As for passenger transport, roads still dominate the mobility as can be seen in Table 1.
Development of roads still dominates inside Java, Sumatra, and crossing of those two islands.
As a matter of fact, the crossing mobility volume between Java and Sumatra exceeds mobility
volume inside Sumatra itself. Outside Java, the largest land movement occurs between
Balikpapan-Banjarmasin, its corridor region and hinterland. For Sulawesi, the only significant
mobilization is in South Sulawesi.
