To level up you have to do many edits and doing road edits will level you up much faster, however to level 1 users they're not allowed now to make road edits, but only allowed to make "places" edits. To pass this restriction you need to contact Waze team, when they allow you the road edits you'll be able to edit more areas and gain more points.
