**Title:** *Drivers can’t find parking* → **Software Solution: Smart Parking Finder Web Application**
*Submitted in partial fulfillment of the requirements for the Bachelor of Information Technology (BIT) – External Degree Programme, University of Moratuwa*

## **1. Introduction**
### 1.1 Problem Statement
In urban areas of Sri Lanka—especially Colombo, Kandy, and major university towns—**finding available parking is a daily frustration** for drivers. Key issues include:
- **No real-time visibility** into parking availability; drivers circle blocks wasting time and fuel.
- **Manual parking lots** with no digital occupancy tracking.
- **Unpredictable pricing** and unclear operating hours.
- **Overcrowding** at commercial zones during peak hours, while nearby private or underused lots remain empty.
- **Illicit parking** on sidewalks or roads due to lack of alternatives, causing traffic congestion.
- **Tourists and visitors** struggle to locate legal, safe parking near malls, hospitals, or campuses.
This leads to:
- Increased traffic congestion and pollution,
- Lost productivity and customer dissatisfaction,
- Revenue loss for parking lot owners due to low utilization,
- Safety and legal risks from illegal parking.
### 1.2 Proposed Solution
A **web-based Smart Parking Finder Application** that aggregates real-time and scheduled parking data from public, private, and commercial lots, enabling drivers to:
- **Search** for nearby parking spaces by location or destination,
- **View real-time availability** (where sensors exist) or **predictive availability** (based on historical/reservation data),
- **Compare pricing, operating hours, and amenities** (e.g., CCTV, EV charging, covered),
- **Reserve a spot** (optional for partnered lots),
- **Navigate directly** via integrated maps,
- **Receive reminders** before reservation expiry.
The system is designed for **low-infrastructure environments**—supporting both **sensor-enabled lots** and **manual/admin-updated lots**—making it practical for Sri Lankan adoption.
---
## **2. Objectives**
- Reduce time and fuel wasted searching for parking.
- Increase parking space utilization through better visibility.
- Provide a unified platform for public, private, and commercial parking providers.
- Enable small parking lot owners to digitize operations with minimal cost.
- Improve urban mobility and reduce congestion.
- Deliver a scalable, deployable system for Sri Lankan cities and university campuses.
---
## **3. Scope**
### 3.1 In Scope
- **Web application** (mobile-first, responsive) for drivers and parking lot administrators.
- **Driver features**:
- Search parking by current location or destination (e.g., “near Colombo Fort” or “University of Moratuwa”).
- View real-time or estimated availability.
- Filter by price, distance, covered/uncovered, EV charging, security.
- See operating hours, contact info, and user ratings.
- Reserve a spot (for lots that support booking).
- Get turn-by-turn navigation (via Google Maps link).
- Receive SMS/email reminder 15 mins before reservation ends.
- **Parking Admin Portal**:
- Register lot (name, location, capacity, pricing, photos).
- Update real-time availability manually (e.g., “12/20 spots free”).
- Enable/disable reservations.
- View booking history and occupancy analytics.
- **Admin (System) Dashboard**:
- Approve/reject parking lot registrations.
- Monitor platform usage, popular zones, uptime.
- **Offline-Friendly Design**: Cache recent searches; allow basic use with low connectivity.
### 3.2 Out of Scope
- Hardware installation (e.g., IoT sensors, cameras)—system assumes manual or third-party data input.
- Native mobile apps (Android/iOS)—web app only (PWA-capable).
- In-app payments or wallet integration—reservations are free or “pay at lot”.
- Dynamic pricing algorithms (e.g., surge pricing).
- Integration with city traffic control systems.
- Enforcement or violation tracking (e.g., towing).

## **8. Feature Comparison with Real-World Systems**
| Feature | **Proposed Smart Parking Finder** | **Existing Systems (e.g., Google Maps, Parkopedia, JustPark)** |
|--------|----------------------------------|--------------------------------------------------------------|
| **Real-Time Availability** | ✅ Manual + sensor-ready (Sri Lankan context) | ❌ Google Maps: mostly static info<br>✅ Parkopedia: limited to partnered garages |
| **Reservation** | ✅ For any registered lot (even small private ones) | ❌ Google: no booking<br>✅ JustPark: only commercial lots |
| **Low-Cost for Small Lots** | ✅ Free registration; no hardware needed | ❌ Most require IoT sensors or monthly fees |
| **Local Relevance** | ✅ Built for Colombo, Kandy, campuses | ❌ Global apps lack Sri Lankan parking data |
| **Offline Use** | ✅ Caches recent searches | ❌ Requires constant internet |
| **No Payment Complexity** | ✅ Pay at lot — no in-app wallet | ❌ Many apps force digital payments |
| **University/Campus Focus** | ✅ Can deploy at UoM, SLIIT, etc. | ❌ Not tailored for academic zones |
> ✅ **Key Innovation**: This system **democratizes smart parking**—enabling even a small private garage owner in Maradana to appear alongside major malls, using only a smartphone.
