## What it is
An interactive JavaScript/HTML5 traffic flow microsimulation web application, the source code behind traffic-simulation.de. It simulates scenarios like ring roads, onramps, and roadworks using car-following and lane-changing models, and can export vehicle trajectory and virtual detector data.

## Use cases
- simulate traffic flow on a ring road in the browser
- study onramp merging and ramp metering effects
- demonstrate phantom traffic jams from roadworks
- export vehicle trajectory data for traffic research
- teach traffic flow dynamics with an interactive tool
- run a ramp-metering game to test control strategies

## When to choose
- you need a browser-based, interactive traffic simulation for teaching or demos
- you want to experiment with car-following and lane-changing model parameters
- you need to generate synthetic vehicle trajectories or detector data without heavy tooling

## When to avoid
- you need large-scale, high-performance network simulation of real road networks
- you require SUMO-level features like multi-modal traffic or signal control
- you need a headless simulation server or Python/C++ integration

## Facets
- artifact type: application
