Drivers who drive a little too close to cyclists on the road could soon be caught on the spot. A new technology adopted by legal departments in Ottawa could help carryout legal distance between bikers and cars on the road.
The device, which is fixed on a bicycle’s handlebars like a bike bell, uses sonar (声呐) technology to measure the distance between the bike and passing cars. The device will make aloud noise if the car is within one meter of the bike, the legal limit in the city of Ottawa, allowing the police rider to radio ahead to his colleagues so that the driver can be pulled over. “The safety of all road users is extremely vital, including cyclists. These cycling changes are directed at encouraging cycling. promoting road safety, and sharing the road,” said Rob Wilkinson, coordinator of the Safer Roads Ottawa Program.
The authorities started the program last week with a single sonar device. One police officer rode the bike bearing the device around the city on Tuesday to prove the effectiveness of the technology. Within a few minutes of riding, the device was beeping, registering that two drivers had violated the one-meter distance requirement. The drivers were pulled over and given brochures informing them that they had broken the safe distance law.
Wilkinson noted that the device is not currently being used to issue fines, which can go up to $110, and that there are no plans to use it for enforcement (执法) in the future. At this point its main use is to spread awareness about the safe distance law, which was passed last September in an effort to encourage rider safety and reduce deadly crashes.
