Starting with the areas that already have sufficient density but don't have safe bike infrastructure: build a network of safe bike infrastructure. The area I live in is like this. Philly and its surrounding suburbs are absolutely already dense enough to make cycling a practical way to get around, but it's not particularly safe or pleasant to do so. So there's a lot of low-hanging fruit in places that are already pretty dense. But in addition to that, upzone broadly and remove parking minimums. I think there's a good chance that leads to higher densities pretty quickly in areas with high demand.
