Mapping experts from University College London have visualised every one of the 114,000 bus journeys that take place in London every day

Cartography experts Joan Serras and James Cheshire, both of University College London's Centre for Advanced Spatial Analysis (CASA) have mapped every one of London's 114,000 daily bus journeys.

The map, which can be seen in full size at MappingLondon.co.uk, shows the exact route of every individual daily bus journey including all stops.

Thicker, redder lines represent roads used by several buses per day, while fine yellow strands represent the quieter routes. Where a section of road is not used by buses at all, it is not marked on the map.

The image above shows a large scale view of bus travel in Aldwych. Waterloo Bridge is used by the most buses, while Park Lane and the roads immediately north of Elephant and Castle also stand out as particularly busy.

Timetable data from over 22,000 London bus stops was used to create the map. The image below gives an idea of just how densely distributed these points are.

The graphics were produced using data from the National Public Transport Data Repository and Digimap's Intergrated Transport Network layer.
