COPS USE NEW DETECTOR LIKE RADAR FOR BIKE-BUZZERS

“Did you know there’s a law in many states dictating how much passing space you need to give a bicyclist on the road? Wisconsin set the tone for the legislation back in 1973, and since then 33 states have added some kind of legislation of the books covering “Safe Passing,” 26 of which have set an actual minimum distance between the driver and the bike.

Up until now that has been a mere suggestion, since there’s been no real way to measure such offenses other than by eye. Codaxus LLC, an Austin-based startup has created an ultrasonic detector called Physics Package C3FT that mounts to bicycle handlebars expressly for the purpose of deducing passing distances. The detector itself sits on an adjustable arm and displays the distance measurement; sound and LEDs let the rider know when they’re too close.

Police use ultrasonic device to make sure drivers stay 3 feet from cyclists

Chattanooga Police now armed with custom-built device to teach drivers the law.

“For the last month now, Chattanooga Police Officer Rob Simmons has been biking around town with a new, unique ultrasonic sensor to make sure that drivers are obeying the state’s three-foot buffer law.

The law, which took effect in 2007, requires that when motorists pass a bike, they’re supposed to allow that much distance. But enforcing this law using only human eyes is pretty much pointless—it would be like trying to enforce speed laws without a radar gun. Tennessee is one of 24 states nationwide to enact such a law, but no other states have enforced the law using a device like this.

SENSOR RIG FINDS OUT IF MOTORISTS ARE SHARING THE ROAD WITH CYCLISTS

“Apparently there’s some cause for concern when it comes to bikes and automobiles sharing the roads in Austin, Texas. [Christopher Stanton] wrote in to tell us there’s a law on the books now that requires motorists to give three feet of space when passing a cyclist. This is pretty difficult to enforce as there’s no solid proof like the radar gun provides when it comes to speed limits. The hardware above is seeking to help by collecting data on passing habits. It measures and records the distance of each vehicle that passes you while on the bike. The goal isn’t to ticket more drivers, it’s to collect statistical data that might help change dangerous driving habits.
