Network Coding Standard 2022 Issues remaining to finalize: Table 4.3: Link lengths: Check values. Table 4.5: VDF attributes: Speeds; Capacities. Needs reconciling between NCS16 & GGHM definitions. Table 4.6: Link TYPE: Region codes: I am completely confused about this attribute s definition & usage in the two model systems! Section 4.9: Other link attributes: A precise definition of @toll_zone is required if it is to be included in NCS22. Table 5.1: Transit line name codes (Table 5.1): Needs reconciling between NCS16 & GGHM; Directionality labelling? Table 5.2: Transit vehicle definitions & attribute: Needs reconciling between NCS16 & GGHM. Transit line speeds, TTFs & line segment user fields (us1, us2, us3). Sections 5.3 & 5.5. Tables 5.3 & 5.4. We don t seem to have any standard ttf numbering scheme is this needed? 4

NCS22 Next Steps At a Dec. 9/21 meeting a committee was agreed upon to finalize NCS22. Members: Mauricio Alamillo (MTO), Sundar Damodaran (MTO); Williams Diogu (TMG); Monika Nasterska (Toronto); Norbert Orzel (Mississauga); James Vaughan (TMG). Would like to add Peter Kucirek (Metrolinx). Any other volunteers? Would like to schedule a 1-2 hour meeting this month to finalize the Standard. 8
Multi-Year Work Plan Have been working on a three-year plan: 2022-23 in detail. 2023-24; 2024-25: Planning for & then developing GTAModel V5 9
2022-23 Work Plan Four components: Network modelling improvements. 1. Demand modelling improvements. 2. Routine maintenance & support activities. 3. Preparing for GTAModel V5. 4. 10
Network Modelling NCS16 to NCS22 conversion tools. VDF calibration tools. 2022 base Emme network development. Improved transit travel time modelling. 11
Demand Modelling PoRPoW modelling. Will benefit from ARTM implementation. NWS destination choice modelling. Emissions modelling integration into XTMF/GTAModel. Collaboration with Prof. Hatzopoulou s research group. HOV/carpool modelling. 12
Maintenance & Support Activities Usual, on-going maintenance & support activities: GTAModel V4 maintenance & incremental development. TMG Emme & Aimsun Toolbox Development & Maintenance. XTMF: Upgrades/ Maintenance & V2.0 Development. Documentation of TMG products. Outreach & Training. Meetings: TMGSC & TMGTAC. Big push on XTMF 2 to support GTAModel V5 development. 13
Preparing for GTAModel V5 Largely PhD student & postdoctoral fellow (PDF) based research, supported by TMG staff. Timing is excellent: PhD students finishing their courses in April & ready to dive deep into research work. 2 new PDFs joining the group this spring. Sanjana Hossein (UofT). Lisa Losada Rojas (Purdue). Topics include: Modelling parking demand & supply (Ladan Berahman). Mobility service modelling (Shuoyan Xu; Lisa Losada Rojas; Prof. Shalaby group). NWS modelling (Davia Dong; Sanjana Hossein). TASHA/2 : Activity generation & scheduling modelling (Mohammad Haghighi). Tour-based mode choice (Sanjana Hossein). Employment modelling (Prof. Roorda s group). Demographic modelling / improved population synthesis (Jason Zhang) 14
2023-25: GTAModel V5 Major model system upgrade. XTMF 2 based. TASHA/2 based. 2022 TTS based. Data assumed to be available fall, 2023. Extension to the full GGH. Incorporates new mobility services AV ready . April/22 August/23: Preparatory development of model components using 2016TTS. September/23 March/25: GTAModel V5 development, testing & implementation 15
GTAModel V5, contd The work will draw heavily on the efforts of graduate students & PDFs. TMG will work closely with other UTTRI professors & their research groups: Freight & employment (firmographics): Prof. Matt Roorda. Emissions: Prof. Marianne Hatzopoulou. Transit & new mobility services: Prof. Amer Shalaby. We will be seeking additional funding from other sources (NSERC, Mitacs, etc.). 16
