Changes introduced in GRIDSMART 6.3 to better classify short-track u-turns created some false u-turn counts on left turns during congestion, where the exiting left-turn vehicles might become partially or fully occluded. This is resolved in GRIDSMART 6.4, but any false u-turn counts recorded while 6.3 was deployed will remain in your data.
