Northeastern students develop ‘smart bike’ tech to curb cycling deaths (Video)
Boston Business Journal - 01/21/2014
A group of mechanical engineering students at Northeastern University are working on new technology for bicycles that aims to decrease fatalities among cyclists in urban cities.
The project is called the Interactive Bicyclist Accident Prevention System — and informally known as the “smart bike.” The technology uses sensors that detect the distance of a bicycle to cars on the street.
“Based on that, we collect the relative velocity of the two and we can predict whether an accident is going to happen,” said Amir Farjadian, a Ph.D. candidate studying bio-engineering.
If the sensors detect a potential accident, the bike will alert the cyclist about the danger through a built-in speaker.
Laser lights are also added to the bicycle to project a bike lane onto the street, so that the cyclist knows where the bike’s safe zone is. If a vehicle gets too close to the zone, the lasers — which can be seen during the day — will blink. Vibration technology on the bike will also cause the handlebars to vibrate if cyclists speed up as they approach an intersection.
