Land Transport Authority (LTA) maps gantry structures spanning carriageways or along roads to support signage and electronic equipment such as ERP and EMAS in Singapore. GEOJSON and KML datasets assist transport engineers, navigation app developers, and researchers studying road-based charging and incident management infrastructure. Urban mobility analysts can relate gantry locations to congestion pricing and expressway monitoring networks. This ad-hoc geospatial collection documents LTA’s roadside gantry inventory on data.gov.sg.
