Traffic information services
Traffic or Macet is the word people mention every time they're asked to describe major cities like Jakarta, Bandung, or Surabaya. Radio station like Elshinta is famous for its traffic information, thanks to listeners' active participation in providing information through SMS and regular update from "official" sources like Jakarta Metropolitan police or Bogor police when it comes to Puncak area.
Technology, especially ICT, has triggered some people to develop new traffic information services, live, web-cam-based through digital platforms like iPhone and Blackberry. There are some web portals developed to provide close to real-time traffic situation like Lewatmana.com, Macetlagi.com or Infolalulintas.com. The first two seems increasingly popular, at least based on traffic from web users identified by Alexa.com. Lewatmana.com tops the list, currently ranked 2132 in Indonesia according to Alexa.com, while Macetlagi.com is ranked 4409. Infolalulintas.com is far behind these two at 27994.
