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.

    Every year in America cost benefit analysis is carried out on dozens of ITS installations and pilot studies and the findings, along with the lessons learned, are entered into the Department of Transportation’s (USDOT’s) web-based ITS Knowledge Resources database. This database holds more than 1,600 reports and periodically the USDOT reviews the material on file to draw conclusions from this wider body of evidence. It has just published one such review ITS Benefits, Costs, and Lessons Learned: 2014 Update Re

  • Canadian authorities convinced of enforcement safety benefits

    Cost-benefit analysis invariably finds highly in favour of speed and red light enforcement, particularly so in Edmonton in the Alberta province of Canada, where authorities need no convincing of the merits of road safety engineering. Justification of enforcement efforts on economic grounds has been reinforced this year, by a study of the costs and benefits of red light enforcement. New York-based economic research firm John Dunham & Associates carried out this latest analysis for American Traffic Solutions

    With poor urban air quality shortening lives and fines being imposed for breaching pollution limits, authorities are seeking ways to clean up their cities. Poor air quality is topping the agenda for city authorities across the globe. In the UK, for example, a report from the Royal Colleges of Physicians and of Paediatrics and Child Health, concluded that poor outdoor air quality shortens the lives of around 40,000 people a year – principally by undermining the health of people with heart and/or lung prob
