And what's the big difference with these same concepts many of which have been around for decades? It's the technology, stupid! Stay tuned and get involved.

What is xTransit

The job of this section of the WorkPad - placed here to get the discussions and serious work going and with no pretensions of being in any way definitive - is to rough out the main antecedents and eventual raw materials and components of a well working xTransit system. It is being posted at this point as part of the process of starting to define and development useful materials and perspectives on this important and as yet hugely underexploited mobility asset.

If you want to see an example of the sort of thing that we are targeting to provide under this heading, our World Carshare project at http://worldcarshare.com is the best example that we can cite today.

Please give us your comments and suggestions, both as to points of details and more broadly.

xTransit is not:

• Private auto-motive - i.e., not self-propelled or self-driven transport
  • Private cars, privately used (SOV etc.)
  • Motorized two/three wheelers
  • Cycles
  • Walking, running, etc
• Nor traditional "public transport"
  • Rail: metro, conventoinal rail, light rail, tramways. etc.
  • Bus: Fixed route, scheduled services, school buses, etc.

Antecedents/ways of getting around:
In any old order for now and just to get us going. What the following have in common is that they all are, or could be, candidates for, group ride services, more or less well articulated, more or less well supported by SOA technology. For now we cluster these in groups of roughly like concepts and operations:

The other half of the xTransit equation:the logistics link:

• IT/ICT
• Central dispatching services
• Back-office systems and services
• Call centers and processing
• On board information and communications systems
• Advanced traveler information systems
• Internet/website information (may or may not be interactive)
• Internet/website reservation/ordering (interactive)
• Ride matching
• Intelligent Transportation Systems (ITS)
• GPS
• Mobile phones
• Mobility centers
• . . .

The strategic context of xTransit

"How street space is allocated, priced, and managed tells people how to travel".
- Michael A. Replogle, Environmental Defense, 5 Jan 2005 and said right here

A full and proper understanding of the actual context of this thing we are calling xTransit is vital to figuring out what if anything to do next with this concept and way of helping people to get around in our cities, and, yes, small communities as well. Without the context by way of background this is only one more of those many ideas, maybe good, maybe bad, that we can chat about forever and as the damage from the old dysfunctional system continues to mount day after day. But as I hope you know that is not what we are trying to do here at the New Mobility Agenda.

For a pretty good and fairly detailed introductory overview on the overall problematique as we see it, we can refer you to the "Here's our problem" opening section of the Kyoto World Cities 20/20 Challenge at www.kyotocities.org. But in the meantime and with one eye to the clock, what about accepting the following as a rather good surrogate for the rest when it comes to the dysfunctionalities -- thereby putting aside for the moment our very real concerns with pollution, economic costs, health impacts, taxpayer burden and the long list goes on (as you will see if you turn to the full treatment)? But let's simply for the purpose of putting xTransit into perspective think about all this for now as if the only problem that concerns us immediately is that of . . . the (egregious) space requirements of the "old mobility" (that is car-dominated) system.

The key to the New Mobility Agenda in cities lies in what is basically a two pronged approach: (a) aggressive, strategic infrastructure management and (b) parallel creation of a wide range of first class, desirable alternatives to the old mobility system which is now to be gently moved out of the city (or more realistically be greatly reduced in target areas and times), all while being left as a personal option for other transport as people may wish. (Bearing in mind that recent studies provide evidence that Swiss and German city dwellers who get to work and into the center by non-car means, nonetheless for the most part continue to own and use own cars for less dense travel and in the off peak).

The strategy is to withdraw steadily street space from "normal mixed use" and transfer it to more space efficient users, via programs of signage, traffic management, surface treatments and compliance monitoring. And this long list runs all the way from people walking and cycling in safety to traditional scheduled public transport plying fixed routes. That's a beginning, but is not going to be enough in most cities and their environs where the actual pattern of origins, destinations, and times of desired travel has exploded to a point that new means are going to be required to cater to at least a portion of this growing total.

Which is where xTransit in all its varieties comes in: space efficient transport (that in most cases has yet to be fully developed and put into place) that is by dint of load factors a rightful participant user of the new high density streets and lanes.

That's the broad strategic vision; now for the details.

Why has it lagged?

When the first demonstration systems began to appear in the mid/late sixties, most ran into the dual problems of: (a) the technology was not there yet; and (b) insufficiently entrepreneurial skills on the part of the organizers. What was achieved however is that these first systems broke the ice and various groups and people started to look more closely at these group ride, 'third way' concepts.

An even less successful series of attempted innovations -- PRT or Personal Rapid Transit Systems (these entirely off the road, on their own guideways and (too) ambitiously computer controlled from start to finish) -- which despite being the beneficiaries of one, two, even three orders of magnitude more investment also bit the dust. But they too started various players around the world to thinking about high levels of service, and the ways in which new technologies might provide the glue to keep them together.

But the most important barriers that have delayed the progress and on-street introduction of these systems have been above all the result of the many ways in which the old system protects itself form innovation and change. Here are some of these which have been at times examined by researchers, public sector agencies, entrepreneurs, activists, and others hoping to create a more open framework for innovation in this badly constrained sector that is transport in cities.

Which brings us to what is doubtless going to be the most important single target, challenge and eventual contribution:

• "Channeled thinking" on the part of the authorities and most others concerned in shaping the transport context of the city

Next steps

Some of the key issue areas that now need collective attention if xTransit is to advance in time to make a difference, both as a global concept and in its various parts:

• Better knowledge of preconditions for success
• Insitutional, legal, regulatory and other barriers (incl. local ordinances)
• Integration, coordination issues
• Financing: Who pays what
• Role of fairbox
• Integration of fares with other carriers
• HOV priorities
• Labor union (resistance)
• Trade resistance (mainly from taxi operators)
• Insurance, liability
• Safety
• Privacy

The model for our collaborative efforts: Perhaps, until something better pops up, our collaborative efforts over the last decade via the World Carshare Consortium?

It might also be useful to recall that this is an example of what we call a Self-Organizing Collaborative Network, for which you will find further background in the also in-progress Wikipedia entry on this here (own window). You might also wish to have a look at their entry on Knowledge Building, which relates closely albeit without the ever-important component of collaboration for change.
