Except for a July 12 wreck that killed three people and injured six, law enforcement statistics show safety has improved, at least slightly, at Ga. 365 and Howard Road since a traffic light began operating there a year ago today. The number of collisions over a 12-month period ending Oct. 15 was 12, compared to 14 between Oct. 15, 2011, and Oct. 15, 2012, according to Gainesville Police Department numbers obtained by The Times. The number of injuries over the two-year span dropped to 19 from 20 and vehicles involved to 26 from 32.
