A new study shows demand for yellow cabs has dropped since the opening of the 2nd Avenue Subway.

A report by the NYU Rudin Center for Transportation shows fewer Upper East Siders who live close to the new stations at 72nd, 86th and 96th streets are hailing yellow taxis.

The study looked at Taxi & Limousine Commission data from the third week of January and compared it to the same time period last year.

It showed yellow cab pickups have fallen by more than 13 percent on average.

Most notably, the eastern end of Lenox Hill had 20 percent fewer pickups, as more people opt for the Q train.

"If we had similar stations all over the city, especially in transit-starved areas like we saw on the eastern end of the Upper East Side, we will see a major improvement in our subway service and we will see a large number of people shifting to transit, instead of taking taxis and for-hire vehicles," said Sarah Kaufman with the Rudin Center.

More than 150,000 riders are now using the new stations on Second Avenue.
