Hmm, I deal with metal humps on the Manhattan Bridge that form similar sized bumps. The trick I use is to maintain a steady speed, stand out of the saddle and aim for the smoothest bits. I don't notice the bounce if all goes well. If you look on hump on your photo you'll see that in between the reflector mounts there is a bit of smooth surface aim for that. After your fall I'd avoid the gutter area.
