The lights at this intersection do not meet the demands of the traffic flow. A good example is if you want to take a left from Salem Street (rt 60) onto Fellsway West. The light needs a left turn signal or at least for opposing lanes to not go at the same time.
Currently many cars line up to take the turn (particularly at busy hours), but when the light turns, they immediately have to compete with opposing traffic blocking the turn. The end result is that drivers have no choice but to wait in the intersection and often must wait until the light turns red (and the opposing lane stops) before they can complete their left turn. Only a few cars get by, traffic is impeded, and it presents dangerous conditions. And the chaotic dysfunction encourages people to lose patience and run lights.
