Thailand also has an extensive road network. With a road density of around 125.7 kilometers per thousand square kilometers, Thailand presently ranks third in the ASEAN region. With the possibility of a Trans-Asian highway networking most countries on the Asian mainland, Thailand could become a regional logistics hub of ASEAN as it is contiguous with countries such as Laos, Cambodia, Malaysia and Myanmar. In addition, the Government has taken initiatives to improve the country's road and rail infrastructure network to match global standards. In 2005, the government announced a plan to INVEST US$45 billion in infrastructural development over the next 5 years.
