Campaign for Better Transport’s London Campaigner, Richard Bourn said: "The candidates from the main political parties have all said they want to see more walking and cycling. In European cities with the highest levels of walking and cycling, 30kph (or 18mph) limits are the norm. Progressive transport policies and lower speed limits go together. If the Mayoral candidates are serious about promoting walking and cycling they must also sign up to lower speed limits.
"Lower speed limits are also essential for cutting casualties. Research for Transport for London found that fatal or serious injuries to road users were more than halved in areas where 20mph limits had been introduced. But the whole of London deserves safer streets: in 2006, 231 people were killed and 3,715 seriously injured on London’s roads. These figures are unacceptably high."
