(Audit 2019) Congestion on major roads during 2016 AM peak

This layer is part of strategic transport modelling undertaken for [Urban Transport Crowding and Congestion](https://www.infrastructureaustralia.gov.au/publications/urban-transport-crowding-and-congestion), a supplementary report of the [Australian Infrastructure Audit 2019](https://www.infrastructureaustralia.gov.au/publications/australian-infrastructure-audit-2019).\r\n\r\nThese data represent average weekday transport performance during AM peak (7am to 9am). Note that any network links below relevant daily volume thresholds are not included. This is why some sections will appear missing or broken, and some links are isolated.

本图层属于为《城市交通拥挤与拥堵（Urban Transport Crowding and Congestion）》开展的战略交通建模项目的组成部分，该报告为《2019年澳大利亚基础设施审计（Australian Infrastructure Audit 2019）》的补充报告。
本数据集呈现早高峰时段（7时至9时）的工作日平均交通运行表现。需注意，日流量低于相关阈值的交通网络路段未被纳入统计范畴，这正是部分路段出现缺失、断裂，以及部分路段呈现孤立状态的缘由。
