Two issues, really:
(1) It has puzzled me for some time that there is no way to cycle from Brookgate onto Brooklands Avenue. The traffic signal only shows a left green arrow from Brookgate onto Hills Road, which serves the buses, but Brooklands is a major cycle route and would make sense to access it directly from the station (there is a long way around via Clarendon & the busway otherwise).
As it happens, when the left green arrow is showing, I have never seen any other conflicting traffic movement (although presumably Hills Road left onto Brooklands Ave is green at this time? I haven't checked). So it seems like it would be very simple to fix this problem: just convert the green left arrow into a green ball & cut any conflicting movements.
(2) Regardless of that change, there should also be an advanced-stop-line on Brookgate, which there currently is not, so that buses do not sneak up and left-hook people. Even when making a left turn from Brookgate you can be left-hooked by a left-turning bus if they are not careful. So the lack of ASL here is rather strange.
