Review of questions being asked of the panel:
- SERPM 7.0 uses model parameters for the ABM and related sub‐models borrowed from another region with constants that were calibrated so the model reproduces aggregate targets developed from local data. Please provide guidance to ascertain whether the magnitude of (and change in) the constants is reasonable, guidance to ascertain whether the calibrated model performs well, globally and by submodel/subarea/mode, and, additional tests that need to be performed or presented to better assess its performance. Are there best‐practice benchmarks that the model can be compared against, for example to establish acceptable ranges for trip/tour frequency, trip distance, mode share, etc., elasticities with respect to travel time and travel cost?
- Given the performance and structure of SERPM 7.0 and the data upon which it relies, what data collection and analysis activities does the panel recommend in the short term (next 2 years), medium term (2‐4 years), and long term? With what frequency should the various datasets be collected? Should the next phase of the data collection program be focused on data required to re‐estimate some or all model components, data required to calibrate/validate the model outputs, and/or data required to verify the model inputs? What readily available "off the shelf" datasets have the panel found most useful/reliable in their efforts and which datasets are best collected locally? Please consider all of the major travel markets that the model is expected to address: residential travel, overnight/visitor/seasonal resident travel and truck travel.
