I would appreciate if anyone can point to any noteworthy studies documenting the impact on traffic flow that avoidable gridlock can have, I would like to contact administrators in my city to get them to consider a public education campaign to teach drivers about turning lanes and pedestrians about walk signals. The combination of these two things means at rush hour we're often lucky if we get 2 cars at a time through a light (1 lane plus turning lane, driver trying to turn leaving his ass in the main lane preventing anyone else from passing, meanwhile pedestrians don't respect walking stop signal, so sometimes the turning driver can't even make it through after the light has turned red as then the main traffic is coming, as they even often have to wait for someone crossing).
