Cychic: safer biking through smarter sensing

Safe-Cyclist Project (Night-Rider)

Anthony RoweAssistant Research ProfessorElectrical and Computer Engineering Department Carnegie Mellon University

Is cycling safe?

• Yes and No• 677 Killed in 2011 (32,367 by car)

– 2.17 per million riders (1.10 by car)– 72% Urban– 33% at Intersections– 53% during evening commute (4pm-12am)– Average age for deaths 43

• Est. 48,000 Injured in 2011– Average age for injury 32– Many not reported

Lots of activity in this space…

RTKLib + Radio PMUs

Reactive Lighting

• Connected Head / Tail light• Change color / brightness / tempo

– Acceleration– Proximity– Environmental Conditions

Connected Helmet

• IMU tracks head motion– Is the rider paying attention?– Have they looked back recently?

• Binaural alerts from speakers
