Extrude along path adjusting the segment count around curves

My end goal is to extrude along a bezier curve and create a low-poly landscape. The main issue is once I have the bezier curve all setup I only see a single option for the number of segments to create when converting to a mesh. The problem with that is that the segments are evenly separated regardless of the curvature. What I would like to do is get more segments at the curves and less in the straighter sections to keep the poly count reasonable.

To illustrate what I mean in the image linked below I would like to get more segments in the red section and less in the red. Is there any easy way to pull something like that off?
