This invention provides methods of guideway construction and vehicle operation for a three-dimensional transportation system, in which a vehicle changes lane or direction by widening or narrowing the width between its left wheels and its corresponding right wheels. In such a transportation system, vehicles diverge from a source lane and merge into a target lane aerially either above or below the tracks, through the empty space between the left guideway and the right guideway. A transportation system in which traffic lanes could be stacked vertically one above another, and additional lanes could be added later without additional land usage. In such a transportation system, a vehicle could raise or lower its center of gravity in the vertical direction to offer the advantages of safe operation and easy loading/unloading. Such a transportation system could accommodate dual-mode vehicles. Such a transportation system is suitable for automatically moving people and goods.
