Free Delhi NCR traffic simulator
Open the map and start experimenting. No signup required. Sketch road edits, flyovers, underpasses, lane changes and signal ideas, then compare congestion, waiting time, cost, risk and urban mobility trade-offs.
Built for planners, civic-tech builders, students, journalists and Delhi NCR residents exploring traffic congestion ideas before real-world proposals.
Simulation warningExpandCollapse
Traffic Lab is a planning simulation, not an official traffic model, engineering design, legal advice, environmental clearance, construction estimate or government recommendation. It does not factor in many real-world constraints such as detailed origin-destination surveys, signal controller plans, right-of-way litigation, utilities, drainage, geotechnical conditions, emergency access, contractor staging, political feasibility, full induced demand, land acquisition complexity or agency approvals.
Scenario flow
Put a flyover where traffic is choking, then compare the relief.
This preview uses the real simulator screen. The animation highlights the path: pick a corridor, draw a flyover, split traffic onto the new link, then watch the score update.

4Run comparison
The proposed flyover adds capacity over the conflict point, diverts part of the traffic stream, and reduces waiting time instead of just adding random road length.

Scenario editing
Draw roads, flyovers, underpasses and lane changes with start/end clicks; tune flyover approach lanes and roundabout size.
Before/after calculations
Compare speed, waiting time, jams, risk and cost with transparent formulas, reason codes and edit calculation modals.
Open-data first
Uses OpenStreetMap roads, pincode demand inputs and clearly labelled model proxies where observed datasets are not imported.

How the scenario calculations work
Every visible number is documented: OD demand, V/C ratio, waiting time, speed, jams, accident risk, flyover approach-lane effects, open-space shortcut/environment cost, roundabout footprint, land assumptions, mode share, accessibility and city score.
Scenario mechanics
How road edits, OD demand, V/C ratio, waiting time, cost, risk, mode share and scores are calculated.

Model limitations
What Traffic Lab does not factor in yet and why results should be treated as planning estimates.
Disclaimer
Read before using any simulation outputs for presentations, planning or decisions.
Use with caution
Outputs are for exploration and discussion. Validate with qualified transport planners and official datasets before action.
