Good Vibrations

Use iPhone telemetry to classify your rides, road conditions, and road types.

Project overview: https://youtu.be/vsSyaQ-A7XM

Here is a ride in Mercer Meadows near Princeton:

Pet Project Roadmap

• Persist telemetry from past rides to crowd-source road conditions across many rides and potentially across many riders
• Accept streaming input of SensorLog telemetry to avoid cli-geekery to achieve all this
• Interactive application where you input starting and ending location, ride type desired (or tolerable) and a dynamic route is generated based on ground conditions
• Warning notifications for bumps on the road based on actual rider location
