Elevated Light Rail Transit (LRT), People Movers and Monorails generally require 50-60 concrete or steel columns (or frames) per mile to hold up a two-way guideway for bottom-supported vehicles. Aerobus, in straight line stretches (or in very slight curvatures) for two-way suspended tracks, may require no more than 5 to 10 pylons per mile. This together with the replacement of heavy beams by slender cables, represents a very significant cost saving in the guideway structure.

Simultaneously, the unobstructive suspended rails cast barely any shadows and represent the least possible disturbance to the aesthetic sensitivities of urban planners and the public.

The unusually smooth ride of a cable-suspended vehicle, together with the novelty of riding "all above the urban snarl" in a smoothly gliding vehicle, had great public appeal and acceptance in Mannheim.

The reduced quantity of pylons results in a corresponding savings in the costs of utility relocations.

The reduced quantity of pylons and elimination of fabricated guideway segments results in a reduced construction time.

The under-slung bogie suspension design allows the performance of a super-elevated alignment (in curved sections with solid guideway) without costs associated with a more complicated structure incorporating super elevation.
