And here: Traffic-related air pollution a growing concern in Canada(Karen Graham, Digital Journal, Oct 21, 2013)
Today we review research into the public health risk posed to Canadians (and citizens of other countries) from traffic –related air pollution, especially to the third of its population (10M) that lives within the length of a football field (100 m) of major roads with heavy traffic. Solutions include, first and foremost, reducing vehicle emissions by reducing traffic congestion, keeping high emission vehicles, such as trucks and buses, away from schools, day-cares and retirement homes though better zoning to reduce sprawl, as defined in official municipal plans, and encouraging alternate commuting modes with urban congestion charge zones among other options.
“approximately 21,000 people die prematurely from air pollution each year in Canada, about 9-fold more than the number killed in traffic accidents.”
“About 10 million people -- 32% of the population of Canada -- live within 500 m of highways or 100 m from major urban roads, areas in which they are exposed to elevated levels of traffic-related air pollution”
"This high prevalence of exposure, in addition to evidence of associated health problems, suggests that traffic-related air pollution is a substantial public health concern in Canada,"
“options to help mitigate the effects of traffic-related air pollution:
- Reducing vehicle emissions: introducing programs to remove or retrofit high-emission vehicles; reducing traffic congestion; expanding infrastructure for electric cars
- Modifying current infrastructure: limiting heavy truck traffic to specific routes; separating active commuting zones (e.g. cycle and walking routes) from busy roads
- Better land-use planning and traffic management: locating buildings such as schools, daycares and retirement homes at least 150 m away from busy streets
- Encouraging behavioural change: creating policies to reduce traffic congestion in specific areas and encouraging alternative commuting behaviours.”
