WORKING GROUP SESSION
Spreadsheet list for working session structure
JLathrop: Summarized and described the spreadsheet contents. Ron Ice not here to discuss NA issues. Meaning of PSAPs inside IM domain. Attempt to settle the issues, significant accomplishment.
KBrooke: Led discussion on "scope," identified various
aspects of scope as illustrated in the following table, future work, relationship
to architecture. Use guide or white paper to include work that provides
consideration for the scope issues. JL: Revisions removed most of the scope
considerations. May be part of a program plan or supplemental document.
ASchoka: Guides are appropriate to accompany standards because they are
very high level and cryptic when attempting to apply the standard. Put
in some guidance information and as work progressed, that the material
differs in conformance and informational content from the proposed standards.
Background is useful, but not as part of the standard. [My adaptation
of the table that made sense to me, slightly different from what was on
the board.]

Discussed scope of the EMS effort. LS: TMDD includes 6 or so C2C interfaces. Originally assumed that ere would be a unique set of messages for each interface, with some for the other interfaces. Changed view so that the effort focuses on the dynamic status of the traffic network. Information will be offered at the interface and not a unique set of messages supporting an interface. MS/ETMCC is describes the hierarchy or tree that supports the TMS data flows from the NA. MS/ETMCC draft will be available in June and will incorporate comments and input from the IEEE MST. Moving toward a common set of messages. Presuming that security and data integrity will be handled on a local level. Basically a peer-to-peer level relationships among centers. Use and access issues will be local agreements, assumption is that information will be available, and will be provided on a request basis. No agreement among various groups. A message sets as was done by the data elements. LSaxton: No funded requirement for a guide document. Reasonable amount of concept of operations in the standard, but not how to apply, and briefings are available to understand the work in progress. DKelly: Scope is the collection of dark arrows on the relationship diagram distributed. Can be creative with the flows on the relationship chart.
JL: Some flow developed through WG discussion. Relationship diagram issue of what is covered and what is not by this WG and what is being done by the other groups.
ACTION: look at relationship diagram and identify the work being done by others and there will be more flows based on knowledge of the WG.
Dave Helman DH. NA is evolving. DK: Tie to NA, but get the work done. Recognize that the work needs tog et done, and WG will work on the details as needed. EMark: Feedback to JPO and proposal for next effort. DK: Identified SAE work; CVISN and HAZMAT and MAYDAY. AS: advocates limited the content of the standard, and judgement made about the amount of informative material in the annexes. Relationships to other standards or background, could be included in preface, foreword, etc.
Check web site for documentation. San Antonio URL. www.transguide.tx.us
Table YY in front of standard, XX in informative annex and guide. YY will be reduced to cover the items in the standard. Staple Guide, but not run it through consensus process. Available on the web. ACTION: What is the sense of IEEE to provide the information without formal balloting. NTCIP will be copyrighted, but made freely available. Requirements for IM. Provide information to help reader understand the standard. Tables XX and YY to be discussed later.
Reference source and include entire definition. TMDD will include ID, Name, and Description, and citing NTCIP DE definitions that are not yet defined.
Agreement on the flows between EM and TM, ETS and EM, and Other EM to EM TBD later. Consolidate ETS flows (no messages from PSAP to EM since PSAP is within the EM). What about TMC to TMC? Some covered by TMDD, but a more comprehensive level of detail needed from IM so there will be a TMC to TMC flow.
Architecture flows. Should there be a EM to other EM? EM to ES and TMC. Need to understand what come from the TMC and What should come from EM. TMDD complete list of messages will be available by July. Question of the placement of the ESO in respect to EM.
Should standard include EM to other EM. No. Include as needed, but consider for future work.
Terms and acronyms included are done so because it is used in the document. LS: Assumed that EM data elements would be derived from the IM group. JMona: issues is what is unclear as to what is going to be sent between EM and TM. IM = generic messages, TM = detail messages.
Summary of discussion. TMDD discussion to include all other DDs. TMDD noted that IM has defined generalized message into which data can be added. That was unexpected and expected more explicit identification of IM data and more complete message bodies. MST set of sequence of data elements or data structures will be included in the body of the message. ASN module is a collection of messages. EMS messages will be created that includes legacy systems and that there are many different ways of exchanging information. National reporting systems have some agreements. KB assumes that there a common basis for communication method in real time.
DH: Agreement to get data from different DDs to populate messages. What is the value of leaving it the way it is. ID process, identify recommended set of messages including the data elements. EMark: Presentation on various framework, thoughts behind, and how apply it to a scenario and how the wrap arounds are applied within the scenario.
First step what went into the draft.
Second step to get input from the group to see if the draft is sufficient.
Third step is to populate the messages with the data elements by the WG members.
MO: Cover the technical aspects related to the envelopes. Critical to developing operations and system integration, an important part of the standard. Fleshing out the shells with the data elements. Consider all sources that are important. How it operates. How it would working the real world. AGREEMENT: Look at TMDD as the initial source. Look at use of source in the context of the scenario or data flows.
Message envelopes based on scenarios reviewed. Message context in establishing center. Seen in PSAPs and small towns that have established hours of operations and not manned every hour of every day.
JL provided the background for the draft documents and relationship among the documents distributed.

Different message categories
Top level message types
Status within center
Incident Management define, manage, and hand-off scenario management between centers
Center Management determining if center is on-line or off-line, properties, plans
Routing routing for incident response vehicles, status request of road network,
Asset Management specific to domains and views
Comment regarding information received. RVI and RUI are attributes of DIE? Question about differentiation between IDX and IM msg types. "Close Incident" has different meanings, suggested "Archive" (IS THE CHANGE CONSISTENT WITH TERMS USED)Delete Response from RRP
Comment need for change in terms replacing Green Wave. Priority has different meanings, to include routing of assets and to alternatives for reroute traffic. Room to accommodate. KA: need public traffic diversion. JM: put traffic diversion information could be included in RRP message type. Change in meaning of RRP when Response is deleted.
Comment what happens when plans are changed in the centers. RRP varies, some are procedural. [Response plans is a future] TMCs are not in position to route emergency vehicles. Exchange of information about road network status, question about the difference from the traffic viewpoint and the emergency vehicle viewpoint. Discuss through reflector. Define concept of operations for routing information. Rework section.
Comments eliminate CCTV message type. What happens when an incident commander requests for assets, status of assets, and when asset is no longer available on-scene. Request for asset expand to include assignment and reassignment. IDX message establishes the incident process and context.
LS: explain MS/ETMCC data content example. When available for review, will be made available to IM WG. SK: identified the possibility of having on-scene cameras for video feeds that can be shared or not.
DK: Provided scenario based on an incident in a specific, discussion included adequacy of messages supporting the scenario and potential of implying an architecture that is too specific. Described the role of the IDX message and how it can be augmented as the incident progresses. Assumption and design of messages is to use the IDX as the body within which the incident is described and reported after the incident is fully contained and closed further assuming that there are no long term repair or maintenance on the roadway network. Need more description of the IDX header. Also need a format of the information required for communication with the coroner, etc.
Presentation by TTI ALERT System. Developing test protocols. Need for EMI/RFI testing for combination of equipment to be included in a vehicle or platform.
Where are the data elements? DE will be selected from the TMDD, TCIP, etc.,
80619pm
Next meeting Seattle Sunday Tuesday, August 16-18, 1998. Sunday reserved for coordination among JL, DK, KB, TK, and anyone else interested in attending.
Tentatively schedule following meetings for August, October, and December. ACTION: TK. Check with ITE and AASHTO on budget.
IDX in detail, other messages will be identified.
Steps:
Identify a Center in the field extending their architecture. Address issue and bridge to the next process. ACTION: KB will prepare a White Paper on ITS Emergency Services. Will provide by July 1.
Agreed that the work to be completed by DK/JL within about three weeks and then circulated to the WG for review, complete that draft before the August meeting.
John Lau: Location Reference Information Report. IM needs to pick a profile that is moving forward. Cross-streets maturing, geographic profile more useful for IM domain. Where should the profile work that needs tob e done? Can IEEE do it? Geographic profile home? ISP ATIS vehicle = SAE. ACTION: Ggeographic profile needed for incident management, supports traffic management. Basic input to be from the SAE location reference information report. Impact on State and local jurisdictions and organizational entities involved in mitigating the incident. Develop an information interchange method to described location in multiple ways.
ACTION: TK Send to ITE information about the next meeting, three days in Seattle. Sunday August 16 19, 1998. Proposed to have one more meeting and one more workshop in addition tot he August meeting.
ACTION: KB will provide to DK/JL a description of the IM location data element attributes using ASN.1 notation. Submit to NA and to others.
Draft proposal for new work. On-scene data flows, incident commanders linked, medical, write guide document, response plans, NENA, routing, EMDD. Closure for phase 1.
Location important.
Ed Mark: will provide information about the relative priorities.
