OS MRN Overview

This overview introduces the OS MRN and gives context for all users – highlighting key features, providing examples of potential uses, and listing details such as supply formats, currency, etc.

OS Multi-modal Routing Network (OS MRN) is a fully connected routable network dedicated for the multi-modal routing of people and goods. The product is designed for use in routing applications and contains multi-modal connectivity between Road, Rail, Path, and Ferry networks, brought together by modal change points to enable transition between modes. 

OS MRN was designed and built using the OpenStreetMap schema to facilitate its use in a wide range of routing applications. It takes existing OS network and routing data (available in the OS National Geographic Database – OS NGD) and maps this to the OpenStreetMap schema. New connectivity is added in the form of modal change points, which are key interchange sites where you can transition between different transport modes. Additionally, the dataset contains road restriction information and speed data.
