| Minicab Flows across London |
|
|
| This image visualises the routes selected during almost 700000 minicab journeys across London. The red routes indicate highest traffic flow on each route, reducing the yellow, then white, then grey, where the fewest journeys are found. One can observe a concentration of movement along certain key routes through central London. ©Ed Manley |
| Inter-Nodal Cab Flows across London |
|
|
| In this image, the movements of private hire minicabs during the course of almost 700000 journeys across London are distilled into flows between key junctions on the road network. The image indicates how, according to this dataset, there is a generally higher level of traffic low and greater variation in route selection between nodes in central London. It furthermore highlights the most important routes travelling into and around central London, all formed simply through the 700000 route selections observed in this dataset. ©Ed Manley |
| Community Detection in Cab Routes in London |
|
|
| Having reduced the routes of minicabs during 700000 journeys across London into flows between important junctions on the road network, this image demonstrates how clusters in activity may be identified within this network representation. In this work, community detection algorithms are used to identify areas of common usage, linking together junctions that are often traversed during the same journey. With each colour representing a different cluster, it is possible to identify some of the important routes into central London, as well as a more discrete segmentation of routes within central London.©Ed Manley |
| Community Detection in Cab Routes in Central London |
|
|
| Exploring more closely the communities in activity formed during 700000 minicab journeys across central London, one can identify how homogenous regions and routes naturally emerge as groups within the dataset. According to this representation, important thoroughfares such as Euston Road, Park Lane and Embankment are represented as distinct clusters, while areas such as Soho, Shoreditch and Kings Cross all occur as individual entities. This demonstrates generally higher levels of movement within these regions than with those areas nearby. ©Ed Manley |
