There are plenty of good reasons to encourage mass transit, but arguments about the hidden costs of the automobile fall on deaf ears because people, unconsciously or not, factor time and convenience into their decision making. The average driver knows perfectly well why she drives.
The cost of a transportation system is first of all, any flat fare. Call that F. Then there’s a cost per mile (call it C) and the mileage (M). The value of your time we can call S (salary per hour), and the time it takes to travel is T. So we have Cost = F + CM + ST. Time will be mileage divided by your speed (V), so we have Cost = F + CM + SM/V = F + M(C + S/V). We can see that cost increases with mileage (obviously), high time value (every minute traveling costs more) and low speeds.
This is a pretty interesting article, and provides some chewy food for thought. Time = money/happiness. Until mass transit can provide real efficiency, it’s doomed (in addition to many of the other reasons). I am glad that there are people out there who write papers like this.
