The same person’s day, played out

0.0 / 21.5 s

In one sentence

Every activity has a place, a start and an end; every trip a mode and a route — that is what the simulation moves through the network.

Why it matters

The simulation moves the person from activity to activity and waits through each one: home until 07:12, walk, bus, work until 16:40, shopping for 33 minutes, home, car to leisure until 21:40, home for the night. The event log on the right is what the simulation records.

Agent-based simulation is usually explained with equations or with a screenshot of a running model. Neither shows why a planner should care. These explainers show the mechanism itself — one person, one day, one score — so that the results on a dashboard stop being a black box.

From a diary record to a simulated day

The strategic model supplies who, what, which zone and which period; the simulation adds exact place, exact time and consistent tours.

A plan scores well when time is spent at activities close to their typical duration — travel is what takes that time away.

The scoring function at work

Travel is judged by what it does to the day — that is what the person compares.
