TDM – Transportation demand management, traffic demand management or travel demand management (all TDM) is the application of strategies and policies to reduce travel demand, or to redistribute this demand in space or in time.
In transport, as in any network, managing demand can be a cost-effective alternative to increasing capacity. A demand management approach to transport also has the potential to deliver better environmental outcomes, improved public health, stronger communities, and more prosperous cities[citation needed]. TDM techniques link with and support community movements for sustainable transport.
TDM, or Transport Demand Management, has its origins in the United States in the 1970s and 1980s, and is linked to the economic impacts of the sharp increase in oil prices during the 1973 oil crisis and the 1979 energy crisis. When long lines appeared at gas stations, it became self-evident that alternatives to single-occupancy commuter travel needed to be provided in order to save energy, improve air quality, and reduce peak period congestion.
The concepts of TDM borrowed from mainstream transport planning in Europe, which had never been based on assumptions that the private car was the best or only solution for urban mobility. For example, the Dutch Transport Structure Scheme has since the 1970s required that demand for additional vehicle capacity be met only “if the contribution to societal welfare is positive” and since 1990 has included an explicit target to halve the rate of growth in vehicle traffic.
Some cities outside Europe have also consistently taken a demand management approach to transport and land use planning, notably Curitiba, Brazil, Portland, Oregon, USA, Arlington, Virginia, USA,[5] and Vancouver, Canada.
Because vehicle travel was increasing rapidly from 1980–2000, it follows that (with a few exceptions) the techniques of demand management were not widely or successfully applied during this period. Small-scale projects to provide alternatives to single occupant commuter travel were common, but generally were led from outside the mainstream of transport planning. However many of the techniques in the demand management toolbox were developed during this period. (Source: Wikipedia on TDM, lightly edited)

We often hear that sustainable transportation reform is going to require massive public investments, large construction projects, elaborate technology deployments, and above all and by their very nature are going to take a long time before yielding significant results. This is quite simply not true. This approach, common in the last century and often associated with the “American transportation model”, no longer has its place in a competitive, efficient, democratic city And we can start tomorrow, if we chose to.
To get a feel for this transformative learning reality let’s start with a quick look at a first lot of ideas for Slow Street Architecture as a major means for reducing traffic related nuisances, accident prevention and improving quality of life for all. These approaches are not just “nice ideas”. They have proven their merit and effectiveness in hundreds of cities around the world. There is no good reason that they cannot do the same in your city. Starting tomorrow morning.

This is a critical reference and tool set for World Streets readers, introducing the full contents as of 6 March 2019 of the TDM (Transportation Demand Management) Encyclopedia of the Victoria Transport Policy Institute headed by Todd Litman. All the more than one hundred resources and references cited here are available online. The full report is online at: http://www.vtpi.org/tdm/
Transportation Demand Management (TDM, also called Mobility Management) is a general term for strategies that result in more efficient use of transportation resources. This Encyclopedia is a comprehensive source of information about innovative management solutions to transportation problems. It provides detailed information on dozens of demand management strategies, plus general information on TDM planning and evaluation techniques. It is produced by the Victoria Transport Policy Institute to increase understanding and implementation of TDM.
How important is TDM for transport/mobility planners, policy makers or concerned citizens and civil society? It is very easy to answer that question, which boils down to this: If you do not have on your team first rate competence in TDM measures and references, then you are in the wrong business. TDM is the first line of defense of sustainable transport planning and policy!

Dear Colleagues,
The climate agenda is getting high political and media attention worldwide, and there are many important events scheduled for the months immediately ahead. That is good. But in our view the agenda for sustainable transport system reform at all levels is timid, incoherent and in large part irrelevant given the real priorities. Well, what is relevant then? How can we get the level of innovation and reform that is going to be critical in the years immediately ahead?
* * Working draft for peer review and comment of 17 July 2019
</b>The basic concept is simple in principle, namely: to identify and put to work a strategic package of proven, street-tested, cost-effective measures, tools and means to reduce GHG emissions from the mobility sector in a cooperating city or place by a targeted five percent (or better) in a year or less. Realization of the concept on the other hand is highly demanding and requires considerable technical competence, abundant political savvy and leadership by daily example.
The underlying goal is highly ambitious, and perhaps not immediately evident. It is about people and choices, and not so much about infrastructure or vehicles. We are talking here about influencing behaviour of individuals and groups in this specific part of their day to day lives. Since indeed the only way that we can successfully make this critical transition in a functioning democracy — is no less than to change behaviour by creating a transformed urban (or rural, or other demographic) ecosystem of connected realities, time, space, perceptions, awarenesses, values, fears, prejudices, habits and, hopefully in parallel with this an wide array of “better than car” or at least satisficing mobility choices. The key to all this being to offer what are perceived as better choices for all when it comes to daily life, climate, mobility, environment and democracy impacts. The challenge we now face is to accompany this transition, and this in the teeth of a rapidly degrading environment and still a largely skeptical world.
The idea of slowing top speeds on traffic in the city to reduce accidents and achieve other important systemic benefits would seem like a pretty sensible, straightforward and affordable thing to do. For a lot of reasons. Let’s have a look.
Greetings:
What you have here is an independent web platform aimed at two somewhat different but related objectives. For starters . . .
In the first place, you have before you here the full content of World Streets as a collaborative independent “journal of record”, since March 2008 reporting on the winding, often tortuous but often too highly rewarding path toward sustainable transport in and around cities .
Mission: Creating and supporting open, generous, international peer networks to improve our city streets and public spaces for all.
To date: Offering as of early Spring 2019 more than two thousand articles and five thousand illustrative photographs, renderings and graphic image)
Contribution: Is World Streets doing its job? (We asked one hundred of our readers for their views.) And one hundred and one responded: CLICK HERE – http://bit.ly/2tmjZOI
Next Steps: Continue publication of World Streets in its current form, but to refocus its central function over the coming decade to the mobility/climate nexus.

Getting to work in Auckland. Duh! Any clues here?
Since both are key pillars of the New Mobility Agenda and our 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 and asked them, since we are now firmly in the 21st century, to 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 http://bit.ly/2rTxHrr (which we then lightly edited together and offer for your reading pleasure).
