Abstract
The purpose of this paper is to verify maintenance of the life route in Amami-Islands to which depopulation and aging go, and is to propose a future transportation theory for autonomous and sustainability. I paid attention to regional economy, especially Amami-Island, because Transport demand depend on trip which is happened by it's economic activity in there. First, I studied social transport change, decentralization of authority and source of revenue.
Following, I studied Amami-Islands shipping transport for Life security. I described so telling management that it's company is almost taken a grant. Intra Amami-Islands shipping transport is more telling than inter one. There are water taxies of intra one without life security. I focused it's efficiency run. I think Amami sipping is serving to keep autonomous society, because it connects Amami-Islands with Kagoshima while air transport connecting Amami with Tokyo.
Passenger shipping Liner is heavy load for revenue, but it contributes to enhance to local autonomy. Because it keeps Amami-Islands shipping transport, especially Life security routs continuing, and it is increasing demand I discussed how to Amami-Islands active.
From a viewpoint of life security, Islands shipping transport study gives much suggestion rather than main lands one. I want to continue studying of the transport policy of the period of maturity, especially islands shipping transport for autonomous and sustainability.
