If you can physically drive 50+ mph down a street signed for 25 mph then whoever built the road may have been thoughtful but they certainly weren't thinking about safety.
Signs and warnings rank very low in the hierachy of engineering controls.
The safest option would be to physically prevent vehicles able to travel at greater than 15mph from being in areas with children.
The next safest would be to redesign the street to prevent high-powered vehicles from being able to travel at greater than 15mph.
