    • Schedule time tables: exposing static schedule data at the stop level, especially when real-time is not available
    • Multi-modal support: differentiating icons and other customizations to support ferries, light rail, and subway.
    • Status Page and RSS Feed: report on the status and performance of OneBusAway in support of agency transparency goals
    • Last mile support: Integrated with increasingly popular transit services such as bike sharing, Uber/Lyft and others to provide a single point of transit planning.
    • Show the user step-by-step directions for using a bicycle or shared bike. For shared bike, show the user where they can pick up and drop off a bike.
    • Show available bike-share bikes and stations/hubs (if applicable) on a map
  • Status: Proposed / In progress
  • Interested agencies: Sound Transit, HART, MTA, WMATA

Integrated Support for Generating Arrival Predictions

  • Goal: Enhance the capability of OneBusAway to generate arrival predictions from raw vehicle location data
  • Features:
    • Provide custom integrations with the popular open source prediction engine Transitime to support rapid rollout and data synchronizing features.
  • Status: Proposed
  • Interested agencies: WMATA, HART, Sound Transit

Integrate Contributions by various agencies into the OneBusAway project

  • Goal: Merge improvements made by MTA, Sound Transit, and HART on OneBusAway branch into the main OneBusAway project so other agencies/regions can benefit from them
  • Features:
    • onebusaway-admin-webapp: a back-end management module that builds bundles, manages users and API keys, and many other administrative functions (some that are very agency specific).
    • onebusaway-enterprise-acta-webapp: a sample branded web application based off of the MTA Bus Time code base
    • onebusaway-gtfs-archiver: basic support for archiving GTFS and GTFS-RT to a database
    • onebusaway-twilio-webapp: a trivial port of the onebusaway-phone-webapp to Twilio (cloud) services

  • Features:
    • Set a destination reminder for when the rider is approaching their destination and monitor the rider’s location in real-time
    • Allow parents/guardian to be notified if a transit rider deviates from their planned route
    • Support remote real-time tracking of rider if needed by parent, guardian, or travel trainer
  • Status: Proposed
  • Interested agencies: HART, Pierce Transit, Pace Bus

Implementation of Real-Time Dispatching Method

  • Goal: Replace current schedule by a real-time dispatching method
  • Features:
    • Holding times recommended at control point along the route
    • Holding instructions communicated to dispatchers via transiTime extension. Dispatchers then instruct operators when to start their route
    • Dispatching method uses real-time predicted arrivals to maintain stable headways and maximize frequency of service.
    • Predictions are generated by a modified transiTime. transiTime is being modified to provide support frequency based services. This is as a prerequisite to integrating the described holding method into transiTime
    • The predictions will be based on an historical average.
      • Dispatching method will replace schedules during lunchtime (11AM to 2PM) for several weeks
