Leverage weather data and snowplow sensors to more efficiently plow our roads

I recently heard about an interesting pilot project in Vaughan whereby they used weather data and software to more efficiently deploy when to salt their roads. They were able to reduce the amount of salt they used by utilising some data science. 

I also think the Markham could apply the same intelligence to its snowplowing efficiency. Not all roads need the same level of snowplowing attention. As an example, 7.5CM may not be that tough to navigate it its a flat road; however, in the case of my road that has quite a steep grade it can often become impassable with 5+CM of compacted snow. Why not make snow plow routes more variable and targeted toward the more difficult roads that are more susceptible to snow based upon gradient, school areas, parks, etc.
