Date published: 10 October 2017
You asked
How many junctions in total are there in London's 14,711km road network? I have found figures of 6,300 traffic light sets, however as part of my research at Cardiff University I am also interested in all junctions (including T-junctions and intersection of minor to major roads that do not have traffic lights).
