That didn’t last long. Last Thursday, less than 24 hours after a mayoral spokesman floated the idea of letting owners of the city’s 68 horse carriage medallions swap them for taxi medallions, Mayor de Blasio reportedly laughed off the notion.
A good thing, too. It’s generally poor policy to buy off one entitlement with another — not to mention dubious politics, given that taxi owners aren’t shy about litigating to protect their turf. Moreover, handing out new taxi medallions looks ill-advised from a traffic standpoint as well. Swelling the ranks of yellow cabs on city streets by as little as one half of one percent (i.e., adding 68 yellows to the current fleet of 13,605) — would have burdened bus riders, car drivers, truckers, and cab users with an estimated $20 million worth of recurring annual delay costs just within the Central Business District (Manhattan south of 60th Street).
That’s the tale told by my Balanced Transportation Analyzer spreadsheet. Longtime Streetsblog readers will recognize the BTA from previous posts covering proposals to toll the entrances to the CBD. But the versatile BTA spreadsheet can assess impacts of lots of other possible changes to the transportation status quo. One such change is adding taxi medallions. Another is eliminating the horse-carriage industry and freeing up CBD road space now occupied by the horses and cabs. Here I look at both.
Taxis first. Using the BTA, I calculate that a mere 68 additional yellow cabs would tack a “time surcharge” of 0.5 percent onto average daytime vehicle travel times across the CBD. Sound trivial? To the contrary, over the course of a full year it adds up to almost 800,000 extra “vehicle-hours” to make the same trips. For users of buses, cars, trucks, and cabs, those hours translate to time costs of around $20 million a year, or nearly $300,000 a year per new cab — $800 per cab per day.
How can just 68 more cabs cause $20 million a year more collective delay? The answer lies in three observations about taxicabs and Manhattan’s Central Business District.
