说明

The left turn traffic signal, as you turn into the Huntsville Tennis Center, stays green for 3 seconds and only lets one or two cars through.
It also keeps traffic held on Johnson Road for an very long time (I didn't time that one), even when no one is turning from Jaycee Way or the road opposite onto Johnson Road. In other words, there's no reason for the might to stay red that long, since no one is using it to cross (pedestrians or cars)
Please help! We'd like to arrive to tennis matches on time. :)
