While I agree with your ultimate point about the trip taking longer, I do disagree with your calculation. For analytical purposes, you have to consider average waiting times, and not any one particular stroke of luck (or lack thereof) as to specific instances. Using your example, in the first case there is three minutes of bus access time, five minutes average waiting time (one-half headway), plus eleven minutes travel time. Total travel time, on average, is nineteen minutes (the actual total travel time will vary between fourteen and twenty-four minutes, depending on the variability of the bus arrival). In the second case there is six minutes of bus access time, but the other times remain constant. Total travel time, on average, is twenty-two minutes (the actual total travel time will vary between seventeen and twenty-seven minutes). Thus, you are correct that total travel time is unnecessarily extended, but the magnitude of additional travel is only three additional minutes--the additional access time--not twelve additional minutes. |
