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…

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
