§ Lord Lester of Herne Hillasked Her Majesty's Government:
Whether they are aware of any data comparing traffic congestion rates in London with those of comparable cities, either in the United Kingdom or in other countries; and, if so, whether they will publish them. [HL442]
§ Lord Macdonald of TradestonThe Department for Transport will shortly be publishing congestion figures that will include estimates for London. Data are also collected in English urban areas other than London, but results are aggregated together across these areas, rather than being published individually, to ensure that they are sufficiently robust. Some work is done in other countries to attempt to quantify congestion in urban areas, but we are not aware of anything that is done on a comparable basis with the estimates that will be published for London.
