The Challenge

To develop a framework for prioritising Auckland CBD corridors for pedestrian safety improvements using the available information.

The Solution

A priority matrix was developed for Auckland Transport using a combination of the five tier pedestrian hierarchy developed for the Auckland CBD by Abley and the corridor Collective Risk.  The pedestrian hierarchy ranks pedestrian routes based on their strategic priority and their pedestrian presence (measured or estimated pedestrian volumes).  Collective Risk is a measure of the cumulative number of deaths and serious injuries that are anticipated if historic crash patterns continue and is calculated using only those crashes that involve pedestrians.  The High, Medium-High, Medium and Low Medium Collective Risk thresholds are adjusted from those used in the Urban KiwiRAP risk mapping methodology to account for the higher proportion of pedestrian crashes in the CBD.

The Outcome

The 20 highest ranking pedestrian routes in the Auckland CBD were identified.  The ranking is based on the resulting priority matrix and then the number of crashes along the corridor involving pedestrians.  The project report noted that the resulting framework can be enhanced by undertaking pedestrian counts in all higher order pedestrian routes in the CBD to enable the Personal Risk (individual risk) to be calculated for each route.
