Accessibility metrics hold great promise as a means to inform transportation decision-making. Not only do these metrics address the purpose of the transportation system directly – linking travelers to destinations – but they are also infinitely scalable, so they can provide insights at a very granular level. As such, they may be especially useful in evaluating decisions around active transportation facilities, which can be difficult to address in conventional modeling. This white paper investigates a particular issue within active transportation: prioritizing pedestrian improvements to meet ADA standards.
