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: 

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!

Author’s Preface: from on Affordable Transportation 
I can report from personal experience that affordable transportation is possible and beneficial, but requires appropriate transport planning. Our demographically average household (two parents, two children, dog and cat) owned just one car, and five years ago when its engine failed we became car-free. We now rely on a combination of  walking, cycling, public transport, taxi, delivery services and occasional vehicle rentals. We spend less than $2,000 annually on local transport, at least $5,000 less than peer households. These savings finance our children’s university educations, and using affordable modes provide other benefits including increased personal fitness and better interaction with neighbors.
These savings and benefits are possible because we live in a compact community that has relatively good walking and cycling conditions, good public transit and taxi services, and local stores that offer delivery services. Conventional transport planning overlooks these benefits. Conventional planning tends to favor faster but less affordable transport modes, such as automobiles, over slower but more affordable modes such as walking, cycling and public transit. More comprehensive and multi-modal planning can allow other households to share the benefits we enjoy
