OS Open Roads

OS Open Roads is a high-level view of the road network, from motorways to country lanes in Great Britain. The links represent an approximate central alignment of the road carriageway and include roads classified by the National or Local Highway authority (for example, A Roads) and unclassified roads which make up Great Britain’s road network. Attributes identify the roads that make up the Primary Route Network (PRN) and the Strategic Route Network (SRN). The SRN is made up of nationally significant roads used for the distribution of goods and services, and a network for the travelling public. They are known as Trunk Roads. Whilst the PRN is made up of roads used for transport on a regional or county level and include all roads which make up the SRN.

OS Open Roads 数据集呈现了英国道路网络的宏观视图，涵盖了从高速公路至乡村小道。其中链接代表了道路车道的近似中心线，并包括了由国家或地方公路当局（例如，A 类道路）分类的道路以及未分类的道路，这些道路构成了大不列颠的道路网络。属性标识了构成主要路线网络（PRN）和战略路线网络（SRN）的道路。SRN 由对国家有重要意义的道路组成，用于商品和服务的分配，以及为公众提供交通网络。这些道路被称为干线道路。而PRN则由在区域或县级用于交通的道路组成，包括构成SRN的所有道路。
