Hey there bud, some tips to help on mapping out maxspeed and sidewalks as i have been going ham on it lately. Check out the SLIM maps https://maps.edmonton.ca/map.aspx for the max speeds and special school/playground zones. split ways to help tag the sections with conditional speeds and add this tag and key "maxspeed:conditional	30 @ 07:30-21:00"

here is an example to help https://www.openstreetmap.org/way/106605128

sidewalks are a bit of a beast to map onto the roadways so i have been just drawing them out now, but 100% get no one wants to go through that effort.

hope that helps!
