Some of the notable developments for the Asian Highway were: (a) the proposal for inclusion of about 5,247 km of highway network as part of the Eurasian Highway network, and an extensive programme to enhance the standards of the current highways, including increasing the length of dual carriageway highways in Turkey; (b) installation of the harmonized Asian Highway route signs in Thailand; and (c) completion of road sign and equipment inventory along Asian Highway routes in Sumatra (south Sumatra border-Jamoi–Pekanbaru–Dumai) and Java (Surabaya-Surakarta-Semarang) in 2012, and a plan for a similar exercise in 2013 in the Dumai-Medan-Banda Aceh and Semarang-Cikampek-Jakarta-Merak sections of the Asian Highway in Indonesia.
