ICLV model scenario (simulation) analysis
Posted: 13 May 2020, 19:23
Dear Prof. Hess and colleagues,
Thanks for your efforts and help on Apollo modeling. My model is a simple ICLV model that has 4 latent variables (pro-car, pro-bus, env-awareness, and safety) to explain commuting mode choice behavior (car, bus, bike, and walk). In this regard, I have a question regarding ICLV model scenario (simulation) analysis: Based on the manual, I acknowledge how I can simulate change of mode split when, for example, if bus travel time is reduced by 10%.
database$BUS_TIME=(0.9)*database$BUS_TIME
forecast <- apollo_prediction(model, apollo_probabilities, apollo_inputs,
prediction_settings=list(modelComponent='choice'))
However, I'd like to conduct the similar simulation analysis for a latent variable, such as environmental-awareness. (Similar to Section 6 of Hess et al. [2018] paper published in TRA) For example, I'd like to see how the mode choice estimation results may be different if environmental-awareness level of participants in my sample are changed to a certain degree that I'd like to examine.
Could you please provide me with a clue or something how I can conduct this kind of simulation analysis?
Best regards,
Junghwan
