Overview
EN ISO 19134:2008 (ISO 19134:2007) - "Geographic information - Location-based services - Multimodal routing and navigation" defines the conceptual data types and associated operations needed to implement multimodal location-based services (LBS) for routing and navigation. The standard provides a common schema for describing networks, routes, transfers, schedules and cost functions so that mobile clients and web services can plan and navigate journeys that combine two or more transportation modes (walking, driving, transit, taxi, park-and-ride, etc.). It extends ISO 19133:2005 and is intended primarily for web services delivered to wireless devices (including via web-resident proxy applications), though it is not limited to that environment.
Key topics and technical requirements
- Data types and operations: Defines object types and operations required for multimodal routing and navigation (routes, links, junctions, turns, positions, transfers, schedules).
- Multimodal network model: Conceptual schema describing junctions (nodes), directed links (edges), and their topological relationships to represent complex multimodal transport networks.
- Routing and cost functions: Specifies cost function concepts (time, distance, monetary or composite measures) and requirements for additive, non-negative costs used by routing algorithms.
- Service definitions: Describes service types and request/response structures for routing and navigation web services targeted at mobile clients.
- Conformance & testing: Provides conformance classes and an abstract test suite (Annex A) to validate implementations.
- Supporting material: Includes guidance on multimodal cost functions (Annex B) and normative references to related geographic information standards.
Practical applications
- Building multimodal trip-planning engines that combine transit schedules, walking segments and parking/transfer points.
- Implementing LBS web services and APIs for mobile navigation apps, passenger information systems and ITS (Intelligent Transportation Systems).
- Standardizing data exchange between transit operators, GIS platforms and third-party routing providers to ensure consistent routing behavior across services.
- Enabling consistent route cost modeling for optimization (time-based, distance-based or composite cost metrics).
Who should use this standard
- GIS and LBS developers designing multimodal routing engines or navigation services
- Transit agencies and ITS vendors integrating schedules and transfer data
- Mobile app developers and platform providers delivering route-planning to users
- Data modelers and system integrators focused on interoperable geographic information
