The minister believes that the use of the mass transportation means will also result in a significant reduction in traffic congestion.

Land transportation has been instrumental in contributing considerably to the national economy. The Indonesian government is strongly committed to developing land transportation infrastructures, not only in Java but also in the rest of the country, he stated.
The government's commitment to developing a land transportation system across Indonesia is apparent from the construction of toll roads in Sulawesi, Kalimantan, Sumatra, and Bali as well as the planned development of train lines in Kalimantan, Sulawesi, and Bali, he remarked.
Quoting the results of a study conducted by the Institute for Economic and Social Research of the Economics School of University of Indonesia (LPEM FE UI), Pandjaitan explained that every one-percent hike in the construction of roads will raise economic growth by 8.8 percent.
Hence, the government has deemed it necessary to develop road infrastructures through public and private investment under a government and business entity partnership (KPBU) scheme, he stated.
"In addition, road connectivity, including through toll roads, serves as an essential component to drive economic transformation to the manufacturing and service sectors," he remarked.
Pandjaitan further highlighted the need for the government to focus on river, lake, and ferry transportation that also play a vital role as one of the connectivity factors. (antara)
