awesome-transit Awesome RSS

Community list of data standards, APIs, apps, tools, datasets, and research around open source technology of public transit.

Open technology provides an opportunity for various stakeholders to collaborate efforts to improve public transit.

Elements of open technology include: - Open standards - Open data - Open source software (both as consumer-facing apps like OpenTripPlanner and developer tools like the GTFS Validator)

This list is focused around the open technology ecosystem for public transportation. Included technologies may be open source themselves and/or rely on open standards and/or open data.

  • Dyno-Demand - A GTFS-based travel demand data format focusing on individual passenger demand suitable for dynamic network modeling developed by San Francisco County Transportation Authority, LMZ LLC, and UrbanLabs LLC.
  • Dyno-Path - (Under development - see this post) Data for individual passenger trajectories.
  • GTFS-plus - A GTFS-based transit network format for vehicle and capacity data suitable for dynamic transit modeling developed by Puget Sound Regional Council, UrbanLabs LLC, LMZ LLC, and San Francisco County Transportation Authority.
  • GTFS-ride - An open, fixed-route transit ridership data standard developed through a partnership between the Oregon Department of Transportation and Oregon State University.
  • GTFS-stat - An extension to a GTFS transit network with additional files that contain performance data developed by UrbanLabs LLC and San Francisco County Transportation Authority.
  • GMNS - General Modeling Network Specification: A format for sharing routable road network files designed to be used in multi-modal static and dynamic transportation planning and operations models. Volpe/FHWA partnership with Zephyr Foundation.
  • GTNS - General Travel Network Specification: A planned data specification for sharing travel demand model networks.
  • IXSI - interface for exchanging information between a travel information system and a sharing system (carshare, bikeshare).
  • MTLFS - Managed and Tolled Lanes Feed Specification: Proposal for a schema that comprise the Managed and Tolled Lanes Tolling Feed Specification (MTLFS) and defines the fields used in all of those files developed by Santa Clara Valley Transportation Authority.
  • MaaS API - A set of open documents and test suite that defines a MaaS-compatible API.
  • NCHRP 08-119 Developing Data Standards and Guidance for Transportation Planning and Traffic Operations - Phase 1 (Anticipated) - The objective of this research is to develop standards and/or guidance to be used and adopted by the transportation community in collecting, managing, and sharing static and real-time data for transportation planning and operations.
  • OMX: The Open Matrix data file format - A structured collection of two-dimensional array objects and associated metadata, for possible use in the transportation modeling industry.
  • OJP - Open Journey Planner.
  • OSDM - Open Sales and Distribution Model: Aims to substantially simplify the booking process for customers of rail trips and to lower complexity and distribution costs for distributors and railway carriers. Contains a specification of an offline model and on-line API. Maintained by the International Union of Railways (UIC).
  • SAE Shared and Digital Mobility Committee - Appears to be working on a data standard for car share and transportation network companies (TNCs) / rideshare.
  • shared-row - A specification for right-of-way (ROW) for a SharedStreets Reference.
  • TCRP G-16 Development of Transactional Data Specifications for Demand-Responsive Transportation (In progress) - The objective of this research is to develop technical specifications for transactional data for entities involved in the provision of demand-responsive transportation. Expected completion date is late 2018.
  • TIDES - Transit ITS Data Exchange Specification (TIDES) is a proposed effort to create standard data structures, APIs, and data management tools for historical transit ITS data including AVL, APC and AFC Data.
