MetroSim v1.0.0

Operations

Simulation speed Car commute intensity 100%

Higher intensity moves more residents onto the road. Peak compression pulls upcoming departures into a shorter window.

Every run uses the same deterministic seed. Save a baseline first, then compare changed demand, capacity, transit and infrastructure reliability.

Signal timing

Select a signalized intersection on the map.

Transit dispatch

Relief buses target passenger pressure. Signal priority can extend a green phase for a delayed approaching bus. Relief fleet used: 0/6.

Incident response

Active incidents0 Units available3/3

Incidents also occur automatically during the morning. Dispatching a response unit clears them sooner.

Utility operations

Active outages0 Crews available2/2

A feeder outage darkens its powered signals and degrades boarding equipment at affected transit stops until a crew reaches the substation and repairs it.

Water operations

Active outages0 Crews available2/2

Main breaks cut road capacity and pressure. Pump stations depend on their electric feeder, so a grid outage can reduce water service even without a pipe failure.

Replay controls

Recorded timeline 06:30

06:3006:30

Replay is non-destructive: live simulation state is frozen while you inspect recorded snapshots, then restored exactly when you exit.

Click an incident, failed substation, or water outage to inspect it; click a vehicle to inspect its trip, or a signal to tune timing. Drag to pan. Mouse wheel zooms.

v1.0 Objective

Run a large interconnected city, import validated custom city/mod packs, and use deterministic scenarios + replay to understand the result.

No benchmark saved. Run the baseline to 09:30, then compare a modified scenario.

Score combines peak queues, lateness, network speed, transit wait and pass-ups. Deltas compare against the most recently saved baseline run.
