Engineers at the University of Minnesota (U of M) have designed a prototype smart bicycle which they say can protect itself from collisions.
A Light Detection and Ranging (LiDAR) sensor at the front of the e-bike scans for cars at approaching intersections, while rear and left-side lasers track vehicles behind and adjacent to the bike.
U of M's Rajesh Rajamani said an onboard microprocessor reads this data and algorithmically forecasts a vehicle's trajectory by calculating its relative velocity to the bike.
The system sounds a horn to warn the driver of the vehicle if a collision is imminent.
Rajamani said the system is able to predict the most common types of bike-vehicle collisions from as far away as 30 meters (98 feet).
