[quote=Anonymous][quote=Anonymous]why arent there left hand turning signals to mitigate this all together?[/quote] Because on roads that can't be widened for a queue lane you attract queuing which reduces the net throughput of cars - if it is hard to make the turn a lot drivers will figure out alternate ways to get across and never queue up. And in congested areas green time for turn signals comes at the expense of other traffic so in essence it is a zero sum game. On big suburban roads with few pedestrians they can work. In urban areas the trade-offs often don't make sense.[/quote]
