Traffic Tracker

Traffic Tracker efficiently allows you to factor commute time into your decision-making process by keeping track of the commute time for long-time period.

Traffic Tracker gathers real-time traffic data for the added route. It uses Google API to get the most recent changes in the traffic and commute time. By tracking traffic over long period of time (e.g. 3 months), you can see traffic patterns on the added route. Data analysis helps you to decrease the time spent in the traffic and find the convenient commute window.

Setup

To use this application, you'll need to take the following steps:

• Create a new, empty directory on your machine and git init (or create an empty repo on Github and clone it to your local machine)
• Run the following commands:

git remote add traffictracker https://github.com/kwegorek/traffictracker.git
git fetch traffictracker
git merge traffictracker/master

Why did we do that? Because every once in a while, traffictracker may be updated with additional features or bug fixes, and you can easily get those changes from now on by entering:

git fetch traffictracker
git merge traffictracker/master

Customize

Now that you've got the code, follow these steps to get acclimated:

• npm install
• Create two postgres databases (traffictracker should match the name parameter in package.json):

createdb traffictracker
createdb traffictracker-test

• By default, running npm test will use traffictracker-test, while regular development uses traffictracker
• Create a file called .env in the project root
  • This file is listed in .gitignore and put there your own API KEYS

GOOGLE_CLIENT_ID = 'hush hush'
GOOGLE_CLIENT_SECRET = 'pretty secret'
GOOGLE_CALLBACK = '/auth/google/callback'
GOOGLE_DISTANCE_API_KEY = 'YOUR_API_KEY'

Google Place ID Geocoder && Distance Matrix API

Google place id geocoder: https://developers.google.com/maps/documentation/javascript/examples/places-placeid-geocoder

The Distance Matrix API is a service that provides travel distance and time for a matrix of origins and destinations. The API returns information based on the recommended route between start and end points, as calculated by the Google Maps API, and consists of rows containing duration and distance values for each pair.

API response:

https://maps.googleapis.com/maps/api/distancematrix/json?origins=place_id:EiFIb3l0IEF2ZSBTLCBRdWVlbnMsIE5ZIDExMTAyLCBVU0EiLiosChQKEgkFFzxHRF_CiRGVwYvSrucNdhIUChIJU6W15zZfwokRDhGErMSvCpw&destinations=place_id:ChIJU6W15zZfwokRDhGErMSvCpw&departure_time=now&key=API_KEY

{ "destination_addresses": [ "Astoria, Queens, NY, USA" ], "origin_addresses": [ "Hoyt Ave S, Queens, NY 11102, USA" ], "rows": [ { "elements": [ { "distance": { "text": "1.1 km", "value": 1114 }, "duration": { "text": "5 mins", "value": 325 }, "duration_in_traffic": { "text": "6 mins", "value": 376 }, "status": "OK" } ] } ], "status": "OK" }

OAuth

• To use OAuth with Google, complete the steps above with a real client ID and client secret supplied from Google
  • You can get them from the Google APIs dashboard.

Start

Running npm run start-dev will make great things happen!

If you want to run the server and/or webpack separately, you can also npm run start-server and npm run build-client.
