LTA geospatial open data locates traffic signal aspects—ground-mounted heads, overhead arrays, green filter arrows, beacons, and related hardware—across Singapore’s road network. GEOJSON and KML layers help transport engineers audit junction control inventory and support smart-mobility prototypes. Researchers modelling visibility or accessibility at crossings can join aspect points with junction geometry. The ad-hoc release documents physical signal assets rather than live signal timing.
Traffic lights consisting of signal aspects such as ground, overhead, green filter arrow, beacons, etc to control traffic flow.
Land Transport Authority GeoJSON of traffic-signal aspects across Singapore—ground, overhead, green filter arrows, beacons and related devices that control road traffic flow. Transport engineers, autonomous-driving teams, and GIS users locate signal hardware and overlay it with junctions, lane markings and road-network layers. Layer coverage begins October 2025.
