TrafficSim Intersection App: Advanced Microscopic Traffic Simulation
TrafficSim’s INTERSECTION APP is a groundbreaking online decision-support software for transportation planners and urban policymakers that enables the analysis of any intersection using microscopic traffic simulation. Various traffic control configurations (traffic light control, mandatory right-of-way, right-of-way rule) can be automatically tested under any traffic load.
The system compares variations based on objective criteria such as average speed, traffic volume, or environmental impact, helping to select the infrastructure that is optimal and most beneficial from a societal perspective. This professional road traffic analysis tool radically accelerates the planning process while supporting decision-making for road construction and transportation development projects with accurate data.
By eliminating the need for heavy, desktop-bound legacy software, TrafficSim brings enterprise-grade analysis directly to the browser, offering an intuitive, map-based interface that guides users from network generation to final reporting in minutes.
Core Features & Capabilities
1. Automated Network Generation via Interactive Mapping
Users can simply drop a pin on any real-world location using the integrated OpenStreetMap interface. The system automatically pulls real-world geographic data, generates a highly accurate micro-simulation road network, and identifies the core junction topology, including lanes, lengths, and default priorities.
2. Dynamic Traffic Flow & Routing Configuration
Planners have granular control over the volume and direction of traffic:
- Custom Inflows: Set specific vehicle generation rates (flow) for every incoming edge.
- Turning Ratios: Precisely define where vehicles go using intuitive sliding controls for turning rates. Includes smart "locking" mechanisms.
3. Comprehensive Traffic Control Testing
Rapidly test scenarios by altering the fundamental rules of the intersection:
- Priority & Yield: Toggle right-of-way branches, defining "Main" and "Yield" roads.
- Automated Traffic Lights: Evaluate signaled intersections with auto-generated phase programs.
- Alternative Strategies: Test standard priority, all-way stop, or right-before-left rules.
4. Multi-Faceted Simulation Outputs
Provides the hard data required for modern environmental legislation:
- Traffic Performance: Average speed, queue lengths, and network throughput.
- Emissions Tracking: Precise vehicular emission calculations (CO2, NOx).
- Noise Analysis: Acoustic data (dBA) to understand noise pollution impacts.
5. Visual Data Insights & Heatmapping
Understanding the data is effortless with built-in visual aids. The map dynamically updates post-simulation, applying color-coded heatmaps directly onto the road network. This allows planners to instantly spot bottlenecks, high-emission zones, or excessive noise areas.
6. Automated Report Generation & History
Transforms simulation results into professional, government-ready documents. Users can export comprehensive Word (.docx) reports. Built-in scenario management saves user history, allowing planners to reload previous simulations and run quick comparisons.
