+## ✅ SINGLE-PROCESS PROTOTYPE - COMPLETED
+
+### Phase 2 Status: DONE ✅
+
+All components for the single-process prototype have been successfully implemented and tested:
+
+- ✅ **SimulationEngine** - Priority queue-based discrete event simulation
+- ✅ **VehicleGenerator** - Poisson and Fixed arrival models
+- ✅ **StatisticsCollector** - Comprehensive metrics tracking
+- ✅ **Entry point** - Main simulation runner
+- ✅ **60s test simulation** - Successfully validated event processing and routing
+
+### Test Results:
+- All 7 unit tests passing
+- 60-second simulation completed successfully
+- Generated 22 vehicles with 5 completing their routes
+- Traffic light state changes working correctly
+- Vehicle routing through intersections validated
+
