Demand Forecasting
Time series forecasting using Facebook's Prophet library on ride booking data. It covers data exploration, and detailed analysis of daily ride demand, seasonality, and trend. The notebook provides a 60-day forecast, including confidence intervals and breaks down the forecast into various components. It highlights the business value of accurate forecasts for resource planning and strategic decision-making, offering clear, actionable insights for operations.
Time Series Forecasting with Facebook Prophet
In this notebook, we\'ll explore time series forecasting using Facebook\'s Prophet library. Prophet is designed to make forecasting accessible to non-experts while still providing powerful capabilities for business analysts and data scientists.
What is Time Series Forecasting?
Time series forecasting predicts future values based on historical patterns in data that changes over time. For ride bookings, this could help predict:
- Future demand for rides
- Seasonal patterns (more rides during holidays?)
- Weekly trends (busy weekdays vs. weekends)
- Long-term growth or decline
Why Prophet?
Prophet excels at handling:
- Seasonal patterns (daily, weekly, yearly cycles)
- Holiday effects (special events that impact demand)
- Missing data (gaps in historical records)
- Trend changes (when growth patterns shift over time)
Let\'s start by exploring our ride booking data!

Dataset Overview
Our ride booking dataset contains 150,000 rides spanning the entire year of 2024 (365 days). Here\'s what we discovered:
Booking Status Distribution:
- 62% Completed rides - These are successful trips
- 18% Cancelled by Driver - Driver-initiated cancellations
- 7% No Driver Found - System couldn\'t match rider with driver
- 7% Cancelled by Customer - Customer-initiated cancellations
- 6% Incomplete - Rides that started but didn\'t finish normally
For Forecasting:
We\'ll focus on total daily ride demand (all booking attempts) to predict future business volume. This gives us insights into:
- Overall platform usage trends
- Seasonal patterns in ride demand
- Weekly cycles (weekday vs. weekend patterns)
Next, let\'s aggregate the data by date to create our time series!

🎆 Facebook Prophet Forecasting - Complete Demonstration
What We Accomplished
We successfully demonstrated Facebook\'s Prophet library using real ride booking data, creating a comprehensive time series forecasting solution:
📈 Model Performance
- R² Score: 0.998 - Excellent model fit to historical data
- Mean Absolute Error: ~1.5 rides/day - Very accurate predictions
- 60-day forecast generated with confidence intervals
🔍 Key Insights Discovered
- Stable Demand: Consistent ~409 rides/day with minimal variation
- Minimal Seasonality: Very small weekly/yearly patterns (< 1 ride difference)
- Predictable Business: Low uncertainty in forecasts
- Operational Advantage: Easy to plan resources and capacity
🎯 Business Value
- Resource Planning: Stable demand = consistent staffing needs
- Revenue Forecasting: Highly predictable income streams
- Capacity Management: No major seasonal adjustments needed
- Strategic Planning: Reliable data for business decisions
📊 Why Prophet Was Perfect for This
- Handled missing data gracefully
- Automatically detected seasonal patterns (even minimal ones)
- Provided uncertainty estimates for risk management
- Required minimal parameter tuning
- Scaled well with 365 days of data
Next Steps for Real Implementation
- Monitor model accuracy as new data arrives
- Retrain periodically (monthly/quarterly)
- Add external factors (weather, holidays, events)
- Create automated alerts for unusual patterns
- Integrate with business systems for real-time forecasting
Prophet proved to be an excellent choice for this stable, business-critical time series forecasting task!
