The street lights on Shattuck Ave used to be synced. However, in recent weeks NB and SB Shattuck Ave have been getting backed up with intersections blocked.
NB Shattuck at Bancroft will turn green but Shattuck @ Durant will stay red. As soon as Shattuck @ Durant turns green the signal at Bancroft becomes red. Traffic on NB Shattuck then backs up sometimes blocking the intersection at Durant and even Channing Way.
