04box: on the to-via problem

First, here is a map of the Sydney rail network that may clarify the Lidcombe-Bankstown issue described in Chapter 4.  A train departing Sydney’s Central station with destination “Lidcombe” is probably travelling the orange line, which ends at Lidcombe, instead of one of the lines that’s useful for getting from Central to Lidcombe.  Lidcombe is a final destination, but  the orange line is U-shaped, so what matters at Central is that it goes via Bankstown, not that it ends at Lidcombe.  Lidcombe is the “TO” but in this situation, the “VIA” (via Bankstown) matters more.

Lidcombe bankstown

On the other hand, if you’re considering the orange line from midpoint station such as Marrickville, the “Lidcombe” (TO) matters.  At this point, this  It’s telling you which branch the orange line will follow when it splits at Birrong.  But it’s also telling you, generally, that this train goes westward along the line rather than eastward. 

In signage, transit agencies need to think about whether, at a particular station or stop, the TO and VIA matters more — and if both are needed, which should be emphasized.  For fixed signage at stations, it’s not hard to adjust the content to say what matters from the perspective of that particular station.  If you can’t, do both: “Lidcombe via Bankstown” or even better (at Central) “Bankstown, and on to Lidcombe.”  The latter message properly emphasizes the direction of the train from the point of view of Central, while still signaling the onward path.  This method is almost never used, but there are many situations where it can be useful. 

For signage onboard transit vehicles, the content can now be made responsive to the vehicle’s location, so that signs are automatically updated when the vehicle passes a particular point on the line.  That suggests that bus signs could be more frequently updated to present just the information needed at the stops that it’s passing — which could make for much simpler and clearer signs.

Why care about signage?  Because clear signage makes the system look simpler, and suggests, more directly, that transit is ready to serve your freedom.  And because clarity and accuracy are beautiful.

07box: the new route problem

When the existing transit system doesn’t seem to be meeting the needs of your organization or interest group, it’s tempting to decide that you need a new route, or even a new network.  Service demands are often presented to transit agencies in the form of demands for a new route, and these are sometimes implemented even though they have a weakening effect on the whole transit network.  A good network is a set of services that are all designed to fit together and work together efficiently.  If you just add a route without rethinking the network, you’re almost always reducing the overall efficiency of the network — and thus its ability to get people where they’re going.

If you currently have little or no service, then of course you can demand new service.  But if you already have a transit network and just don’t find it useful for your needs, it’s important to ask whether an investment in that network would help fix the problem, rather than inventing a new service that will duplicate the existing one.

Requests for new duplicative routes often arise where transit service is already running, but:

  • the frequency or span of service is inadequate, or
  • the existing service is hard to figure out, or
  • the existing service doesn’t stop exactly where you want, or
  • the existing service is considered unacceptable in quality for a particular interest group’s needs, or
  • a connection (transfer) is required for the trip that you care about.

Let’s look at each one.  At the end of this article, I’ll also come back to some practical considerations.

Frequency or Span of Service is Inadequate 

If you want more frequency or span (duration) of service, the last thing you want is a new service running on top of an existing one.  Frequency and span are expensive because (except on driverless metros) the cost of driver labor grows directly as you increase either of them.  Running twice as often doubles your operating budget, and so does doubling the number of hours per week that you run.

Operating cost also doubles with the number of route-miles or route-km you have to operate, so fewer routes mean more frequency.  So don’t propose a new route.  Lobby for more frequency and span on the existing one.

The Existing Service is Hard to Figure Out

Some published transit maps showing the entire network are so confusing as to be useless.  Frequent Network mapping is one solution.  But just because you can’t figure out the service doesn’t mean it isn’t there.  Demand that your transit agency create clearer information that makes the usefuless of the service to your community more obvious.  (I can help them with that!)  If your need is for downtown circulation, be sure to study the option of branding existing services as downtown shuttles.  

The Existing Service Doesn’t Stop Exactly Where You Want

If you represent a senior or disabled community for whom walking is a hardship, you probably do need your own route or service, or to be served by existing services — such as paratransit — specialised around those needs.

But if you’re an institution or organization that wants transit to stop closer to your building, a new route is unlikely to be the best solution.  A convention center or university, for example, can ignore the surrounding bus network and create a bunch of its own shuttles, but a whole transit system devoted to one destination isn’t going to be as frequent as what you could have if you worked with the system that exists.  Advocate for stops closer to your location.   

Note, too, however, that if your destination requires a deviation — typically because it’s set back from major streets — then transit can only deviate to you by infuriating everyone else that’s riding at that point.  In that case, depending on how big a market you are, the deviation may well not be justified.  In those situations, don’t invent a large shuttle system that you can’t afford to run frequently.  Instead, offer a really frequent shuttle by running the shortest line possible: a link from your destination to the nearest transit station where versatile service is availble extending in many directions.

Existing Service Quality is Unacceptable

All kinds of emotions get expressed through comments about service quality.  In some cities, for example, everyone is so attached to the idea that buses are only for the poor that the very idea of using the same buses for more diverse markets sounds absurd.  And in such cities, the quality of the bus service may have deteriorated to the point that broadening their market is simply impractical.

On the other hand, many transit agencies are developing the ability to meet customers part way on quality.  Transit service will never be luxurious, but the look-and-feel improvements in the bus over the last 20 years have been truly transformational.  So before you insist that your city’s buses are useless, ride one of the newer ones.  

There are things that you as a civic advocate can do about bus quality to bring it closer to what your constituents need.  You could demand the abolition of bus wraps that cover windows and make interiors gloomy.  You could advocate for a focus on customer experience in purchasing.  Understand that these things cost money, but they may be good long term investments if your view about the inadequate quality of your buses is widely held.  But you’ll get a better mobility out of these improvements to the commons than out of advocating a separate service just for your needs.

Existing Service Requires a Connection (transfer)

Efficient, abundant transit networks often require connections, because you can’t run direct service from everywhere to everywhere else.  This issue is discussed in Chapter 12 of Human Transit, but for a simple case study underlining the futility of new routes designed to avoid connections, see here.

Plan for Versatility

A very frequent transit line — and one that can justify other improvements such as good amenities and transit lanes — is designed for versatility.  It does not serve any particular identified interest group, but instead aims to be useful to many kinds of people for many kinds of purposes.  It does this by running straight, with a reasonable spacing of stops to ensure speed.  It also does this by forming part of an interconnected network.  Remember, it’s not the route that’s designed, but the network.  A route may be designed as it is partly because of how it fits into the larger structure that enables people to get wherever they’re going, not just to destinations along one route.

So if your mission is to serve a whole city or region, designing a transit route around any self-identified group of people is usually a bad idea.  Most successful and attractive transit seeks maximum versatility, by serving the most diverse possible range of demographics, trip purposes, and origin-destination pairs.  You can make exceptions where a single demographic group produces sufficiently massive ridership, as in some commute markets.  But in general, the way people self-organize and self-identify politically is a bad guide to how to meet their transit needs efficiently.  Everyone can draw the perfect transit line just for their interest group, but such proposals tell you nothing about what a good transit system would look like — one that maximized everyone’s ability to get where they’re going.

the car vs. personal technology (quote of the week)

"Previous generations found freedom and flexibility through the car.  But Generation Ys find their freedom and flexibility by staying connected to their friends, family and workplaces through the various information devices – like their laptops, or iphones.

"They can stay connected on a bus or a train. They can bring the office with them. They can bring their study with them. They can bring their friends with them. They can't if they're driving."

— Peter Newman, Curtin University, Perth, Australia, quoted in the West Australian

transit network design: an interactive course

 

Awesome!  Clear and challenging!”

“Well done!  Would like to see this course offering annually, widely advertised to municipal staffs.”

“Excellent instructor.  A lot of information with a high degree of clarity.”

 

On the East Coast? Come to our two-day course in NYC February 6&7, 2014!

 “Transit Network Design: an Interactive Course” is designed to give anyone a grasp of how network design works, so that they can form more confident and resilient opinions about transit proposals.  Any institution or organisation can sponsor the course.  So far, it has been offered through universities, professional organisations, and transit authorities. 

IMG_2816 Much professional training in transit will teach you about quantifying demand, understanding statistics about what transit achieves, studying the features of the various transit technologies, and seeing how transit relates to other goals for governments, individuals, and businesses.  All that is valuable, but there’s a piece missing: Few people get hands-on experience working with transit as a tool, understanding how to use this tool to build a transit network. Learning to think creatively with these tools is the essence of transit planning.

I believe in teaching transit planning the way you’d teach carpentry.  A carpentry class might involve a lecture about the physical structure of wood and how to not kill yourself with a saw, but after that, you’ll only learn carpentry by doing it. 

IMG_2817 The course is a built around a series of exercises where students work together to design transit networks for a fictional city, based on its geography and a set of cost limitations.  The exercises let students learn the basic tools and materials by actually working with them to develop creative solutions to a series of planning problems. 

Issues covered include network design, frequency, right-of-way, basic operations costing, and interactions with urban form.   This course is well suited for professionals, students, community leaders and local government staff. 

The course is done in intensive format covering one or two days. Longer versions can be developed on request. About 60% of class time is in interactive exercises, while most of the rest consists of group discussion based on the results of the interactive work. 

 What Students Have Said

“Jarrett Walker’s two day transit network design class explores the intricacy of designing transit networks, touching on elements ranging from maximizing the utility of a strained, underfunded bus system to planning high capacity bus and rail lines.  This is the kind of modern design that transit agencies should be using to attract new ridership.”  — Mike Cechvala

 “The actual design of the games was fascinating and would be a very useful exercise for any transit system to employ in a variety of situations. — Christopher MacKechnie, publictransport.about.com

“The game format … was great, and it really spurred us to focus on the planning process and understanding the tradeoffs that we were making, and not “force” specific outcomes.”
