Area Statistics System

Overview

The Area Statistics system provides comprehensive tracking and management of various metrics for park areas, including ride counts, visitor statistics, and historical data. This system enables data-driven insights and performance monitoring at both the area and park level.

Database Structure

Park Areas Table Statistics Fields

ALTER TABLE park_areas ADD (
    -- Ride statistics
    ride_count integer DEFAULT 0,
    coaster_count integer DEFAULT 0,
    flat_ride_count integer DEFAULT 0,
    water_ride_count integer DEFAULT 0,
    
    -- Visitor statistics
    daily_capacity integer NULL,
    peak_wait_time integer NULL,
    average_rating decimal(3,2) NULL,
    
    -- Historical data
    total_rides_operated integer DEFAULT 0,
    retired_rides_count integer DEFAULT 0,
    last_new_ride_added date NULL,
    
    -- Indexes
    INDEX idx_rides (park_id, ride_count),
    INDEX idx_coasters (park_id, coaster_count),
    INDEX idx_rating (park_id, average_rating)
);

Components

1. HasAreaStatistics Trait

Located in app/Traits/HasAreaStatistics.php

Purpose:

• Provides statistics management functionality
• Handles calculations and formatting
• Manages data updates
• Tracks historical metrics

Features:

1. Ride Statistics

   • Total ride count
   • Type distribution
   • Coaster percentage
   • Historical tracking

2. Visitor Metrics

   • Daily capacity
   • Peak wait times
   • Average ratings
   • Formatted displays

3. Historical Data

   • Total rides operated
   • Retirement tracking
   • Last addition date
   • Retirement rate

Implementation Details

Ride Count Management

public function updateRideCounts(array $counts): void
{
    $this->update([
        'ride_count' => $counts['total'] ?? 0,
        'coaster_count' => $counts['coasters'] ?? 0,
        'flat_ride_count' => $counts['flat_rides'] ?? 0,
        'water_ride_count' => $counts['water_rides'] ?? 0,
    ]);
}

Visitor Statistics

public function updateVisitorStats(
    int $dailyCapacity,
    int $peakWaitTime,
    float $rating
): void
{
    $this->update([
        'daily_capacity' => $dailyCapacity,
        'peak_wait_time' => $peakWaitTime,
        'average_rating' => round($rating, 2),
    ]);
}

Historical Tracking

public function recordNewRide(): void
{
    $this->increment('total_rides_operated');
    $this->update(['last_new_ride_added' => now()]);
}

public function recordRetirement(): void
{
    $this->increment('retired_rides_count');
}

Display Features

1. Rating Display

• Star-based visualization (★★★☆☆)
• Numerical rating with one decimal
• "Not rated" fallback

2. Capacity Display

• Formatted numbers with commas
• "riders/day" unit
• Unknown capacity handling

3. Wait Time Display

• Minutes format
• Peak time indication
• Unknown time handling

Data Analysis

1. Distribution Analysis

public function getRideDistributionAttribute(): array
{
    return [
        'coasters' => $this->coaster_count ?? 0,
        'flat_rides' => $this->flat_ride_count ?? 0,
        'water_rides' => $this->water_ride_count ?? 0,
    ];
}

2. Historical Analysis

public function getHistoricalStatsAttribute(): array
{
    return [
        'total_operated' => $this->total_rides_operated,
        'retired_count' => $this->retired_rides_count,
        'last_addition' => $this->last_new_ride_added?->format('M Y'),
        'retirement_rate' => $this->getRetirementRate(),
    ];
}

Performance Optimization

1. Database Indexes

• Compound indexes for common queries
• Efficient sorting support
• Quick statistical lookups

2. Caching Strategy

• Implement statistics caching
• Add cache invalidation rules
• Set up cache warming

Future Enhancements

1. Add seasonal statistics
2. Implement trend analysis
3. Add capacity forecasting
4. Create statistical reports
5. Add comparison tools
6. Implement benchmarking
7. Add historical graphs
8. Create export functionality

Integration Points
