Reporting a problem that was fixed by you last winter but has once again no longer responsive. Each morning (0430) over for the last 3 weeks, I have noticed the General Booth London Bridge intersection is no longer responding to actual car locations; instead, the light just rotates thru all four options. Considering majority of the traffic in the morning is turning from General Booth Northern lanes to London Bridge, we find that each morning we have an average of 5 to 6 cars just sitting in the turning lane while the light moves through a standard 1 minute plus exchange. The bad part is sitting there while no other cars are located in the lanes that are green. Request the light return to sensitivity of car location as to assist in transit time and mitigation of wasteful idle time. Once again, you all did a fine job fixing this issue last winter.
