Connecting the country – how National Highways are making road journeys safer

National Highways used OS MasterMap Topography Layer, accessible under the Public Sector Geospatial Agreement (PSGA) to create an Auto RedLine.

Overview

National Highways manage a land estate worth over £13 billion – 4,300 miles of Strategic Road Network (SRN) connecting England.

To make sure the SRN, including A roads and motorways, is as safe as possible, National Highways needed a holistic view of the land it’s responsible for.

Challenge

National Highways' GIS and Research Team launched the RedLine Project to produce a digital representation of the SRN’s boundary.

However, manually digitising and evidencing each piece of land using multiple, unaligned datasets was a laborious task.

Solution

National Highways used OS MasterMap Topography Layer, accessible under the Public Sector Geospatial Agreement (PSGA) to create an Auto RedLine.

This automated process combines data to produce a continuous, categorised boundary dataset, providing an accurate and realistic view of the highway boundary, for operational decision-making.

Benefits

With a clear and accurate picture of its total land footprint, National Highways can manage and maintain the network more easily – freeing up time, money, and resource for other projects, keeping goods and services flowing around the country, and, most importantly, making the network safer for people on the roads.
