(Outer Urban PT) Percentage of population within walking distance to high-medium frequency public transport

This is part of analysis from [Outer Urban Public Transport](https://www.infrastructureaustralia.gov.au/publications/outer-urban-public-transport-improving-accessibility-lower-density-areas), which was released in October 2018.\r\n\r\nThis layer presents the proportion of people within walking distance to high-medium frequency public transport stops/stations in 2017. Walking distance is defined as 800 metres for heavy rail, and 400 metres for all other modes. High-frequency public transport is defined as having at least four services per hour during AM peak. This analysis was performed using 2017 timetables.\r\n\r\nSee pages 80-81 of the report for a detailed explanation of methodology.

本分析内容源自2018年10月发布的《郊区公共交通（Outer Urban Public Transport）》报告，完整报告链接：https://www.infrastructureaustralia.gov.au/publications/outer-urban-public-transport-improving-accessibility-lower-density-areas。

本图层展示了2017年步行可达高中频公共交通站点的人口占比。其中，重型铁路（heavy rail）的步行可达阈值设定为800米，其余交通类型的步行可达阈值为400米。高频公共交通的定义为早高峰时段每小时至少开行4班班次。本次分析基于2017年的运营时刻表完成。
