许多国家使用某种形式的模式来确定道路使用者收费。卡车预计将支付大部分费用，因为重型车辆是造成道路恶化的主要原因。这项研究记录的结果将最终用于完善新西兰道路使用者收费模式。这项研究是根据长期路面性能项目的数据进行的，其具体目的是确定重型车辆单独加载与加载和环境影响的综合影响相比所造成的相对损害。作为整个研究过程的一部分，进行了聚类分析。分析结果也强调了排水的重要性。聚类分析得出了建议的基于城市或农村位置、交通负荷和气候区域的低容量道路分层。如果需要，这种分层可以用于更详细的用户收费模型实现。在类似的小容量道路上，在气候湿润且土壤条件敏感的地区，车辙率大约高出0.1毫米/年。结果还表明，适当的排水对限制环境影响至关重要。排水系统不完善的道路的车辙率是有排水系统的道路的2.5倍。
Many countries use some form of model to determine road user charges. Trucks are expected to pay for most of the cost because heavy vehicles are responsible for most of the deterioration of roads. This research documents findings that will ultimately be used to refine the New Zealand road user charge models. The research was undertaken on data from the Long-Term Pavement Performance Program with the specific aim of determining the relative damage caused by heavy-vehicle loading alone compared with the combined effects of loading and environmental impacts. As part of the overall research process, a cluster analysis was undertaken. The results from this analysis also emphasized the importance of drainage. The cluster analysis resulted in a recommended stratification of low-volume roads on the basis of their urban or rural location, traffic loading, and climatic area. This stratification could be used for a more detailed implementation of a user charge model if needed. On similar low-volume roads, an approximate 0.1-mm/year higher rut rate was observed in areas that had a wetter climate in combination with sensitive in situ soil conditions. The results also illustrated that adequate drainage was vital for limiting environmental impacts. Roads with inadequate drainage had a rut rate 2.5 times as high as that of roads with the necessary provision for drainage.
