@st_pye @RosamundAdoo_KD @OneCamberwell @outercircles @PaigeLDN__ @RMRsToo @jksmith34 @visitcamberwell @PaulLomax @BHamlets @KingsHeathLTN 1/ When side roads are closed to create #LTNs, some traffic may evaporate i.e. motorists may choose to walk, cycle, use public transport, travel at different time or not travel at all. Experts say around 14% median #trafficevaporation but acknowledge the impact of #coronvirus. 
@st_pye @RosamundAdoo_KD @OneCamberwell @outercircles @PaigeLDN__ @RMRsToo @jksmith34 @visitcamberwell @PaulLomax @BHamlets @KingsHeathLTN 2/ The vast majority of the traffic will find alternative routes including on the boundary roads. This was shown in Waltham Forest LTN with an increase of 3%, 11% and 28% on the boundary roads. We'd likely see a rise on other surrounding roads but sadly they were not monitored.

What we see is an increase in the main road traffic growth for Waltham Forest vs London index from Department for Transport data.

@st_pye @RosamundAdoo_KD @OneCamberwell @outercircles @PaigeLDN__ @RMRsToo @jksmith34 @visitcamberwell @PaulLomax @BHamlets @KingsHeathLTN 4/ There is evidence from Waltham Forest LTN survey of a 1% overall decrease in car usage.
15% increased usage
16% decreased usage
69% stayed the same
There's no evidence this had an impact on reducing LTN car ownership which continues to rise in London. enjoywalthamforest.co.uk/wp-content/upl…
