I think the signal cycle is sufficient. The problem is rude commuter pedestrians not considering the possibility of bikes. In my experience bikes are happy to slow or stop when the walk signal is on, but are understandably irked when jaywalkers who can see that no cars are coming proceed without thinking about the bike lanes. We need a "Share the road" sign with bike and pedestrian instead of bike and car, turned 90 degrees and situated in the median. ;-)

I suspect Drwr is mainly concerned about the westbound bike lane? Strictly speaking, that may be Main Street, not sure.

(ah, no, Main Street is just discontinuous)

Thank you for reporting your concern to City of Cambridge via Commonwealth Connect. We have reviewed the information you provided our staff and will be investigating this issue further.

The ongoing construction project at this intersection will include new pedestrian and bicycle signals with improved signal timing. We expect this equipment to be activated this summer.

Thanks for fixing this issue!
