LTA publishes annual counts of traffic lights maintained by the authority on Singapore roads. The Traffic Lights CSV in this collection helps transport engineers benchmark signal inventory growth against network expansion. Analysts can cross-reference LTA’s DataMall portal noted in the official description for related mobility datasets. Figures cover long-run annual snapshots within the catalogued year range.
Facilities include only those maintained by the Land Transport Authority (LTA). Other road structures maintained by the LTA include culverts, retaining walls, street lightings, etc. Ref: https://www.mytransport.sg/content/mytransport/home/dataMall.html
