VTrack: Real-time Vehicle Tracking and Booking System

Objectives

1. Develop a mobile app for real-time tracking and booking of rented cars.
2. Implement secure user authentication and data management.
3. Integrate real-time maps for vehicle tracking.
4. Ensure a seamless user experience across devices.

Introduction

VTrack enhances efficiency in the vehicle rental industry by offering real-time tracking, booking, and management through a user-friendly mobile app. It uses Firebase for authentication, MongoDB for data management, and Google Maps API for real-time tracking.

System Model

• Frontend: React Native for cross-platform consistency.
• Backend: Firebase for authentication and real-time DB management; MongoDB for complex data storage.
• Maps Integration: Google Maps API for real-time tracking.
• OTP Verification: Secure OTP-based user verification using Firebase Authentication.

Flowchart

1. User Registration/Login:

   • Enter phone number
   • OTP sent and verified
   • User details stored

2. Vehicle Booking:

   • Select a vehicle
   • Confirm booking details
   • Store booking details

3. Real-time Tracking:

   • Track vehicle in real-time using Google Maps

Implementation Details

OTP Function

import auth from '@react-native-firebase/auth';
import firestore from '@react-native-firebase/firestore';

const sendOTP = async (phoneNumber, countryCode) => {
  try {
    const fullPhoneNumber = `+${countryCode}${phoneNumber}`;
    const response = await auth().signInWithPhoneNumber(fullPhoneNumber);
    setConfirmData(response);
    Alert.alert('OTP Sent', `OTP has been sent to +${countryCode} ${phoneNumber}`);

    // Save phone number to Firestore
    const docRef = await firestore().collection('phoneNumbers').add({
      number: phoneNumber,
      timestamp: firestore.FieldValue.serverTimestamp(),
    });

    return { success: true, docId: docRef.id, confirmData: response };
  } catch (error) {
    console.error(error);
    return { success: false, error: error.message };
  }
};

Maps Fetching Code

import MapView, { Marker } from 'react-native-maps';
import React from 'react';
import { View, StyleSheet } from 'react-native';

const MapScreen = ({ route }) => {
  const { latitude, longitude } = route.params;

  return (
    <View style={styles.container}>
      <MapView
        style={styles.map}
        initialRegion={{
          latitude: latitude,
          longitude: longitude,
          latitudeDelta: 0.0922,
          longitudeDelta: 0.0421,
        }}
      >
        <Marker
          coordinate={{ latitude: latitude, longitude: longitude }}
          title={"Vehicle Location"}
        />
      </MapView>
    </View>
  );
};

export default MapScreen;

DB Connection (MongoDB)

const mongoose = require('mongoose');

const connectDB = async () => {
  try {
    await mongoose.connect('mongodb://your_mongo_db_uri', {
      useNewUrlParser: true,
      useUnifiedTopology: true,
    });
    console.log('MongoDB connected...');
  } catch (err) {
    console.error(err.message);
    process.exit(1);
  }
};

connectDB();
