in the top 20, Montreal five, Vancouver four and Quebec City one. Other cities such as Calgary, Edmonton, Regina, Winnipeg, Ottawa and Halifax also experience serious traffic delays.

    Put ‘people, not cars' first in transport systems, says UN Environment chief
    Lack of investment in safe walking and cycling infrastructure not only contributes to the deaths of millions of people in traffic accidents on unsafe roads and poorly designed roadways, but also overlooks a great opportunity to boost the fight against climate change, according to a new UN Environment report. In Global Outlook on Walking and Cycling, the UN Environment Programme (UNEP) claims that greater investment in such infrastructure could help save millions of lives and reduce emissions of global w

    Road pricing is inevitable – because the ‘user pays’ principle is fair
    We pay for roads through our taxes: the poor pay proportionately more, and effectively subsidise the rich. It would be fairer to accept the ‘user pays’ principle, says Dr John Walker. Road pricing is already used worldwide to combat congestion and pollution, to compensate for falling revenues from fuel duty (‘gas tax’), to provide an alternative (and fairer) means of charging motorists than the 80-year old fuel tax and to improve the efficiency of and expand transport infrastructure. However, it could and s

    Washington, DC, tops list of gridlocked US cities
    The 2015 urban mobility scorecard for the US, published jointly by the Texas A&M Transportation Institute and Inrix, indicates that urban areas of all sizes are experiencing the challenges seen in the early 2000s and population, jobs and therefore congestion are increasing. The US economy has regained nearly all of the nine million jobs lost during the recession and the total congestion problem is larger than the pre-recession levels. Cities of all sizes are experiencing the challenges last seen before t

    Adaptive control reduces travel time, cuts congestion
    Situated in San Diego County, California, the growing city of San Marcos has seen its population increase by 53.5 per cent since the turn of the century. Although this dramatic population increase has spurred economic growth bringing new business, homes and opportunities to the city, it has also increased traffic congestion along its central corridor, San Marcos Boulevard. This became the most congested arterial in the city, and, by 2006, the second-most travelled corridor in San Diego County.
