Cobden Junction is the name given to the junction just in front of Mornington Crescent Tube station. In 2013 LB Camden was awarded funding by the GLA under the Mayor's Regeneration Fund for a major scheme to increase the usable pedestrian space and simplify the roads at this busy junction. Camden's designers came forward with a much-improved revised design that exploited a recently-devised signalling scheme ('Hold the Left Turn') to ensure that cyclists were entirely protected from interactions with left-turning vehicles (as outlined in the new London Cycling Design Standards, Section 5.4.5). The full design for Cobden Junction was duly modelled by TfL's network assurance section and was deemed to produce acceptable traffic flows. However at a late stage TfL's traffic signal engineering section vetoed the design and reverted to the original pre-consultation design with only very minimal changes and implementation work went ahead. The construction is very close to completion and the risk of serious injuries or fatalities to cyclists is substantial. Will you now explain why the scheme was vetoed and take remedial action to make the junction safe for cyclists?
