Google Transport Tracker

========================



Google Transport Tracker is a set of applications designed to track a

range of moving assets (such as vehicles) and visualize them on a live map. The

applications use a mixture of technologies - Android, Firebase,

Google Maps, GTFS (General Transit Feed Specification), and more.



**Note:** This application implements asset tracking. For use in a production environment, you therefore need a [Google Maps APIs Premium Plan license](

https://developers.google.com/maps/pricing-and-plans/). For more information, see the [Google Maps APIs terms of service](https://developers.google.com/maps/terms#section_10_4).



## Overview



This is the open source release for the 

[I/O Bus Tracker](https://io-bus-tracker.appspot.com/).



The repository consists of a number of components, representing the individual

moving parts of the bus tracking system. It includes an Android app,

in `/android`, that's installed on Android devices and deployed on the tracked

vehicles, along with a matching administration UI in `/admin`.



The repo also contains the display side of the system, designed to drive 60"

LCD TVs. There is `/backend`, written in Node.js and running on Google Compute

Engine, which receives the locations reported by the Android app, along with a

time table provided in GTFS format, and makes regular updates to a Firebase

Real Time Database. The client in `/map` receives the updates from the Firebase

database and draws them on the LCD TV.



## Getting started



See the [developer documentation](https://developers.google.com/maps/solutions/transport-tracker/start).



## Directories in this repo



The project contains the following subdirectories, each housing

a single component:



### `admin`



A web interface for administrators to see a quick overview of all the

assets being tracked.



### `android`



The Android app that resides with each asset to be tracked.

Once configured, this app keeps its location synced with Firebase, and reports

on other metrics, such as battery life.



### `backend`



The server-side component that manages the state of the Firebase database.  For

a tutorial on this component, please see 

[Transport Tracker Backend codelab](https://codelabs.developers.google.com/codelabs/transport-tracker-backend/)



### `map`



The public web interface that displays schedule information and asset

locations. For a tutorial on this component, please see 

[Transport Tracker Map codelab](https://codelabs.developers.google.com/codelabs/transport-tracker-map/)
