Ever wondered how busy local traffic junctions are? The charts below show traffic trends for three major local junctions: (1) Vauxhall Gyratory (2) Oval Crossing and (3) Kennington Cross. The Department for Transport does not produce official statistics on how busy such junctions are but this can be estimated from the traffic flows on roads which feed into and out of these junctions. Not surprisingly, Vauxhall Gyratory is the busiest local junction with the Oval Crossing in second place followed by Kennington Cross.
Since 2000, the largest increase in pedal cycle traffic has been at the Oval Crossing which has shown a three fold increase. In constrast, Vauxhall gyratory has seen a modest increase having only doubled. If volume of cyclists is a measure of how busy a junction is then Oval Crossing is some 3/4 of the size of Vauxhall Gyratory. If the current trends continue, it could be as big, at least on this measure, within 10 years.
Of course cycling isn’t the only way to measure how busy a junction. In 2011, there was some 12 times as much motor vehicle as pedal cycle traffic. Unlike pedal cycles, motor traffic has been decreasing. Since 2000, motor vehicle traffic around the Vauxhall Gyratory and Oval Crossing have decreased by approximately one third. A key reason for the reduction of was the London congestion charge which was introduced in February 2003. The impact of the western extension to the congestion charge zone which ran from February 2007 to January 2011 is less clear.

However, this is not the case for road traffic at a local level.”
