Description
Could this bike light be synchronized with the bike light at Cambridge/Quincy for bikes headed south in Quincy St? Right now, when traveling south on Quincy, only the first bike that goes through the Cambridge St intersection can also make it through the light at Broadway. This is a problem because then the other bikes are forced to wait through a full light cycle in a very vulnerable location in the middle of the street while cars traveling East on Broadway turn right onto Quincy and aren’t expecting bikes stopped in the roadway. I think this could be solved by extending the green bike light at Broadway so that all bikes traveling through the Cambridge St bike light have time to clear through Broadway as well. There is already a small overlap, so the Broadway light just needs a few additional seconds added before it goes to red.

The underlying problem is that these very complicated traffic lights with every mode and turning movement getting its own phase will necessarily make everyone wait a lot longer for their few seconds of green. Especially when traffic lights are spaced close together.
If the Quincy/Broadway light got restored to its former simple two-phase timing (green for Broadway, all-way walk, synchronized with the Cambridge Street light), except allowing bikes to go in all directions during the all-way walk, this could solve the problem.

This is a complicated intersection which would likely require simulation to determine an optimal pattern. One factor which is problematic is when a truck or bus is making the right turn from Broadway onto Quincy. When this happens often zero vehicles make it through the Quincy/Cambridge intersection and the phase is wasted due to the time it takes larger vehicles to safely make the turn.
I would agree with others that there seems to be too many phases and patterns which allowed both bike and car traffic to move simultaneously should be considered.
