Often new roads, railways or other transport are presented as ways of improving accessibility but people find that they have the reverse effect. A common example of this is that a new road might speed up some journeys for some people but slow up journeys for others. In order to ensure that land use and transport changes maximise accessibility benefits it is important to plan and deliver accessibility as a managed outcome of investment.
Best practice in planning accessibility has been evolving for decades and in November 2017 Derek Halden was invited by the OECD in Paris to describe the state of the art alongside other experts from across the world. The presentation can be downloaded here.
