Solution:

Currently, there is no dedicated command in AutoCAD or AutoCAD LT to simplify such complex polylines. On AutoCAD Map 3D and Civil 3D, a dedicated function is available. See: About Weed Polylines.
 

Note: The process is called weeding and there are several custom LISPs which may be used in AutoCAD to achieve this.
