S30007 Longitudinal Road Surface Treatments

Consultation undertaken as part of the Road to Zero Harm (RTZH) research project identified gaps in our knowledge related to the effectiveness of a specific set of longitudinal road marking types on safety outcomes (defined below). This work seeks to improve our understanding of how these longitudinal treatments influence driver behaviour, collision likelihood and severity outcomes. It will result in improved estimates of the KSI reductions that could be expected from these treatments on the SRN. The outcome of this work will also provide recommendations for (1) what types of locations to install these markings to have the greatest impact on KPI1 (Reduction in KSIs on the SRN); and (2) how remaining barriers to greater use of these markings could be overcome.
