Abstract
As a large archipelagic country, Indonesia has certain characteristics in terms of its transportation services. Each island or region has its own modes characteristics, the integration of which are still developing. To achieve an efficient transport system, a Indonesia is an archipelago with more than 17,000 islands spread through out the country.
Nevertheless, inter-island transportation has not been perceived as having a strategic role.
Being the most developed islands Java and Sumatra, in economic sense, have left the other
islands behind, and these made that intra island wise transportation mainly roads becomes
dominant in carrying both passengers and goods, especially when rail transportation has been
decreasing since 1939.
