McIntire/Main adds an extra level of unpredictability, because it is a five-way intersection. Consider the case of a cyclist traveling east on Main into the intersection (a very common occurrence) and stopping at a red alongside motor vehicles. As soon as the light turns green, automobiles may go straight or veer right onto South St. There is no way for the cyclist to gauge this in advance, and it's difficult for motorists to communicate their intentions. The X marks a potential contact point between a turning vehicle and a cyclist going straight.
Bike boxes, technically called an Advanced Stop Line, would set back the line for motor vehicles by a certain distance (recommended 5 meters) and allow cyclists to get a head start on green. Once the cyclist is in full view of motorists, especially larger trucks that have a blind spot for close-up objects beneath them, the chances of a collision are minimized.
