[Back to Hacking 2021] Providing alternative carbon efficient travel paths within a specified time limit. Entry by SAP Hana and Analytics FPA61 Interns

Back To Hacking 2021: Go Green

Project Motivation

Environmental problems are always a hot topic. We want to let everyone help the environment by reducing the amount of carbon footprints in their daily travel, so we come up with the idea to create a Google app with carbon footprints.

App functions

The app provides users alternative routes along with carbon footprints under a user defined time constraint, so they can leave the least amount of carbon footprints as well as arriving the destination efficiently.

Technology

We use React as frontend and Express as backend. In the frontend, the user can enter the origin, destination and time limit in the search bar, and a map is pre-loaded with Google map api. When a request is formed, it will return all the alternative routes in the order of least to largest carbon footprints. We created a formula with time and carbon footprint included to list the order.

Difficulties

we are not familiar with frontend and can't load the map well

Success

we sorted out a /maproutes api with all the data correctly returned.

Fontend:

cd /website and use npm start to start the map

Backend:

run app.js and query localhost:3000/maproutes using body params origin, destination and timelimit in order to retrieve our carbon score and other information pertaining to the route.
