Population
The population data from SimMobility LT is an input for MT preday models. Every individual in the population is a potential source of travel demand. Various characteristics of individuals are used by the preday models to determine their activity schedule.
Population data required for MT is kept within the long-term database in multiple tables viz. individual, household, job, establishment and fm_unit_res tables. See here for a short description of these tables. Below is a list of attributes of each person that MT preday requires to be able to construct an activity schedule.
