Francis, the new bus gate is a good insight into the desparation of TFL to make CS9 workBefore a meeting in the business park (outside of course!), I got a coffee from the Italians and spent a few minutes watching it. So there are some key points. The overall green phase for the eastbound junction is a bit over 20 seconds, same as westbound which is sumultaneous, and roughly the same for Acton Lane/ Sutton LaneBut, and its a big but. The lights at the junction go green first, then the new set at the bus gate go green a few seconds later. It then takes a while for the front vehicles to reach the actual junction. So roughly 10 seconds are lost before non-bus traffic can progress through the junection.So we lose roughly half the time for traffic to use the junction. But its even worse, because the bus gate makes traffic queue in a single file, with the left turn filter lane empty. So whereas previously you had a longer left turn filter that was full of traffic, as well as the straight ahead lane full of traffic waiting on red. Now you have traffic needing to filter left or straight on from the single queues.So my non-scientific estimate is around a 60-70% fall in the number of vehicles able to cross in a green eastbound signal.It should not be a surprise I see many more cars and vans turning off the High Road and cutting down onto Wellesley Road. Diverting more traffic onto residential roads and the CS9 route don't seem to matter to TFL, as much as throttling back traffic from the central stretch of the High Road. Also makes it much harder for residents and trade to access north Chiswick.
