Here in Ft. Simpson & the majority of the small, rural, remote communities, LAND USE PLANNING is the only strategy that could likely work or have a chance of being considered. As Ryan & Kjell have identified, plans to reduce the distances people are traveling in town or between communities would have the most/only hope for implementation.
I’ve been wondering what it would take for a decent “shuttle run” to exist between Ft. Simpson & Hay River and/or Yellowknife … to help people get to meetings in either of those places, or do their supply runs (although space would be needed for cargo for return trips). But then you’d be asking a bunch of people to “hole up” in one vehicle for 4 & 7 hour driving times to get where there are going & then with minimal ability to get around town once they are there. Somehow, it would have to be promoted as a very fun bus, with perhaps a few amenities & perks for riding the shuttle.
People are quite tied to their big trucks in most of the NWT communities & the gravel/rough roads necessitate a more durable vehicle, so I think the greater merit will be in figuring out ways to decrease the carbon footprint of the vehicles folks are driving & reinforcing the inefficiencies of idling your vehicle.
