| * | Streetcar | Average Earthling | OECD/IEA 2005 - Saving Oil in a Hurry | Global: All () | 34.84 | persons / vehicle | To calculate this value we first averaged the tram seat occupancy of the four regions listed. We then assumed that there are 52 seats on a tram (this is the number of seats on a M5000). We multiplied the average seat occupancy by the number of seats to get this value. |

We then assumed that there are 68 seats on a metro (this is the number of seats on a Breda 3000-Series). We multiplied the average seat occupancy by the number of seats to get this value. |
| * | Subway | Average New Yorker | NYMTC 2009 - Regional Transportation at a Glance 2007 | New York City: Urban landscape (2007) | 28.456 | persons / vehicle | This value was computed by dividing the passenger miles traveled by the vehicle miles traveled for total rail rapid transit in 2007. |

| * | Taxi | Average American | Summary of average auto trip occupancy from NHTS 2009 | US: All () | 2.0302 | persons / vehicle | We added the three taxicab sums of weighted travel day records (WTTRDFIN) in order to compute the total number of trips by taxicab. Next we computed the total number of persons who traveled by taxicab by multiplying each of the three trip occupancies of taxicabs with their corresponding sums of WTTRDFIN. We then divided the total number of persons by the total number of trips to receive the vehicle occupancy value. |

| * | Train | Average Earthling | OECD/IEA 2005 - Saving Oil in a Hurry | Global: All () | 46.46 | persons / vehicle | To calculate this value we first averaged the suburban rail seat occupancy of the four regions listed. We then assumed that there are 101 seats on a tram (this is the number of seats on a M7). We multiplied the average seat occupancy by the number of seat to get this value. |
| * | Train | Average New Yorker | NYMTC 2009 - Regional Transportation at a Glance 2007 | New York City: Urban landscape (2007) | 36.726 | persons / vehicle | This value was computed by dividing passenger miles travled by vehicle miles traveled for total downstate suburban rail. |
| * | Train | Eco-conscious | NYMTC 2009 - Regional Transportation at a Glance 2007 | New York City: Urban landscape (2007) | 36.726 | persons / vehicle | We are assuming the same train occupancy as Average New Yorkers for this lifestyle. We computed this value by dividing the passenger miles traveled by the vehicle miles travled for total downstate suburban rail. |
