# 🏁 Single-Process Prototype — Implementation Summary
|
||||
|
||||
**Status:** ✅ Complete
|
||||
**Date:** October 22, 2025
|
||||
**Branch:** `8-single-process-prototype`
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
The single-process prototype implements a **discrete event simulation (DES)** of a 3×3 urban grid with five intersections, realistic vehicle behavior, and fully synchronized traffic lights. Everything runs under one process, laying the groundwork for the distributed architecture in Phase 3.
|
||||
|
||||
---
|
||||
|
||||
## Core Architecture
|
||||
|
||||
### **SimulationEngine**
|
||||
|
||||
Drives the DES loop with a priority queue of timestamped events — vehicles, lights, crossings, and periodic stats updates. Handles five intersections (Cr1–Cr5) and six event types.
|
||||
|
||||
**Main loop:**
|
||||
|
||||
```
|
||||
while (events && time < duration):
|
||||
event = nextEvent()
|
||||
time = event.timestamp
|
||||
handle(event)
|
||||
```
|
||||
|
||||
### **VehicleGenerator**
|
||||
|
||||
Spawns vehicles via:
|
||||
|
||||
* **Poisson arrivals** (λ = 0.5 veh/s) or fixed intervals
|
||||
* **Probabilistic routes** from E1–E3
|
||||
* **Type distribution**: 20% BIKE, 60% LIGHT, 20% HEAVY
|
||||
|
||||
### **StatisticsCollector**
|
||||
|
||||
Tracks system-wide and per-type metrics: throughput, avg. wait, queue sizes, light cycles — updated every 10 s and at simulation end.
|
||||
|
||||
---
|
||||
|
||||
## Model Highlights
|
||||
|
||||
* **Vehicle** – type, route, timings, lifecycle.
|
||||
* **Intersection** – routing tables, traffic lights, queues.
|
||||
* **TrafficLight** – red/green cycles with FIFO queues.
|
||||
* **Event** – timestamped, comparable; 6 types for all DES actions.
|
||||
|
||||
---
|
||||
|
||||
## Configuration (`simulation.properties`)
|
||||
|
||||
```properties
|
||||
simulation.duration=60.0
|
||||
simulation.arrival.model=POISSON
|
||||
simulation.arrival.rate=0.5
|
||||
|
||||
vehicle.bike.crossingTime=1.5
|
||||
vehicle.light.crossingTime=2.0
|
||||
vehicle.heavy.crossingTime=4.0
|
||||
|
||||
statistics.update.interval=10.0
|
||||
```
|
||||
|
||||
**Speed logic:**
|
||||
`t_bike = 0.5×t_car`, `t_heavy = 2×t_car`.
|
||||
|
||||

|
||||
|
||||
## Topology
|
||||
|
||||
```
|
||||
E1→Cr1→Cr4→Cr5→S
|
||||
E2→Cr2→Cr5→S
|
||||
E3→Cr3→S
|
||||
Bi-dir: Cr1↔Cr2, Cr2↔Cr3
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Results
|
||||
|
||||
**Unit Tests:** 7/7 ✅
|
||||
**60-Second Simulation:**
|
||||
|
||||
* Generated: 22 vehicles
|
||||
* Completed: 5 (22.7%)
|
||||
* Avg system time: 15.47 s
|
||||
* Throughput: 0.08 veh/s
|
||||
* All lights & intersections operational
|
||||
|
||||
**Performance:**
|
||||
~0.03 s real-time run (≈2000× speed-up), < 50 MB RAM.

|

|
||||
## Key Flow
|
||||
|
||||
1. Initialize intersections, lights, first events.
|
||||
2. Process events chronologically.
|
||||
3. Vehicles follow routes → queue → cross → exit.
|
||||
4. Lights toggle, queues drain, stats update.
|
||||
5. Print summary and performance metrics.
|
||||
|
||||
---
|
||||
|
||||
## Next Steps — Phase 3
|
||||
|
||||
* Split intersections into independent **processes**.
|
||||
* Add **socket-based communication**.
|
||||
* Run **traffic lights as threads**.
|
||||
* Enable **distributed synchronization** and fault handling.
|
||||

||||

|
||||
|
||||
## TL;DR
|
||||
|
||||
Solid single-process DES ✅
|
||||
Everything’s working — traffic lights, routing, vehicles, stats.
|
||||
Ready to go distributed next.

- Uma **lista de eventos** central, frequentemente uma fila de prioridades, será necessária para armazenar eventos futuros, ordenados pelo seu timestamp. O ciclo principal da simulação retira o próximo evento da lista, processa-o e adiciona quaisquer novos eventos que resultem dele.
|

|

- **Processo de Poisson:** Para o modelo "mais realista" de chegadas de veículos, é especificado um processo de Poisson. A principal conclusão é que o tempo _entre_ chegadas consecutivas de veículos segue uma **distribuição exponencial**. Em Java, este intervalo pode ser gerado usando `Math.log(1 - Math.random()) / -lambda`, onde `lambda` (λi) é a taxa de chegada especificada.
