Tube Siren is a free, non-commercial, web-based app that aims to help Londoners inform their fellow passengers about busy tube lines and stations at peak hours.
The app is available online, simply visit www.tubesiren.com in your mobile browser to access it.
The app is an experiment in crowdsourcing, asking Londoners to update data for busy stations on the go. Anyone can report a busy station from a mobile device while statuses for each station are available online so you can check your route before you travel.
Tube Siren is currently available in a beta version.
The app lets users know if they can connect via station wifi...
...or an outdoor network signal on their smartphones.
Or visit www.tubesiren.com in your mobile browser to use the app!
You can follow @TubeSiren on Twitter, by the way, in order to receive news of updates to the app as well as periodic information about the tube network itself.
Tube Siren is available now. Just visit www.tubesiren.com in your mobile browser to use the app! Check back soon, as iOS and Android versions may be available in the future.
Tube Siren's data is 100% crowd-sourced. For each station passengers can report the fact that they are unable to travel because of queues or delays. Tube Siren looks at reports from the last 30 minutes and tells users checking the station in question whether or not they can expect to wait to get on a train.
Thatís the most important question of all. You should only report on a station if you are standing on the platform and cannot get on a train either because there is a delay in service, or because there is no space for you to get on. You should NOT report on a station just because you missed a train or because the station is a bit busier than usual.
Tube Siren is entirely web-based and youíll need an active internet connection to view the status of a station or make a report. However, thanks to Virgin Mediaís rollout of free wifi at many central tube stations, connecting to Tube Siren from anywhere inside a station, including on a platform, should be easy wherever wifi is provided.
