New tech catches drivers not sharing the road

“How close is too close when passing a cyclist?

Ottawa police officers are using new technology to crack-down on drivers who aren’t sharing the road.

As of January, a new Ontario law means drivers cannot come within one-metre of a cyclist when passing. If you get too close, you could get slapped with a 110-dollar fine and three-demerit points.

Right now this is really an education campaign, a chance for police to warn drivers of the new rules. Police say it’s obvious something needs to be done because 1-2 cyclists are struck by vehicles every day in Ottawa’s downtown core.

Executive Style (June 9th, 2016)

The device that measures cyclist passing distances

“It’s a device that measures one of the most contentious distances in Australian road safety – the amount of space between a bicycle and an overtaking car.

Called the C3FT, it has an ultrasonic sensor mounted on the bicycle’s handlebars to calculate how near the vehicle came to the bike.

Use of the device was pioneered a year ago by police in Chattanooga, Tennessee, a city that has a three-foot buffer law when drivers overtake cyclists – similar to the metre and 1.5-metre passing measures now found in half of Australia’s states and territories.

Topeka Police Department on the road to enforcing ‘3-foot rule’ regarding bicycles

Officers plan to start by mounting education campaign

“Topeka police are gearing up to mount a public education campaign about the “3-foot rule,” which bans motorists from driving within 3 feet of a bicyclist.

The campaign will be accompanied by a grace period in which violators will be warned instead of cited, Police Chief James Brown told more than 50 cyclists who took part in a six-mile “Ride With the Chief” early Tuesday afternoon.

Vulnerable User Laws & C3FT device

“Christopher Stanton, one of the inventors of the C3FT ultrasound device, discusses how it can be used to enforce the vulnerable users law and – more importantly – raise awareness of the laws intended to protect cyclists and other non-motorists on our roadways.

1,5 m: El radar que caza al infractor

“El sistema de radar móvil encargado de cazar a estos infractores se denomina Codaxus C3FT y se compone de un sensor ultrasónico capaz de medir la distancia y una cámara para registrar las infracciones. Por el momento es el dispositivo que usa la Unidad Ciclista de la Policía de Chattanooga (Tennessee, EE.UU.), que una vez montado en sus bicicletas detecta a todo aquel conductor que los rebase e incumpla la normativa.

En España ya se han intentado llevar a cabo medidas de este tipo, en buena parte impulsadas por colectivos ciclistas. De hecho, el 30 de octubre de 2014, la Dirección General de Tráfico llegó a estudiar la posibilidad de crear una nueva unidad de la Guardia Civil. A propuesta de la Asociación de Ciclistas Profesionales, se propuso la creación de  un nuevo cuerpo policial camuflado de ciclista que usara un sensor muy parecido al que actúa en Estados Unidos. La realidad es que desde entonces no se ha vuelto a tener noticias de ello.

“The mobile radar system in charge of hunting these offenders is called Codaxus C3FT and consists of an ultrasonic sensor capable of measuring the distance  and a camera to record the infractions. At the moment it is the device that uses the Police Cyclist Unit of Chattanooga (Tennessee, USA ), that once mounted on its bikes it detects to all that driver that passes and it breaches the regulation.

In Spain already have tried to carry out measures of this type , to a large extent driven by collective cyclists. In fact, on October 30, 2014, the  General Directorate of Traffic came to study the possibility of creating a new unit of the Civil Guard. At the proposal of the Association of Professional Cyclists , it was proposed the creation of   a new police body camouflaged cyclist who used a sensor very similar to the one that operates in the United States. The reality is that since then there has been no news of it.


Todo Mountain Bike (October 15th, 2015)


‘No respetar el metro y medio de seguridad a la hora de adelantar a los ciclistas en la carretera es uno de los comportamientos más comunes que la mayoría de usuarios de bicicletas suelen presenciar en sus salidas rodadoras. A pesar de que se trata de una grave y peligrosa infracción que puede costar la vida a un ciclista, muchos conductores imprudentes siguen sin respetar esta norma, ya sea por ¿desconocimiento? de la misma o porque, tristemente, a día de hoy resulta muy difícil ‘cazar’ a un conductor realizando un adelantamiento peligroso.

A principios de 2014, el subdirector de normativa de la DGT, Manuel Villalba, se mostró partidario de crear una nueva unidad de tráfico en la que agentes de la Guardia Civil, camuflados de ciclistas, velasen por la seguridad de los usuarios más indefensos de la vía. Esta interesante medida fue propuesta por la ACP (Asociación de Ciclistas Profesionales) a raíz de un estudio sobre adelantamientos a ciclistas realizado por el Centro de Estudios Ponle Freno-AXA de Seguridad Vial; un estudio ‘de campo’ realizado con dispositivos de medición específicos que demostró de forma tajante que uno de cada cinco conductores no respeta la distancia de seguridad en los adelantamientos a ciclistas.

Auto-translation of first two paragraphs:

Not respecting the one and a half meters of safety when it comes to overtaking cyclists on the road is one of the most common behaviors that most bicycle users often witness at their wheeling exits. Although it is a serious and dangerous violation that can cost a cyclist life, many reckless drivers still do not respect this rule, either because of ignorance? Of the same or because, sadly, today it is very difficult to ‘hunt’ a driver making a dangerous overtaking.

At the beginning of 2014, DGT’s deputy director of regulations, Manuel Villalba , was in favor of creating a new traffic unit in which Civil Guard agents, camouflaged by cyclists, sailed for the safety of the most defenseless users of the via. This interesting measure was proposed by the ACP (Association of Professional Cyclists) following a study on overtaking to cyclists conducted by the Center for Studies Ponle Brake-AXA Road Safety ; A field study conducted with specific measuring devices that clearly showed that one in five drivers does not respect the safety distance in the overtaking to cyclists.

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.

International Police Mountain Bike Association (July 30th, 2015)

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.
