In statistics, "average" often means "expected value". No time frame is specified (although you could consider it an infinite time frame). With a small sample size your actual average might not be 10 minutes, but as your sample size grows, it will tend toward 10 minutes. |

If you are talking about spherical-cow style poisson buses, yeah (that's what the author means by "reasonable assumptions). But as the author concludes, bus arrival times are not well modeled by a poisson process.
