Southbound traffic on 360 going to the Courtyard Tennis Club or residences must wait for left turn arrow onto Courtyard Drive. During the week, between 5 & 7pm is a heavy traffic time due to the number of court times beginning on the half hour for after work play and obviously residents returning home from work. The left turn arrow cycle time is too short to empty the left turn lane and the left turn light skips a cycle every other cycle further exacerbating the frequent overflow onto the median of vehicles waiting to turn. This in turn increases chances of an accident due the number of vehicles pressing through the yellow light. The left turn light duration needs to be increased to empty the lane; and, every cycle should include a left turn light duration.
