Tube Heartbeat


Tube Heartbeat visualises one of Transport for London’s most interesting and detailed open dataset, RODS. This has data on the approximate weekday volume of passengers between each pair of stations on the network, and entering/exiting the stations, at 15-minute intervals. Mapping this, as Tube Heartbeat does, shows a distinctive pulse, or heartbeat, as commuters surge in and out. There are locally interesting patterns too – a late night “palpitation” as the theatres close, early afternoon flutters as school kids get the tube home in suburbia, and double-morning rush hour peaks in parts of east London, perhaps showing the traditional blue-collar 8am start and the white-collar 9am start.

Click “Pause”, and then click on any station, or line between the stations, to see an interactive graph showing these ebbs and flows. You can also compare with an older RODS from 2012, to see where the commuter populations are rising (or otherwise).

Tube Heartbeat is a commission for HERE Maps and uses the HERE JavaScript API to show the tube data, and the HERE Map Tile API for the pleasing background mapping. The HERE JavaScript API is optimised for showing data like this, resulting in fluid animation and navigation that should work well both on desktop and smartphone.

  1. Hello there, I am the publisher at Batsford books. I love the website and the lovely marriage of fascinating information and eye-catching graphics. I would be very interested in talking over book ideas if ever thought you would like to make some of the material on the site into a very handsome and illuminating book. Please feel free to call or email if you’d like to even talk over the idea. My email is tpersaud [AT]

    very best wishes

  2. I am one of those passionate “Geo-geeks” and “Geo-people” who is just too excited about everything Geo and Management. Location information and spatial technologies are just too big to take a back seat and watch them revolutionize the world. Always curious and looking for ways to innovate, I guess that it comes naturally by the gene pool I inherited from an engineer Mom and a researcher Dad.
