This is a hidden gem! UBC and Translink have developed this cycling route map that provides shortest route, lowest slope route, most vegetated route, and lowest traffic pollution routes. They also include handy facts like distance, time (based on your speed), how much GHG emissions you’ve prevented, calories burned, and average NO2 levels along the route.
SO COOL! I’ll be using this one for any new trips outside my usual routes! If you start using it too, post feedback here.
