Allstate Insurance Company says Edmonton's vehicle collision rate has decreased over the past two years.

Edmonton's collision rate may have dropped, but the city continues to have one of the worst rates in Alberta — and Canada, a study released Wednesday suggests.

In Allstate's fifth annual Safe Driving Study, researchers found that Edmonton's collision rate decreased by 9.2 per cent between 2011 and 2013, continuing a similar decrease from 2009 to 2011. However, the city still ranked 44th out of 50 Canadian communities — and dead last out of seven Alberta cities in the study.

The study was based on all Allstate Canada customer claims information in Alberta, Ontario, New Brunswick and Nova Scotia over the past two years.

It also ranked 50 Canadian communities by the frequency of collisions per 100 cars insured by Allstate.

In Alberta, the study looked at customer information in Medicine Hat, Spruce Grove, Lethbridge, Sherwood Park, St. Albert, Calgary and Edmonton.

Medicine Hat had the lowest collision frequency out of all the communities surveyed in both Alberta and Canada, at 2.93 per cent.

Calgary's rate sat at 5.72 per cent while Edmonton's came in at 5.84 per cent.

However, Allstate says the overall trend in cities across the country show decreasing collision rates — nationally, Canadian drivers had 5.3 per cent fewer collisions during the survey period than in the previous 24-month period.

In Alberta, the overall decrease was 7.4 per cent, putting it in last place among the four provinces studied.
