(Audit 2019) Congestion on major roads during 2016 PM 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 PM peak (4pm to 6pm). 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.

本图层是为《城市交通拥挤与拥堵（Urban Transport Crowding and Congestion）》开展的战略交通建模工作的组成部分，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。

本次数据集反映晚高峰时段（下午4时至6时）的工作日平均交通运行表现。需说明，日流量未达到相关阈值的路网路段未被纳入统计范围，因此部分路段会呈现缺失、断裂或孤立状态。
