These are the 20 worst traffic bottlenecks in Canada according to CAA

Jan 11 2017, 1:45 pm

In a new report commissioned by the Canadian Automobile Association (CAA) entitled, Grinding to a Halt: Canada’s Worst Highways, the automotive association breaks down the worst traffic bottlenecks in Canada.

The first report of its kind to be conducted in Canada, the results shed light on the time, money, and environmental impact these hours of traffic have on Canadians and our country.

Data was collected and analyzed from Vancouver, Calgary, Edmonton, Regina, Winnipeg, Toronto (including the Hamilton and Oshawa CMAs), Ottawa, Montreal, Quebec City and Halifax.

A bottleneck is defined, quite simply, as “severe traffic chokepoints where demand far exceeds available highway capacity.” And, in fact, a similar US study commissioned by the United States Federal Highway Administration (FHWA) found that bottlenecks made up 40% of the road delay share in the US, compared with 25% for traffic incidents, making it the number one reason for delays on the road.

A few things from the report worth noting when considering the ranking:

  • Although the ranking of the Vancouver bottlenecks are not as severe as they are in Toronto and Montreal, the actual vehicle speeds that drivers experience into and out of downtown Vancouver are in fact as bad as or worse than they are in those two cities.
  • The Travel Time Indices (TTI) is the travel rate during a specified period of time relative to the travel rate in free-flow conditions. For example, if it takes 45 minutes to travel between points A and B during the morning peak and it takes 30 minutes to travel between the same points during free-flow conditions, the TTI is 45 / 30 = 1.50.
  • Compared with US bottlenecks, Toronto’s 401 bottleneck ranks among the top ten (Canada and US combined), while Montreal’s top bottleneck ranks among the top 20.
  • Toronto’s 401 bottleneck costs commuters over 3 million hours annually.
  • The study examined traffic flows and speeds on approximately 3,000 kilometres of highways across Canada, but the total length of the top 20 bottlenecks found is only 65 kilometres long.
  • The study was conducted over all four seasons in February, May, August and November of 2015, resulting in the examination of 15,000 urban segments and almost 180 million speed observations.
  • Altogether, the delay costs from the top 20 traffic bottlenecks in Canada is close to $300 million per year.
  • Toronto has 10 of the top 20 traffic bottle necks, Montreal has five, and Vancouver has four.
