We wanted to explore uses for machine learning, so we decided to create a tool to predict availability of Capital Bikeshare stations depending on location, time of day, and weather.
We used the large amount of trip data DC's Capital Bikeshare has made available to the public, combined with other historical data, and applied statistical methods. To increase accuracy, we added weather data to the learning system.
We quickly built a web page and a REST API that collects user input and displays predictions for the given location, date, and time. Next, we decided to add a conversational interface so we can access the API using natural language. We also added a Slack bot integration so that users can access the solution right in the chat window.
We created a prototype AR app for the iPhone that shows users where the nearest Capital Bikeshare station is relative to the user’s location and directional orientation. The AR overlay shows the name and distance of each station.
We created both a haptic compass that buzzes according to the direction of an iPhone and a standalone haptic device to detect iBeacons without the use of a smartphone.
