If you think hailing a cab in Philly is difficult, imagine trying to hail one of just seven wheelchair accessible cabs in the entire city.

The scarcity of handicap accessible cabs prompted the Philadelphia Parking Authority to announce a medallion auction that could triple the number of cabs currently cruising the streets.

A total of 150 new medallions will be distributed this year alone, adding to the city's 1,600 medallions. Of those 150, 15 are expected to go to cabs that can accommodate wheel chairs.

Last year, New York City government announced plans to make half of all cabs wheelchair accessible in the next six years. In Philadelphia, less than one percent of cabs can be accessed by those in a wheelchair. After the influx of wheelchair-accomodating taxis in Philly, the share of accessible cabs will increase to a mere 1.2 percent.
