I am here nearly every single day, often multiple times per day, to transfer between 65, 66, 39, E, or D and the automobile compliance with the bus lane is absolutely abysmal. Every single light cycle during rush hour the bus lane is completely blocked by cars and even when there is a Brookline Police cruiser present in the traffic they
do not do a single thing about it. In fact, Brookline Police pulls over speeders and red light runners
into the bus lane in front of Brook House, funneling
all traffic into a single lane, exacerbating the traffic issue. This isnt a one-off occurrence as I've witnessed it 3 times since the weather has gotten chilly and at least a couple times over the summer. This is not helped by the fact that the vast majority of traffic inbound in the morning is trying to go to Longwood, which means taking that left onto Brookline. And what are they accommodated with, only about 230ft of turning queues between poorly synced intersection timings across the three on Rt9. This pushed drivers
into the bus lane because it's the only way around the backup to get into those short left-turn lanes. I've said before how the signal coordination can be changed to accommodate
all traffic not just TSP for buses but an additional lane reconfiguration that would go a long way is eliminating the left-only onto Pearl and making it an extension of the Brookline turn lanes, which would also move more traffic onto the essentially wide open Walnut St to go straight across to Pearl. Doing this would turn what is currently ~370 linear feet of left-turn queue for Brookline into ~1100 linear feet (550 x 2) whilst leaving a lane much clearer as a straight shot through to Huntington and drivers not feeling as much need to encroach on the bus lane.
Roughly done in paint. Blue path shows how much additional queue length there would be for the Brookline Ave turn. Green shows the path to Pearl (where I'd also reroute the 65 inbound to avoid having to dive across all the lanes for a left turn even if a 66 transfer is less smooth). This should all fit within the existing road as long as the bus lane is shifted into the stop, idk why they designed it with space for a bus to bypass another when a bypassing bus could just stay in the normal traffic lane. This would also simplify the Walnut/Pearl signal since it'd only need a shorter left-only cycle for the left onto Walnut from Washington.

Their execution of these bus lanes has been horrendous. No enforcement. Non-existent to barely noticeable TSP. At the very least the bus lanes have been a significant improvement between Huntington and Brookline Ave, and on the outbound side in the Rt9 portion. Delay increases up in Brookline Village are probably from all the school construction. These could have done much more for transportation if they'd done anything other than slap some red asphalt down and call it done.
