The production of ground-related hazard maps to aid risk management of the Highways England Strategic Road Network Hazard maps for Highways England

Abstract

As part of a coordinated programme of knowledge improvement tasks, Highways England commissioned Mott MacDonald to research, develop and implement a series of maps to communicate clearly the threat posed by ground-related hazards to the Strategic Road Network (SRN) of England. Events associated with a number of hazards have occurred in the recent past. Understanding the presence, and relative likelihood of occurrence, of these hazards over the 7000 km of the SRN is an essential risk management activity. The maps draw on readily available data sources held on the Geotechnical Data Management System of Highways England (HAGDMS) and have been deliberately created to be open and simple, to convey the hazards to users who may not be specialists in engineering geology. This paper presents the development, validation and application of the hazard maps.Thematic collection: This article is part of the Ground-related risk to transportation infrastructure collection available at: https://www.lyellcollection.org/cc/Ground-related-risk-to-transportation-infrastructure
