Discussion Summary
Sign-in and Welcome
- Nate Deshmukh-Towery opened the meeting and went through the housekeeping/agenda items, and with the 2 initial polling questions.
WZDx Updates & News
- Adam Graham highlighted the growth of the WZDx effort through recently compiled metrics.
- Dave Craig presented an update of the WZDx feeds currently available and in development.
Connected Work Zones and WZDx into the Future
- Deb Curtis and Murat Omay discused USDOT's intention to fold WZDx into the standards program and move the WZDx specification to a formal, systems-engineered standard. The effort will be led by the same 50/50 partnership of SAE and ITE that has been leading the Connected Intersections process. Membership of the standardization process will start with the current WZDx stakeholder group.
- Frank Winters asked if USDOT had considered the Open Geospatial Committee as a stakeholder. Deb confirmed that the CTI partners are open to working with anyone.
Specification Update Subgroup Report-Out
- Adam went through the milestones and accomplishments of the subgroup
- Jacob Brady then detailed PRs #278, #281, #291, #294, and #302.
- WZDWG membership/meeting attendees didn't have any comments or feedback on PRs #278, #281, #291, #294, and #302.
- Jacob Larson detailed PRs #304 and #306.
- Nikola Ivanov: Is there any plan to add inner- and outer-loop that exist in TMDD and are frequently used by DOTs managing work zones on beltways?
- Mark Mockett: Yes, we're considering that for the v4.2 short cycle.
- Nikola Ivanov: Is there any plan to add inner- and outer-loop that exist in TMDD and are frequently used by DOTs managing work zones on beltways?
- Skylar Knickerbocker detailed PRs #314 and #322.
- WZDWG membership/meeting attendees didn't have any comments or feedback on PRs #314 and #322.
- Skylar Knickerbocker discussed issues the group plans to address in the next interim release of the specification or through the Connected Work Zones standards process.
Questions
- Nikola: What about adding "operator" or another designation for location method that is designated by TMC operator rather than a device? Currently we default to "other" which works, but isn't ideal.
- Mark: I'm not sure I understand the use case for adding "operator" - the location method property is intended to identify how the geographic coordinates provided for the work zone correspond to its layout. That could mean the first/last point correspond to where traffic control equipment is located, where the first/last signs are located, or the last junction before the work zone.
Specification Extension Subgroup Report-Out
- Weimin Huang presented PR #217 adding vehicle_impact property to the RestrictionRoadEvent
- Brandon Patocka and Eric Kolb presented PR #218 adding a new Road Incident Feed to capture real-time impacts of incidents, disasters, and special events.
Discussion
- Doug Benison: Would you consider combining flood, with wind under a weather category? This way a major snow or ice event can be included as well.
- Eric: From my perspective a flood is more aligned with a disaster than a heavy snow or ice event. I can see a weather category added so that snow and ice can be added under it.
- Alan Clelland: What about Sporting Events?
- Eli: I would urge caution about including sporting events and the like. If you go there, you’ll have to deal with marathons, baseball games and everyhting else that may drift off-schedule.
- Derald: With work zones moving to the standards area, there will be a clear break between work zones and this extension work. As we move toward TDx, answering those questions about how we inform drivers about events is something that can be discussed
- Russell: I suggest combining several of the proposed similar categories (e.g., fair & carnival) unless some utility/value is provided by differentiation.
- Todd Foster: Incident Type (Wind) seems very limited. Why not use Weather to include Flooding, Icy Roads, Heavy Rain/Snow, Low Visibility? It is not obvious as Flooding is located under disaster type, but visibility and road conditions (snow ice) are not addressed
- Jeremy: Traffic info should not be part of WZDx.
- Derald: That's part of why we're breaking it away to TDx. We want to bring people to the right place.
- Jacob B: In past cycles when RoadRestrictionFeed was added - issues were in the WZDx repository, targeted the WZDx specification, etc. Even though the PRs exist in the WZDx repo, they won't be merged into WZDx and will be done on the separate repo. There will be even clearer separation than there is currently.
- Ross: One of the crossing technologies between all of these is the DeviceFeed.
- Siva: If you have questions or comments about TMDD - feel free to forward them. I can help address those through TMDD using two-way communication.
Smart Work Zone Subgroup Report-Out
- Todd Foster reviewed the Smart Work Zone Subgroup's planned activities and milestones.
- Jacob Brady presented the PRs proposed by the subgroup: #228, #266, #267, #273, #292, #293, #308, #309, #310, #311, #312, #313.
- Neil Boudreau discussed issues that the subgroup had discussed but not addressed this cycle: #296, #289, #286, #263, #253, #274, and #187.
- WZDWG membership/meeting attendees didn't have any comments or feedback on PRs or issues.
Worker Presence Subgroup Report-Out
- Ben Acimovic presented on the activities of the Worker Presence Subgroup co-chairs, highlighted by interviews with 13 worker presence data producers and consumers.
- Serge Beaudry discussed outstanding issues for exploration in the Connected Work Zones process: encouraging feedback on the worker presence element of the spec, defining business rules related to data quality, and potentially adding more worker presence devices to the Device Feed.
Technical Assistance Subgroup Report-Out – TA Subgroup Co-Chairs
- Molly Behan presented the activities and milestones of the subgroup and the WZDx-related policy language examples available on GitHub.
- Chuck Felice presented best practices on data security for WZDx feeds such as REST endpoint best practices, using cloude hosted platforms, and securing backend systems.
- Chuck Felice presented the new content and format for WZDx specification business rules.
- Chuck Felice presented a flow chart detailing how data flows from agency or external data sources, through processors, to third parties.
Announcements & Next Steps – WZDWG Co-Chairs
- Nikola: MD will be introducing part time shoulder use that may impact the lane numbering scheme as the lane type will not be consistent depending on time of day or other factors (incidents, events, etc.) What is the experience across the country with part time shoulder use or reversible lane use as it pertains to WZDx? Does WZDx spec account for this?
- Skylar: I don't have a great answer, but here is a link to the example work zone scenarios that includes what you described. Again they are a bit dated as they haven't been updated since we moved to the lane numbering instead of order. https://github.com/usdot-jpo-ode/wzdx/discussions/131
- Chris Brookes shared the link to the Michigan DOT demonstration of a WZDx feed with worker presence information: https://www.michigan.gov/mdot/travel/safety/road-users/work-zone-safety/media
