Cycle gates have recently been introduced in London, as a method of separating cycle traffic and general traffic at signal-controlled junctions where a significant proportion of motor vehicles turn left. This report presents the findings of research into road user behaviour and attitudes at two cycle gates on Cycle Superhighways, these being at Queen Street Place and at Lambeth Road. The full report is available online at https://trl.co.uk/sites/default/files/PPR857%20Understanding%20Bicycle%20Movements%20at%20Traffic%20Light%20Controlled%20Cycle%20Gates.pdf
