Aerobus offers the lightest elevated guideway. It is considerably less expensive than either light rail, Automated Guideway Transit or Monorails.

Because of the extraordinary tensile strength of steel cables (250 to over 300 tons) and their relatively light weight, supporting Pylons may be placed as much as 600 meters (about 2,000 feet) apart. This spacing permits convenient crossing of rivers, valleys and even elevated structures. In typical dense, urban applications, pylon spacing of 200 meters (over 600 feet) for straight runs, or 100 meters (310 feet) for slight curvatures (2 - 3 degrees per segment) are recommended.

The above two characteristics combine to make Aerobus the least costly elevated transit system known today in the medium capacity transit range. (10,000 - 30,000 passengers per hour per direction.)
