Speed limit signs are almost useless, especially if not enforced (preferably by speed cameras, preferably without announcing their location with signs). The correct solution to get that guy to stop is to make the street less deadly by design. It should be narrowed, made more winding and have visual 'clutter' added like trees, flower planters, etc. It should be intensely uncomfortable to speed more than 5-ish mph, and people who choose to do so anyway need to meet a traffic calming measure and be on the phone to their body shop well before they speed up enough to endanger a life.

In our neighborhood, some streets have speeding problem. Some neighbors asked city to install speed bumps but the city refuses to do so those because then emergency vehicles will be slowed down too.

  In our Canadian city, the speed bumps have breaks that allow wide-axle vehicles (buses, emergency vehicles) to pass with minimal braking[0]. Some large passenger vehicles can get through the same way, but for most vehicles it's a speed bump. The issue with speed bumps is that it's just not a good traffic calming design. Why should a vehicle slow down to, say, 20 kmh at random spots when the limit is 40 kmh? Traffic tables[1] are much better, in that if they're properly installed, you don't need to slow down if you're already going the speed limit. They should be installed at pedestrian crossings to make the crossing level with the sidewalk (cars go up and down) instead of being level with the street (pedestrians go down, then up). The street should be narrowed at pedestrian crossings too, and at all intersections (no parking there anyway).
