GMNS: A Specification for Sharing Routable Road Networks
Building a representation of the transportation network for a travel model is a time-consuming and error prone process. A common network specification will make it easier to share networks and will thus make it easier to leverage existing work and access the most up-to-date information. The General Modeling Network Specification (GMNS) provides a common human and machine-readable format for sharing routable road network files. It was developed under the auspices of the Zephyr Foundation, with support from the Federal Highway Administration (FHWA), and is intended to facilitate the sharing of tools and data sources by modelers. It is designed to be used in multi-resolution and multi-modal static and dynamic transportation planning and operations models with time-varying networks. Its first public release was in January 2020, with several updates since then. This paper describes the specification, including key design decisions, the process for developing it, and the nascent set of tools and projects that are now making use of GMNS.
