Problem with right turn filter or indicative arrow signals and signal phasing particularly at tightly physically constrained junctions like this is your own word - 'delay'- to the opposing straight-ahead traffic stream that gets held at a red light while the right turning traffic proceeds on green arrow.Design and operation of signal control of such junctions is a difficult balancing act to give each traffic movement (both vehicles and pedestrians) its fair share of the time-space available, while optimising as far as possible the total traffic throughput through the junction.Take it from me it ain't easy, and there's inevitably much compromise - done plenty of this myself professionally over the decades, despite which wouldn't claim to be a traffic signals expert or specialist.We only belatedly got this essential improvement in safe provision for pedestrians at this junction because we at last got - for all their faults - a breed of transport professional at Ealing Council (and possibly at TfL) that were prepared to look at the matter seriously and diligently and come up with some sort of solution based on what local punters were pushing for with the hard data and evidence we presented - unlike the the previous succession of officers, consultants and local councillors who just threw up their hands and walked away from the problem, leaving pedestrians to fend for themselves - they were/are the real 'idiots'.If you want things freeing up more it'll involve widespread demolition of the fronting buildings to vastly widen the junction, and possibly even construct some awful multilane gyratory traffic system, with consequent devastating effect on the local townscape and environment. If that's what you really want, then don't call us we'll call you.
