Variable Message Signs (VMS) are one of the tools Transit has deployed as part of the Ngauranga Gorge Active Traffic Management System (NATMS). The goal of VMS’s is to influence driver behaviour by giving clear and concise messages to the motorists on traffic conditions. Comprehension of these messages is a key success factor for NATMS. To improve comprehension of its VMS messages, Transit engaged the School of Linguistics and Applied Language Studies of Victoria University to undertake a psycholinguistic investigation of the messages presented on these signs. This paper presents the findings of the Victoria University study only. Transit is yet to evaluate the recommendations of the study.
