GGH Transportation and Growth Plan

[ijmorlan]

I also explain this opinion on a later post. My example was based on taking one bus the entire trip with no transfers.

Everything Dan said, plus, you are still wrong, because even with a single-bus trip the total travel time includes a waiting time on average of one-half the headway. So changing the headway from 30 minutes to 10 reduces the average wait from 15 minutes to 5, a 10 minute savings (on average).

Now of course it’s not quite that simple because, especially at the longer headways, people tend to plan to catch a specific trip, rather than just going to the stop whenever and waiting, but the basic principle is still true.
