Not all Roads are Created Equal: Technical Analysis and Engagement Frameworks developed for New Zealand’s new Speed Management Guide

New Zealand Transport Agency’s new Speed Management Guide introduces two innovative frameworks which together are critical to support local authorities in their efforts to put in place positive and lasting speed management measures. The technical framework provides a single assessment method for determining safe and appropriate speeds at a network level. The technical framework aims to better align travelling speeds with road function, design, safety and use, while linking into wider planning and investment programmes. Implementing speed management interventions is as important as, and much more difficult, than the technical analysis. The new engagement framework builds better conversations on road risk, based on engagement principles that are designed to empower road controlling authorities to improve their engagement, and to encourage communities to participate positively in decision making. This paper presents the application of the technical framework to the Waikato region, including analysis of the assignment and prioritisation of intervention strategies to road sections where speed management interventions have high benefit safety and efficiency opportunities. This paper also details fresh national research focused on understanding community attitudes to speed, used to inform engagement strategies and collateral. This paper will be of interest to all those involved in network management and community engagement, and those interested in prioritising the potential safety benefits of speed management.
