Mid-term

The SimMobility mid-term architecture comprises three interconnecting components, namely the Pre-day, Within-day and supply simulators, whose roles are explained here.

Pre-Day

Mid-term preday has two modes of execution - logsum and simulation. All necessary logsums from preday choice models are pre-computed in the logsum mode. The simulation mode uses these pre-computed logsums as it iterates through the system of choice models to build an activity schedule for each individual in the population. The procedure to switch between these two modes is explained here. The inputs required for each of the two modes are listed below.

logsum mode

• population
• zone level inputs

simulation mode

• population
• zone level inputs
• logsums

Within-Day

demand

• day activity schedule
• route-choice related inputs
• supply-withinday feedback tables

supply

• road network
• public transit related inputs
