John A. Miller was one of the few Americans who was puzzled by the construction of elevated highways. “Elevated railways with a capacity of 40,000 persons per hour in one direction are [being] torn down,” he wrote in amazement in 1935, “while elevated highways with a capacity of 6,000 persons per hour are being erected.”

In the 1990s, a bunch of transit planners at Kittelson Associates got the idea of creating "Transit Capacity Manual" that could sit next to the ominous authority of the Highway Capacity Manual, and maybe talk back to it in its own language. The result was the Transit Capacity and Quality of Service Manual. It's quite a technical document, but it does endeavor to explain the main concepts of transit planning and especially its similarities and differences with highway planning. This is useful, because a lot of decisions about transit are made in local and state transportation departments where most people are trained as highway engineers.
The manual is now in its 2nd Edition, and the whole thing is online, here. Kittelson is now starting work on the 3rd Edition, and has set up a web survey asking for input from the profession about how the next version could be improved. If you've used the previous editions at all, or even if you just have strong feelings about what manual should do, you're encouraged to fill out the survey here. I just finished it. It mostly invites you to submit text comment, not just tick boxes, so it's obviously going to be read with some attention.
Greetings from what Australians call "Silly Season," made sillier by the need to roll out all the winter-based imagery of European Christmas at the height of summer.
Over the holiday I will be beavering (as they say in this beaverless country) on the book project, with the help of a great illustration staff.
Expect new content here on January 2. Meanwhile, if you've only recently started reading Human Transit, there's plenty of older but timely stuff to enjoy. Browse for your favorite catgory in the column at right.
And no, this is not my house. Happy holidays.

Every year, Edmonton Transit reduces costs by reducing service during the Christmas holiday season. I’ve no problem with that, but the way it is done is totally user-unfriendly. When you look through that list of changes you quickly realize you have no easy way of knowing when buses are running and if the connections work. Yes, you can use the trip planner, but this kind of thing just defeats the idea of an easy to use network. My eyes glaze over and I think I’d just say “forget it, I’ll drive”.
Personally, I think Edmonton is too surgical with the reductions at the expense of losing the ease of understanding the network. I’m not sure it’s even worth it.
Edmonton Transit certainly has made it complicated, but I respect the imperative behind it. Transit operators are under such constant cost-cutting pressure that they often can't justify running regular schedules on unusual holidays where when demand is higher than a typical weekend day but lower than a full weekday.
Most of the approaches to network planning that I recommend are based on the notion that we need to make networks simpler. Part of that is grouping services into brands of similar usefulness (based on distinctions such as rapid vs. local, peak-only vs all-day, frequent vs not). Doing this, however, requires that a transit agency give up some of its ability to micro-adjust service to its perception of demand. For example, if we specify that the Frequent Network as a whole must be frequent until 9 PM, a few lines that we've included in that category may have to have their evening frequency expanded evne though their ridership then doesn't seem to justify it. That's right: we spend a little and in return we get a network and schedule that we can describe succinctly, and that our customers can remember.
The same principle should ideally apply to these unusual days, though I respect that it's hard to get there. But this kind of standardization, and the clarity that results, are an important frontier for transit if we're going to substantially increase its usefulness, and make people who value freedom choose to rely on it.

Recently I posted on the importance of frequency mapping in network maps. Most transit network maps, I argued, show all the transit lines but make it impossible to sort through them to figure out, quickly, which are likely to be useful. The bottom line: A map that makes all the lines look equally important is as useful as a road map that makes a freeway look just like a dirt road. Continue Reading →
If you want a vivid map of what our friends in Christchurch, New Zealand have been going through, here’s a simple animation of the size, location, and intensity of the ongoing series of earthquakes. It comes by way of friends at NZ in Tranzit, who are also on top of the local transit news.
Quite a bit of damage in the historic urban core. 7.1 was about the magnitude that caused my 1989 near-death experience in Stanford’s Memorial Church, so I can only imagine what it must have been like in Christchurch’s many historic buildings, such as the Art Centre (pictured here in 2005).
HT has a number of readers in Christchurch, including Dave Welch who writes NZ in Tranzit blog, and who may now be regretting his recent over-reliance on earthquake metaphors.
It’s a beautiful city. If you’ve never been there, you should visit. But probably not today.
Hope everyone’s OK, and bravo to everyone’s who’s keeping the city functioning during the emergency.
