Submission to the Raising London Circuit

Why would you add an intersection with traffic lights when the current road configuration provides a more efficient use of an underpass and access routes without lights? We don't need additional traffic lights. The existing solution allows for traffic to flow through the area and access all required routes without the delay that would be created by additional lights. Surely a ramp can be built just for use by the Train (if necessary) and avoid the requirement for the general traffic flow to be stopped by another unnecessary traffic light. Or the train could take a route that results in it joining Vernon Circle or Commonwealth Avenue at an earlier point. This approach would make the train travel time to/from Woden several minutes faster and thus make the train a more attractive transport option than will otherwise be the case.
If the intersection must be added then it should have left turn feeder lanes at each corner to support left turns without the need to wait for the lights. The requirement to wait at an additional set of lights when travelling from London Circuit East to Commonwealth Avenue is also not necessary - why cant you retain the existing left turn feeder lane? The proposed solution will also remove Eastbound access to Parkes Way from vehicles travelling north on Commonwealth Avenue, forcing more vehicles to drive through longer sections of the city and further increasing congestion.
