This paper fills a knowledge gap in helping practitioners determine what is the appropriate design year traffic flow for current and future planning. Analysis of continuous classified traffic data is undertaken with the 10th, 30th, etc hourly flow derived as a percentage of annual average daily traffic (AADT) for typical urban arterial, peri-urban, rural strategic and rural recreational (winter & summer) highways, and the associated percentage of hourly volume (HV) and directional split. The paper outlines the background and methodology, provides example graphs and analysis tables, discusses the results and summarises the key findings. Recommendations are provided for adoption by the NZ Transport Agency (NZTA) in particular and suggestions for further improvement in information management and dissemination of the study results for use by practitioners.
