Abstract: Zonal transportation hubs providing an interface between public and private road-transport at highway junctions. A public-transport zone has a dedicated road network connecting the highways to a station and a separate private-transport zone has a separate road network connecting the highways to a parking lot. A pedestrian zone provides a uninterrupted route between the parking lot and the station.

Abstract: A spiral road junction system for connecting a plurality of highway spokes via a spiral road junction comprising adjacent-spoke connecting roads associated with each highway spoke, and a ring-road interchange traversing all the highway spokes. The ring-road interchange provides a continuous path from a slip road diverging from an entry highway spoke to an access road merging with an exit highway spoke.

Abstract: The present disclosure is directed to providing a spiral road junction system. More specifically the present disclosure relates to a system for connecting a plurality of highway spokes via a spiral road junction comprising adjacent-spoke connecting roads associated with each highway spoke, and a ring-road interchange traversing all the highway spokes. The ring-road interchange provides a continuous path from a slip road diverging from an entry highway spoke to an access road merging with an exit highway spoke.
