You must separated paths for bikes and cars. We did that in Paris in the past few years and bike usage has exploded. It simply becomes safe (and pleasant) to ride a bike and people tends to follow others when society make a reasonable choice (favor bikes over cars). And it was/is not easy to make space for bike in such a dense city.
