## 🌟 Overview

The WIA-AUTO-014 standard defines the comprehensive framework for ride sharing platforms, including matching algorithms, dynamic pricing models, safety protocols, driver/rider verification, and real-time route optimization for shared mobility services.

**홍익인간 (弘益人間) - Benefit All Humanity** - This standard aims to make transportation accessible, affordable, and efficient for everyone while ensuring safety, sustainability, and fair compensation for drivers.

## 🎯 Key Features

- **Intelligent Matching Algorithm**: Real-time passenger-driver matching with multi-criteria optimization
- **Dynamic Pricing Models**: Surge pricing, demand forecasting, and fair fare calculation
- **Safety & Verification**: Comprehensive driver and rider identity verification and background checks
- **Route Optimization**: AI-powered routing for reduced travel time and fuel efficiency
- **Multi-Modal Support**: Integration with public transit, bikes, and carpooling
- **Carbon Footprint Tracking**: Environmental impact monitoring and offsetting
- **Accessibility Features**: Support for riders with disabilities and special needs

## 📊 Core Concepts

### 1. Matching Score Calculation

```
M(d,r) = w₁·D(d,r) + w₂·T(d,r) + w₃·R(d) + w₄·P(r)
```

Where:
- `M(d,r)` = Matching score for driver `d` and rider `r`
- `D(d,r)` = Distance factor (normalized 0-1, inverse of pickup distance)
- `T(d,r)` = Time factor (estimated pickup time efficiency)
- `R(d)` = Driver rating (0-5 normalized to 0-1)
- `P(r)` = Rider preference score
- `w₁, w₂, w₃, w₄` = Weighting factors (sum to 1)

### 2. Dynamic Pricing Formula

```
P = B × (1 + S) × (1 + D) × (1 + T)
```

Where:
- `P` = Final price
- `B` = Base fare (distance × rate + time × rate + base fee)
- `S` = Surge multiplier (0 to 5+, based on demand/supply ratio)
- `D` = Demand coefficient (location-specific premium)
- `T` = Time coefficient (peak hours, events, weather)

### 3. Surge Pricing Model

```
S = max(0, k × ln(demand / supply))
```

Where:
- `S` = Surge multiplier
- `k` = Sensitivity constant (typically 0.5-1.5)
- `demand` = Current ride requests in area
- `supply` = Available drivers in area

### 4. Route Efficiency Score

```
E = (D_optimal / D_actual) × (T_optimal / T_actual) × F_carbon
```

Where:
- `E` = Efficiency score (0-1)
- `D_optimal` = Optimal distance
- `D_actual` = Actual route distance
- `T_optimal` = Estimated time
- `T_actual` = Actual time taken
- `F_carbon` = Carbon efficiency factor

## 🔧 Components

### TypeScript SDK

```typescript
import {
  RideSharingSDK,
  matchDriver,
  calculateFare,
  optimizeRoute,
  verifyDriver
} from '@wia/auto-014';

// Initialize SDK
const rideshare = new RideSharingSDK({
  apiKey: 'your-api-key',
  region: 'us-west-1'
});

// Match driver with rider
const match = await matchDriver({
  riderId: 'rider-123',
  pickup: { lat: 37.7749, lng: -122.4194 },
  destination: { lat: 37.8044, lng: -122.2712 },
  preferences: {
    maxWaitTime: 300, // 5 minutes
    vehicleType: 'sedan',
    accessibility: ['wheelchair']
  }
});

// Calculate dynamic fare
const fare = calculateFare({
  distance: 15.5, // km
  duration: 25, // minutes
  surgeMultiplier: 1.5,
  vehicleType: 'sedan'
});

console.log(`Estimated fare: $${fare.total.toFixed(2)}`);
console.log(`Surge: ${fare.surge}x`);

// Optimize route with multiple stops
const route = await optimizeRoute({
  waypoints: [
    { lat: 37.7749, lng: -122.4194 }, // Start
    { lat: 37.7849, lng: -122.4094 }, // Pickup
    { lat: 37.8044, lng: -122.2712 }  // Destination
  ],
  optimize: 'time' // or 'distance' or 'cost'
});
```

# Calculate fare
wia-auto-014 calc-fare --distance 15.5 --duration 25 --surge 1.5

# Verify driver credentials
wia-auto-014 verify-driver --driver-id driver-456 --check-background

# Optimize route
wia-auto-014 optimize-route --waypoints "37.7749,-122.4194;37.8044,-122.2712"

# Get real-time demand heatmap
wia-auto-014 demand-map --region "san-francisco" --radius 10

# Calculate surge pricing
wia-auto-014 calc-surge --demand 150 --supply 50 --area downtown
