Carpooling System: A Smart and Privacy-Focused

Ride-Sharing Solution
A Carpooling System enables users to share rides efficiently, reducing travel costs, congestion, and carbon footprints. This
system connects riders and drivers securely while ensuring privacy and convenience. Below is a detailed breakdown of the key
functionalities:

I. Pool Creation & Joining

Creating a Ride Pool (For Drivers)

✅
Drivers can create a ride pool by entering the following details:​

✅
Pickup & Drop Locations – Exact or approximate locations for both starting and ending points.​

✅
Departure Time & Date – When the ride will begin.​

✅
Available Seats – Maximum passengers allowed.​

✅
Vehicle Details – Car model, license plate, and other relevant info.​
Preferences & Rules – Music, smoking, pet-friendly, etc.

🔹 Process:
1.​ The driver posts a new ride with all necessary details.
2.​ The ride becomes visible to nearby users looking for a ride.
3.​ Interested riders can send a request to join.
4.​ The driver can approve or reject requests based on their preferences.

Joining a Ride Pool (For Riders)

✅
Passengers looking for a ride can:​

✅
Search for available ride pools based on their destination and departure time.​
Filter rides based on preferences (e.g., female-only rides, no smoking, etc.).​
✅ Request to join a ride and wait for approval from the driver.​
✅ Once approved, receive ride details, including pickup location and estimated time.
🔹 Benefits:
●​ Reduces individual travel costs.
●​ Helps minimize traffic congestion.
●​ Encourages community-based carpooling.

II. Intelligent Ride Matching

To ensure efficiency, the system automatically matches riders with available carpools based on:

✅ Proximity – Users are matched with ride pools starting near their location.​
✅ Route Similarity – The system finds rides that follow a similar path to the rider’s destination.​
✅ Timing & Availability – Matches only those rides that fit the user’s schedule.​
✅ Preferences & Restrictions – Takes into account user-specific preferences like gender, smoking, pets, and other ride policies.
🔹 Process:
1.​ The system fetches all available rides.
2.​ It compares the ride’s start, destination, and route with the rider’s request.
3.​ Rides are ranked based on best match scores and displayed to the user.
4.​ The rider selects a suitable ride and sends a join request.

🔹 Key Advantages:
●​ Optimized Ride Sharing: Minimal detours for drivers while maximizing seat occupancy.
●​ Efficient Filtering: Riders see only relevant options.
●​ Flexible Matching: Users can choose based on convenience and preferences.

III. Route Matching Percentage

To help users make better decisions, the system calculates the Route Match Percentage, indicating how closely a ride matches
their travel path.

✅ How it Works:
●​ The system analyzes the route planned by the driver.
●​ It then compares this route with the rider’s preferred route.
●​ A percentage score (e.g., 85%) is displayed to show the match level.
●​ Higher percentage rides are prioritized in search results.

🔹 Example:
●​ 100% Match: If a driver’s route perfectly aligns with the rider’s start and destination points.
●​ 75% Match: If the ride covers most of the rider’s route but may require a short detour.
●​ 50% Match: If the ride covers half of the route but requires additional transportation.
🔹 Benefits:
●​ Helps users quickly identify the best-matching ride.
●​ Reduces unnecessary diversions and travel delays.
●​ Improves ride efficiency by optimizing driver-passenger compatibility.

IV. Privacy Protection

Since ride-sharing involves interacting with strangers, privacy is a top priority. The system ensures user safety by masking
personal information.

✅ Phone Number Privacy:

●​ Users can call or message each other via an in-app VoIP system, keeping phone numbers hidden.
●​ Calls are routed through masked numbers (e.g., a temporary number).
●​ The system automatically disconnects after the ride is completed to prevent misuse.

✅ Profile Security:
●​ Users can choose to hide their full name, showing only their first name or initials.
●​ Profile pictures can be blurred until a ride is confirmed.
●​ Only necessary details (such as car model and departure time) are visible to matched riders.

✅ SOS & Emergency Features:

●​ Live Location Sharing – Users can share their ride status with family members.
●​ Panic Button – In case of emergencies, users can alert local authorities.

🔹 Advantages:
●​ Ensures anonymity and protects users from unsolicited contact.
●​ Prevents data misuse and unwanted follow-ups.
●​ Increases trust and security among participants.
