The SDOs have shown a high level of interest in the ENTERPRISE ITIS message set as they developed standardized traveler and traffic messages. The Society of Automotive Engineers (SAE) considered it for inclusion in the standards they are developing. How they use and develop the message set may impact several projects ongoing in ENTERPRISE states, including CARS, Foretell and AZTech. It was critical for ENTERPRISE to insure that the SDOs understood the messages, their purpose and intended use. Also, it was important for ENTERPRISE to insure that the SDOs understood why ENTERPRISES developed the messages and how ENTERPRISE states are currently using the set. It is in the interest of ENTERPRISE to participate in the standards development process and insure that the SDOs use the messages in a way that is consistent with its original ITIS goals and objectives.
During this project, ENTERPRISE also reviewed the standards development process, and strengthened it by expressing the needs of its members. ITIS-Eye reviewed standards proposed by the SDOs. The review focused on message sets, with an emphasis on insuring all needed messages were included.
This project served as a means for ENTERPRISE to have a direct voice in the SDO processes, particularly with respect to the ITIS message set. It provided ENTERPRISE-directed support to SDOs as they integrated the message set into their standards. The support helped the SDO understand the structure and format of the message sets, and encouraged their adoption in a way that is compatible with its current uses.
ENTERPRISE was also represented at SDO committee meetings. A representative attended meetings and provided feedback to the Board. The representative followed the direction of the Board in its participation in the SDO committees. This representation helped to insure that the intent and purpose of the ITIS message list was achieved as it was integrated into the national ITS standards.
Project Activities
The goal of ITIS-Eye was accomplished through five tasks. These tasks include coordination, meeting attendance, document development and review.
Task 1. Coordination with ENTERPRISE Members
The consultant coordinated with ENTERPRISE members throughout the project and assisted in the coordination of efforts with both the Traffic Management Data Dictionary (TMDD) and the Society of Automotive Engineers (SAE) Advanced Traveler Information Systems (ATIS) SDOs. Throughout the project, the consultant developed technical memorandums that will inform ENTERPRISE of the status of the standards and any expected opportunities and issues related to their development. There was be no less than one technical memorandum delivered to ENTERPRISE after each TMDD and SAE ATIS meeting or major milestone of the monitored standards.
Task 2. SAE ATIS Committee Participation
The consultant provided support to ENTERPRISE members who are members of SDO committees, specifically Stephen Erwin (MTO) and Tim Wolfe’s (ADOT) role with the SAE ATIS committee.
In the support role, the consultant reviewed documents that were produced by the committee and provided comments to the involved ENTERPRISE members. Upon request, the consultant worked with ENTERPRISE to write response papers. These responses have represented the ENTERPRISE position on the issues and may have been submitted by the Board to the SDOs. The decision ton submittal of papers will be at the discretion of the Board.
Task 3. Support RDS Phrases and Data Elements activities
The consultant provided technical expertise and support for the RDS work that ENTERPRISE members were involved in. This support included helping in the development of RDS phrase and data element work.
The support efforts were at the direction of the ENTERPRISE members and included committee document review and developing response papers that represent the ENTERPRISE position.
Task 4. TMDD Committee
The consultant supported ENTERPRISE members during the TMDD Standards Development process. Specifically, the consultant supported Iowa DOT’s activities with the TMDD committee. This support included support at meetings, review of documents developed by the TMDD committee, and developing response papers that represent the ENTERPRISE position.
In addition, the consultant provided support for the further enhancement and development of the Emergency Response Message (ERM) through the committee. To do this, the consultant enlisted members of the emergency response community to provide feedback on the existing and proposed ERM. This feedback was reported to the TMDD committee for consideration.
As the ERM list was developed, the consultant worked with ENTERPRISE to insure that it is coordinated with the larger TMDD. This “harmonization” required the consultant to insure that potential conflicts between message lists are resolved and that one complete list was developed from the TMDD and ERM.
Task 5. ITIS List Standardization
ENTERPRISE took an active role in coordinating the ERM. The ENTERPRISE role was to promote them and insure they were integrated into the TMDD. In order to do this, the consultant used the ERM as the basis for the ITIS Standardized list. The consultant also investigated the need for emergency transit messages which were incorporated into the ERM. The work on the ERM and the potential addition of transit phrases was done in coordination with SAE and TMDD.
Deliverables
- Minute meetings from any SDO meetings at which ENTERPRISE is represented.
- Papers reviewing the SDO documents, including ENTERPRISE responses, and minutes from any relevant SDO meetings or ENTERPRISE conference calls.
- Reviews of documents developed by the TMDD committee, including a response that represents ENTERPRISE’s position, minutes from any meetings or conference calls. An expanded list of ERM messages to be considered for inclusion in the TMDD.
- A complete ERM coordinated with the ITIS list. New and revised terms will be highlighted and presented to the ENTERPRISE Board.
