An equity indicator for urban trip spatial injustice evaluation

In urban context, the use of motorised vehicles tends to be prioritised over other transport categories. This generates an injustice in the distribution of rights, possibilities and mobility freedom. Therefore, it is important to analyse and study disparities among transport users to be able to promote a fair distribution of road spaces with the aim of developing transport systems that offer equal access to public space and opportunities. In this study, we proposed an equity indicator for urban trips with the aim of evaluating spatial injustice in the area under consideration. It is a revised Gini index which aims to show the injustice of the distribution of road space among road users. This methodology was applied to a case study.
