Alert me about debates like this

A constituent has written to me suggesting that some London traffic lights could be turned to flashing amber at times when the volume of traffic would not require traffic lights. Will you commit to doing so or, at least, instigating a pilot scheme?

This suggestion would prioritise motor vehicles over people walking and cycling, exactly the opposite of what my Transport Strategy sets out to achieve. Instead, Transport for London (TfL) is currently developing a new traffic light technique called ‘Green Man Authority’ which prioritises pedestrians at traffic lights when vehicle flows are low.

‘Green man authority’ is a radical technique where the traffic signals show a green signal for pedestrians continuously, until vehicular traffic is detected, at which time the pedestrians are stopped on a red signal, and vehicles are given a green light to proceed.

The technique is being tested at ten locations this year and these sites will determine suitability criteria for future locations.
