1
Edit & Validate
Adjust networks, transit lines, and facilities on an interactive map. Built-in checks catch topology errors before they propagate.
Built on MATSim
Model faster. Defend every decision.
CityModeler gives transportation teams a visual workspace for scenario editing, simulation, and result analysis — without sacrificing technical rigor.
Built for agencies. Trusted by consultants. Adaptable for research.
Visual scenario editing
Audit-ready change history
Reproducible model runs
Offline-first desktop app
From Network Edits to Stakeholder-Ready Evidence
Three connected phases. One workspace. No tool-hopping.
2
Run & Compare
Launch simulations, monitor progress, and compare baseline and alternative scenarios side by side.
3
Analyze & Report
Visualize results on the map, generate shareable reports, and export review-ready evidence for decision meetings.
One Workspace. Three Capability Groups.
Everything your team needs from scenario creation to evidence delivery.
Workspace & Editing
Visual Network Editing
Edit links, nodes, and lanes directly on layered maps. No XML hand-editing.
Layer Management
Control visibility and styling across basemaps and modeling layers.
Workbenches
Use focused views for network, transit, facilities, and model runs.
Quality & Control
Change Tracking
Every edit is timestamped and attributed. Export the full history for review meetings.
Scenario Versioning
Branch alternatives, compare outputs, and protect baseline scenarios from accidental overwrite.
Impact Preview
Assess likely effects before applying edits to production scenarios.
Built-in Checks
Surface topology and data issues early with workflow-integrated validation.
Simulation & Analysis
Run Simulations
Start runs, monitor status, and keep execution context in view.
Result Visualization
Explore scenario outputs with map-based and dashboard-ready visual summaries.
Scenario Comparison
Compare baseline and alternatives side by side to quantify tradeoffs.
Analysis & Reports
Generate shareable analysis reports for technical review and decision meetings.
