The handlebar sonar unit that measures passing distance

Device has been developed to help with the enforcement of passing laws

BikeBiz reports on a bike-mounted system that can calculate the proximity of passing vehicles. The C3FT device has been developed for the enforcement of safe passing laws by Austin-based engineering firm, Codaxus.

The C3FT uses an ultrasonic detector on an adjustable arm with the measurements immediately displayed on a numeric display. The device can also be set up to buzz when a vehicle passes inside a preset threshold.

The Chattanooga Police Department currently makes use of the system to enforce a 3ft passing law, reasoning that judging distance by eye or from video footage is difficult. Codaxus suggests that it could also be used by researchers and local authorities and there is also scope for it to be used by the public in combination with a helmet cam should a person need to prove that a car passed them dangerously closely.

Handlebar-mounted sonar checks for close overtakes

“Measuring the distance a motorist gives a cyclist when overtaking is usually done by “eye” or by estimating distance from video recordings, both of which can suffer from inaccuracies. Now an American company has created a handlebar sonar unit.

The C3FT was designed by Austin-based engineering firm Codaxus for a US police force in a State with a “3 foot passing law”. However, the unit could be used by academics, local authorities and police forces worldwide. Video-equipped cyclists now regularly post footage of close overtakes but the cameras favoured by “helmetcam” cyclists often give distorted wide-angle views.

Bike Sonar Is Helping Police Catch Drivers Who Squeeze Cyclists

The three-foot rule used to be impossible to enforce. But now your bike can enforce it for you.

“Florida handed out around 500 tickets last year to drivers who veered too close to cyclists when passing. But only eight drivers were actually found guilty.

Like 26 other states, Florida has a law requiring cars to give bikes at least a three-foot gap of space.

The problem is that it’s fairly impossible for a cop to judge exactly how far away a driver is and issue a ticket (or win a case if they do). So a new gadget uses sonar to measure.

Bike Sonar C3FT Is Helping Cops Catch Rude Drivers That Ride Too Close To Cyclists

“If you are a frequent cyclist, chances are you have had a close encounter with a car that was riding a little bit too close to the bike lane. But now a new bike sonar has been developed that is helping cops catch these rude and unsafe drivers.

According to the National Conference of State Legislatures (NCSL), as of June 24, there are 25 states that have safe-passing laws to make sure that vehicles share the road with cyclists, giving them 3 feet of space to prevent sideswiping accidents.

Florida, one of the states that enforces the 3-foot law, gave out about 500 tickets last year to drivers who failed to share the road. While these laws are enforced, it’s close to impossible for police to know the exact distance between cars and bikes to hand out a ticket or win the case once the ticket is written.

With the device attached to a handlebar, a bike cop gets a ping if a driver gets inside the three-foot zone. One of the inventors compares it to a radar gun that an officer would use to see if someone’s speeding. “I think it’s a fine enough line that you really do need some technological proof,” says Christopher Stanton, co-founder of Codaxus, the Austin-based engineering firm that created C3FT (the name spells out “see three feet”).

Chattanooga, Tenn., Tests Technology That Could Make Roads Safer for Cyclists

Most states have laws to protect bikers from cars, but they’re hard to enforce. One city is testing a new device that makes it easier.

“Last month, Alabama Gov. Robert Bentley signed a bill into law requiring drivers to pass bicyclists at a distance of at least three feet. That makes Alabama the 35th state with a “safe passing” law that specifically mentions bicyclists. As police in Alabama look to implement the new law, they may want to learn from a pilot project underway in Chattanooga, Tenn., where cops use radar and cameras to hold drivers accountable for violations.

Safe passing laws have seen dramatic growth in popularity over the past 20 years. In 1973, Wisconsin became the first state with such a law aimed at protecting bikers. All states have a safe passing law of some kind, but until the early 2000s, only three followed Wisconsin’s example of prescribing a specific distance for passing a bicyclist. Now, more than half do.

Next City (July 10th, 2015)

This Invention Could Boost Bicyclist Protection Laws

“It took just a quarter of a mile with the device mounted on the handlebars of the patrol cop’s bicycle before it became obvious: This invention by a little Austin company, designed to enforce laws requiring that vehicles give at least three feet to cyclists when passing, could actually change the roads for cyclists everywhere.

“I was riding in full uniform and within three blocks, I had a car pass me inside three feet,” says Chattanooga police Officer Rob Simmons. “And it was all day long.”

A bike cop in the southern Tennessee city for seven years, Simmons didn’t realize just how often drivers broke the law when passing him — and figures the drivers didn’t either.

American City & Country (July 1st, 2015)

C3FT adds teeth to passing law in Chattanooga

“For Chattanooga Police Department Officer Rob Simmons, patrolling motorists passing habits on the road became personal a few years ago.

The bike patrol officer’s friend, David Meek, died in a cycling accident in 2009 after a motorist failed to follow Tennessee’s “three-feet” passing law, which requires motorists to remain three feet from cyclists when passing.

“He got sideswiped by a vehicle trying to pass him,” Simmons told American City & County. “That really resonated with me.”

Simmons has led the effort for his police department to be the first in the country to utilize C3FT V2.0 – a bicycle-mounted passing detector system – that will better educate and enforce vulnerable road user laws, which apply to pedestrians, cyclists and others.

A Nifty Device to Stop Cars From Driving Too Close to Bikes

“Maybe your state is one of the more than two dozen around the U.S. with what is known as a three-foot passing law—a provision that requires drivers to give people on bikes at least that much clearance when passing them on the road. (Pennsylvania calls for a more generous four feet.) But are these laws enforceable? Or are they just an empty promise of safety?

One police officer in Chattanooga, Tennessee, wanted to find a way to give the law in his jurisdiction some meaning. Officer Robert Simmons, who has been with the city’s department for 12 years and on full-time bike patrol for seven, came up with an idea for a device that can measure and record the distance between a bike and a car.

“I thought, I wish there was a data-driven way, like a radar gun,” says Simmons. “This is what I want to build; this is what we need to prove it in court.”

Cycling Cop Creates Space for Cyclists on Tennessee Roads

New technology and one dedicated bike cop are changing the face of cycling law

“Rob Simmons is one of those cops who loves cyclists. He has been a recreational rider for years and is currently a bike patrol cop in Chattanooga, Tennessee, where police officers have been using groundbreaking new technology to explain cyclists’ rights to oblivious drivers.

More than 20 states have a law requiring drivers to allow at least three feet of clearance when passing cyclists, yet those laws are rarely enforced. However, in Chattanooga, Simmons spends chunks of his day chasing down lawbreakers on his bike, showing them just how close they came to him on his bar-mounted GoPro camera and explaining the law.

RELATED: The Secret to Safer Streets

Thanks to a device called the C3FT, developed by Codaxus, LLC, Simmons knows to the inch exactly how close drivers come to him. All of the drivers who he pulls over are given educational pamphlets, and those who haven’t learned their lesson get tickets and can be sent to a 90-minute “Cycling 101” class with Outdoor Chattanooga for re-education.
