TDM – A World Streets Primer

TDM HOV lane

Since TDM (Transportation Demand Management) is a key pillar of the New Mobility Agenda strategy, and of our now forming-up Five Percent Challenge Climate Emergency program, it is important that the basic distinctions are clear for all.  In one of our recent master classes, when several students asked me to clarify for them, I turned the tables instead and asked them, since we are now firmly in the 21st century, to go home, spend a bit of time online and come up with something that answered their question to their satisfaction.  Here is what they came up with, taken whole hog from (which we then lightly edited together and offer for your reading pleasure).

The Cultures of Mobility

What message could a private citizen, an engineer no less, from a small city of a country with barely two million inhabitants send to the Secretary of Transportation of the United States of America? Happily, there is more to transport and social policy than mere size. So if you decide to continue reading, I may have a modest message for you after all.

This evening, 6 February 2009, an interesting event will take place in my city. A thematic event has been organized, dedicated to the “Culture of Mobility”. In this we want to show (again) at the culture of mobility and the culture of the city are one and the same.

Maribor, my beautiful city, the second-largest in Slovenia, is to become the cultural capital of Europe in 2012. Today’s event will start with a documentary film to open up the perspectives of transportation decision-makers in the city of New York, “Contested Streets: a Mobility Tour of Four Great World Cities”. “Contested” takes its point of departure the old habit of automatically building new infrastructure for cars every time a traffic problem arose. The world-famous and world-practiced “forecast and build” culture

TRANSITION TOOLS AND STRATEGIES: Selected Wikipedia checklist of key terms, concepts and references

magnifying glass CLIMATEIntended as a handy research aid, checklist and reminder for students, researchers and others digging into the rich Climate/Mobility nexus and related technical and policy challenges. A certain familiarity with these concepts is desirable; more than that I would say essential.
It is particularly important that those responsible for planning and policy be comfortable with these concepts. Anyone prepared to work in the field will already have familiarity with, say, 9 out of 10 of the concepts identified here. It concerns the stuff of sustainable transport, sustainable mobility and sustainable cities. (I would draw your attention particularly to those entries that are marked with two asterisks * * which touch on some of the more subtle and essential components of a sustainable transport policy.)
From the beginning in the late eighties the New Mobility Agenda was conceived as a shared space for communications and didactic tools zeroing in on our chosen topic from a number of angles, and over the last eight years World Streets has continued in this tradition. I hope that what follows may be useful to some of you. As you will see, I think it is an important and powerful tool — which those of us who care can help shape and put to work for the good cause.

Preparing your next Car Free Day: Check out the fundamentals.

The First Car Free Days Challenge: Toledo Spain, October 1994

Whereas Car Free Days have been organized in cities around the world all over the year for the last two  decades, there is inevitably a spate of high activity in the month of September, much of it the result of the European Commission’s continuing commitment to both the concept of Car Free Days and their own European Mobility Week. And each year we here at World Streets dig into our archives and dust off one or two of the classics as a timely reminder of the fact that the Car Free Day concept has been around and doing its bit since the first international announcement and challenge was made in Toledo Spain on 19 October 1994.

velib-guyWhy do we bother to do this year after year? After all, there is copious documentation and background available at a click, as a quick tour of Google of those three little words yields somewhat more than 55,000 entries, including a fair if distinctly uneven introduction in the Wikipedia article The problem is that most of this material seriously misses the point, and as a result often handicaps cities and groups wishing to organize a Day (a week or month close) to underestimate potential of this approach. The trick is that all of this is quite a simple as it may at first glance appear.

To this end, here we are once again minding the store with the original 1994 article announcing the concept, along with several others from our archives which would appear here in the coming days. A general reference which the reader may find of use is the general introduction which appears here – You will find at the end of this reposting, three separate annexes which provide supplemental background on (Annex A) New Mobility – 1988-1994 Program Summary; (B) Other Tools to Get the Job Done; and (C) a listing of more recent references.

Thinking Exercise: What happens when VKT goes up? Down?

VKT vehilce km miles travel

This flowchart as it stands  gives us a good idea of what happens in today’s dominant mobility pattern in most cities,  where each year the net impact of transport policy (or lack thereof) is to nudge up VKT .  (Actually that should better read MVKT — MOTOR Vehicle Kilometers Traveled , since that brings us right to the main core of the challenge.

Which, if we turn it around and look at it closely, gives us a number of good ideas and targets for our 2020 Five Percent Challenge .  Figure out how to reduce VKT and all sorts of good stuff happens!
