Taming Manhattan's traffic

In an attempt to eliminate Manhattan's travel inefficiencies and encourage more use of public transportation, Charles Komanoff spent three years creating an Excel spreadsheet (you can download it here) that details "the economic and environmental impact of every single car, bus, truck, taxi, train, subway, bicycle, and pedestrian moving around New York City". Based on that research, he's come up with a plan for changing how transportation is paid for in Manhattan below 60th St. (the CBD or central business district).

It would charge $3 to cars entering the CBD on weekday nights, $6 for most of the day, and $9 during rush hour. The subway fare also varies, but is always less than the $2.25 it is today: $1 at night, rising to $1.50 as day breaks, and peaking at $2 during weekday rush hours. Buses are always free, because the time saved when passengers aren't fumbling for change more than makes up for the lost fare revenue. Komanoff's plan also imposes a 33 percent surcharge on every taxi ride, 10 percent of which would go to the cab driver and the rest to the city.

Komanoff's plan is vastly more sophisticated than a simple bridge toll. Instead of merely punishing drivers, he has built a delicate system of incentives and revenue streams. Just as a musical fugue weaves several melodic lines into a complex yet harmonious whole, Komanoff's policy assembles all the various modes of transportation into a coherent, integrated traffic system.
