This assessment section includes impacts on security, severance, townscape, accessibility (in the meaning of usability of the transport system for people with physical and hidden disabilities), affordability, etc. It is important to note that non-monetised impacts require the most work and research for improving methodologies in order to better link these impacts to decision-making. This is important for not only essentially influencing whether the investment goes to particular scheme but also to serve as a basis for the adjustment of the scheme design. While improving methodologies for monetising accessibility benefits may help with this in some cases, in others, monetary valuation of accessibility gains - for instance when analysing distributional and spatial impacts - may be unnecessary, as a sole outcome ratio (such as the BCR) could be hiding relevant effects.
