For commuters tired of cramped subway and bus rides or paying full fare for a taxi, there are now other options for getting from point A to B. Starting Wednesday, the Taxi and Limousine Commission is rolling out an experimental taxi-sharing program.

At designated stops in Midtown and along East and West 72nd Street, up to four riders can share a ride for $3 or $4 apiece. At first, the ride-shares will only be offered Mondays through Fridays from 6 a.m. to 10 a.m. See the map below for taxi pick-up locations.

New stands are expected to open later this year, including one at LaGuardia Airport. The taxis participating in this program will have specially marked signs.

Below is a map with the pick-up locations.
