As part of an ongoing commitment to improving road safety, Auckland Transport (AT) were looking to make it safer for more children to walk to school on a regular basis. In 2014, they had undertaken an analysis with Interpret and Abley Transportation to assess which of Auckland’s schools had the biggest potential for an increase in walkability. In 2017, this analysis needed to be repeated and expanded to look at walkability across communities.
We expanded upon the original school-based methodology in order to include town centres and transit centres and key walking destinations. For each destination, we determined the number of people accessible on foot within 30 minutes. We also assessed the number of people accessible within a standard risk threshold. Risk was calculated on the network using inputs such as crossing facility type, the number of pedestrians and the vehicle volume. The difference between the number of people accessible within the ‘risk catchment’ and the ‘time catchment’ was used to help assess the potential improvement in walkability for that community.
This analysis provided AT with a prioritised list of communities in Auckland which would benefit from an increase in walkability. AT have subsequently worked with industry partners to identify possible changes in the communities which would increase walkability, such as introducing zebra crossings at key intersections. The model on which the initial analysis was undertaken has been adapted in order to predict the likely effects of these proposed interventions.
