Open Cycling Data [#RARITAN]

Group members

Idea and Motivation

The idea is to crowd source bicycling data in terms of the cycling routes and times to improve biking conditions in cities.

With the help of this data, the city, municipality or region could maintain and provide biking routes that correspond to the demand and enhance services on busy routes. Also analysis in terms of traffic (e.g. traffic lights) could consider the cycling data.

The user just needs to run a mobile application while he is biking to track the route. The tracked routes will then be sent to the server. The anonymously gathered data will be accessible via an open REST API.

Concept

Features

Mobile Application

The mobile application will provide this set of features:

Feature Details Goal Implemented
Record Cycling Route Tracking the GPS coordinates of the mobile phone and saving them on the phone Must-have YES
Upload Tracked Data Sending the trip information to the server Must-have YES
Provide Cycling Information Providing information to the user about the tracked routes As time allows YES, but only basic tracked data
Integrate external data Sending the trip information to the server Optional Dummies

Webserver

The webserver allows to store and retrieve data through the REST API which provides:

Feature Details Goal Implemented
Query data Querying the gathered data in terms of date and location with different granularities to make it accessible for the public. Must-have YES
Add data Adding new routes with GPS and time information sent by the mobile application Must-have YES
Add meta data to GPS route data For good searches the GPS data has to be enhanced with meta information like time, country or city. Must-have YES
Different Respond Formats Providing different formats like GEOJSON or just coordinates as respond Optional YES

External Webservice

To demonstrate what could be done with the data we implemented an example service which accesses the Open Bicycling Data:

Feature Details Goal Implemented
Bicycling Density Route Usage Map A map that visualises the Open Bike Data to show busy routes. Optional YES
Focus map and filter data Focus map by URL params and only request the data of the specified country/region Optional YES

Platforms and Technologies

RESTful Open Cycling Data API

Documentation

The complete Open Cycling Data API Documentation is available in .json and .yaml format: open_cycling_data_api.zip

A short summary: The API can be accessed via https://lutcodecamp-niklaskolbe.c9.io/biketracks/{datarequest}/{country}/{region}?{parameters}

It allows following optional parameters:

"External" Webservice

The “external” webservice is accessible via http://lutcodecamp-niklaskolbe.c9.io/{country}/{region}

The web service accesses the Open Cycling Data API and creates a google heat map.

By specifying a country and/or a region the map will be centered and the data filtered accordingly. As for the API, the website accepts the optional parameters year, month and day and also filters the data accordingly.
