Land Transport Authority (LTA) road asset statistics summarise lengths of public roads maintained by LTA in Singapore, including lane-kilometre measures. CSV datasets Length of Roads (Kilometres) and Length of Roads (Lane-Kilometres) cover 2005 through 2017 with definitions for collector and local access roads in the official notes. Transport planners can compare road inventory trends while excluding roads maintained by other agencies listed officially. Reported lengths reflect realignment adjustments noted for Changi Coast and Ferry roads.
Official description
Whole Roads or Section of Roads including lane maintained by LTA.
Collector roads are built primarily to feed traffic from local onto arterial roads. It also provides access to adjacent land uses.
Local access roads provide access to various types of land uses. These roads are generally smaller, in terms of width, than collector roads. All public roads maintained by LTA are paved.
Road Length in lane-km data includes all public roads maintained by the Land
Transport Authority. It does not include certain roads such as those maintained by the National Parks Board (Nparks), Housing and Development Board (HDB) and Urban Redevelopment Authority (URA), JTC Corporation (JTC) - including roads in Jurong Island , National Environment Agency (NEA) , Ministry of Home Affairs (ISD), Ministry of Home Affairs (POLICE), Singapore General Hospital (SGH) , Public Utilities Board (PUB), Singapore Land Authority (SLA) , AGRI-Food and Veterinary Authority of Singapore (AVA) as well as roads within Sentosa Island (SDC), airports (CAAS), seaports (PSA), universities (NTU, NUS), Community Improvement Project Committee (CIPC) , Private, Ministry of Home Affairs (prisons), Immigration & Checkpoints Authority (ICA) and military (MINDEF) areas.
The road length is shorter than the as build roads due to re-alignment of Changi Coast Road (Major Road) and Changi Ferry Road (Collector Road).
Review how Singapore’s road network length evolved from 2005 to 2017 with annual figures by road type. Published by the Land Transport Authority in CSV format, the dataset links year, road type, and road length in kilometres for transport planning, infrastructure investment analysis, and comparisons across expressways, arterial roads, and other categories. It supports Singapore transport geography research and searches on road-kilometre statistics and LTA road inventory trends.
