Noah Kazis reports:
"As DOT found in October, while three-quarters of cars were measured speeding before the redesign, now only one in six drive over the speed limit. The number of cyclists roughly tripled on weekdays, and doubled on weekends. There are some slight variations in the December numbers - the more recent data show slightly higher speeds in the morning and slower speeds in the evening, for example - but these effects are looking like they're here to stay."
