   I was thinking of setting speed limits based on the road's design standards.   
   Before Lake Shore Drive in Chicago was rebuilt, it featured short entrance   
   ramps with tight radius curves (including tiny cloverleafs originally)   
   and narrow lanes. But the speed limit was 55 mph. It was rebuilt to modern   
   expressway standards and clearances were improved at all viaducts   
   (despite not allowing trucks), all ramps were replaced and in most places   
   where there was room, merging lanes were added. With no room, there are   
   traffic lights.   
      
   But the speed limit is lower today, especially in winter to keep salt spray   
   off median trees.
