The data showing how traffic congestion in Cardiff has changed during lockdown

Only a few weeks ago, every morning the streets of Cardiff would be full of traffic as commuters drove across the city. TomTom data shows that congestion in Cardiff has dropped by more than 50% compared with last year. But now, as drivers in the Welsh capital have paused their commute, TomTom shows that traffic has been cut by up to 54% in comparison to last year. This graph shows the latest data from TomTom, comparing current congestion levels to last week and last year, from April 28 to May 5. Car leasing firm Leasing Options recorded the post lock-down traffic at around 8.30am on a weekday in April, (peak travel time for many commuters) and compared this to Google’s historical traffic data from before the lockdown.
