About the Cyclotron


A38 Cycle CounterThe West Midlands Cyclotron is a personal project inspired by the digital cycle counters on the Bristol Road.

It provides near real time insight into the numbers of cyclists using city roads and cycle routes.

Liz Clements, Birmingham City Council Cabinet Minister for Transport says: 'The Cyclotron is a fantastic resource for those of us promoting cycling in Birmingham and the wider region.'

Count Highlights

The top three average cycle counts between February 2023 and January 2024 are:


Cycle counts are taken from Transport for West Midlands' and Birmingham City Council's machine learning vision sensors. These are primarily aimed at motor traffic but also detect bikes through that machine learning. Most counters count in two directions and both are included.

The sensors are owned and maintained by TfWM and were purchased as part of a grant funded government project. The data is shared as part of TfWM’s Data Insight Service, which collates transport data across the West Midlands on behalf of the 7 authorities (Birmingham, Coventry, Dudley, Sandwell, Solihull, Walsall, Wolverhampton) and TfWM itself.


The design re-creates the idea of individual LEDS making up the characters and charts, the coordinates of each diode calculated and then re-calculated with each animation.

The Cyclotron was built in Svelte, an open-source web framework used by many of the World’s major news rooms for their digital output.
