How to Build an App That Can Analyze Bike Traffic Patterns in NYC Using Redis

Citi Bike, New York's popular bike share program with over 20,000 bikes across Manhattan, Brooklyn, Queens, and the Bronx, has a new app that allows users to discover how many bikes are used at different times throughout each day in various neighborhoods. The app uses RedisGraph for lightning-fast queries, enabling users to visualize traffic patterns around the network. Users can drag a geospatial index across different locations to uncover precise figures on Citi Bike usage over time. This application is built using React and around react-mapbox-gl, with an aggregated trip graph constructed using devexpress/dx-react-chart. The offline importer downloads public Citi Bike trip data, unzips each archive, and indexes all of the trips into a journeys graph.
