On average, drivers work about nine and a half hours a day, the commission said. That covers the time from a driver’s first pickup to the last drop-off.
That is in contrast to what many cabbies have long told officials: that they often work 11 or 12 hours a day.
The data also shows that the greatest number of cabs are on the road at about 7 p.m. At that time on an average day in February, about 10,000 cabs were cruising the streets. At noon, an average of 8,700 cabs were on the road. The fewest cabs were available at 5 a.m., when about 2,600 cabs were out. ...
Mr. Daus said that drivers’ wages appear to have remained steady at $14 to $16 an hour after expenses.
