Notes

Overview of MDS Release plan

Vehicle Lifecycle #899 - SFMTA

• Adding two new fields in the Vehicles objects: commissioned and decommissioned
  • no discussion, looks good.
• Maintenance came up as a question, regularly scheduled. Vehicle is meant to be more static. Events could get this attached to events - to see when maintenance happened. Could open a new issue to specify agency requirements for maintenance, like lease or own cars. In Policy Requirements - open a new issue.
  • We may talk about this maintenance idea at the next MDS WG meeting. See next issue.
• Tip over is trackable now
• Conditionally Required is defined in spec (was showing Muyi SFMTA branch in call). Here is the link.

Vehicle software/hardware properties #705 - Vianova

• Needs feedback. We may focus on this at next WG meeting because LADOT and Blue Systems are wanting this and have thoughts on a different implementation

Bulk vehicles requests #924 - Populus

• Pierre wondering if this places a burden on implementation with little benefit because you can already get them one at a time. Could support if it there is a more articulated need.
• Needs more feedback and discussion

Event descriptions & passenger pickup/drop off in trips #758 - Netherlands, Populus

• No Event now for this
• Could add to the trip
• passenger_pickup and passenger_drop_off booleans should be added to Trip, where pickup happens at start, drop off happens at end. If more than one passenger or overlapping passengers happen, then these would be separate overlapping trips. See example.

Car share attribute updates #870 - Bergen Norway, Nivel

• All will be optional
• Bike rack is there
• Looks good, anything else to add?

Miscellaneous updates PR#965 - OMF, Blue Systems

• Licensing update, remove custom PR types, link fixes, typos
• Review the latest branch for these and other changes and where the spec stands

Other discussion

• Raphael Dumas - Passenger services state diagram - PTC - private transportation companies. Need passenger wait time. Noted there is a reservation state for this
• reservation cancel/start/stop - clarify in event descriptions. The waiting is happening between stopped and on trip
• stopped state definition seems clear
