Copenhagen the main routes in and out of the centre have traffic lights working to encourage cyclists to go at a consistent 20km/h or 13mph. They do this by all the lights going green in a coordinated wave. Too slow and you keep missing green lights. Too fast and you keep coming up to red lights. Some lights have count down green LED’s in the road for cyclists to encourage them to catch the green light.

They do this partly to support people cycling. But partly to make cyclists more predictable for other road users.

Transport for London say they can’t introduce this in London. They say to do so they’d have to remove Bus Priority that triggers traffic lights to go green for buses. They also say it would limited their ability to doctor traffic lights to support extra demand. Considering the prize at stake- potentially seeing a leap in cyclist numbers and safety this seems very negative.

Anyone out there who can do the maths to analyse this properly?
