This is a problem that’s been nagging me for quite a while. Five years ago I bought a car that was supposed to get whoppingly good gas mileage, and I got to thinking, “At what point is it more efficient to use public transportation?”
Assuming I average 2 trips per day (i.e. to and from work for five days then four trips over the weekend and/or during the week), it would cost me 2x bus fare per day vs. the operating cost of my car.
I could probably look at the number of buses the city has and factor that into the public transportation budget, but I’m really just curious about fuel usage for now: what is the gas mileage of a typical city bus? Put another way, how many people need to be on a bus before it matches a one-person vehicle capable of 30 miles per gallon (i.e. how do the person-miles per gallon differ)?
