How Can a Smart City Make Life Easier for People with Disabilities?

 

In recent years, digital technology has contributed to undeniable advances that have made life easier for everyone. At a time when this technology is at the heart of building new smart cities, what can be done to ensure that the situation of disabled people is alleviated and not aggravated? How can everyone’s specific needs be taken into consideration? In essence, how can a smart city be made inclusive?

We offer a reflection on this hugely strategic topic for the future!

What Is a Smart City?

A smart city is one that fully uses information and communications technology (ICT) to create an environment that can sustainably develop. This concept originates from the idea that digital technology can be used to improve the life of human beings. On a practical side, a smart city is basically based on a sensor network, connected objects and data management systems, which constantly collect and transmit information on the weather, air pollution, traffic flows, energy use and other factors. This data is then analyzed in real time, allowing local governments, businesses and even citizens to make informed decisions.

Many of the world’s cities and metropolises have taken steps in transitioning to becoming smarter, connected cities. Their approach is centered on areas such as air quality, traffic circulation, energy savings, full use of public spaces, ease of travel and active transport.

The creation of a smart city is simply a new way of conceiving the city. The use of digital technology is incorporated into the physical infrastructure so that residents and users receive the best service.

Disability as an Innovation Driver for the Smart City

New York City is even testing a more connected accessible pedestrian signal with aBeacon. Blind and visually impaired pedestrians can activate it with a remote control or a smartphone. They don’t have to press the pushbutton. This on demand and remote activation enables them to better locate the beginning of the crossing.

Plus, aBeacon can collect information regarding the number of users with visual impairments who have been activating it. This can be quite useful for all smart cities.

The first user testimonies are quite positive which makes this augmented accessible pedestrian signal a true innovation.

Singapore: the most intelligent city

Singapore is considered to be the most intelligent city and thus, the most accomplished example of a smart city in the world. Why? Thanks to the digitalization of the public services of the city-state, Singapore provides its citizens with a superior quality of life. Its goal? Smoothen everything to make their everyday lives easier.

But it goes beyond that by making its citizens actively participate in the creation and the improvement of the city’s services. For example, Singapore gave them access to an online design tool to conceive what one of the airport areas will look like. But the city-state also used data analysis from the social media of its citizens to map its cultural activities.

Singapore has perfectly understood what a smart city should be: to meet the needs of its citizens and to fully suit them, the city needs to be moulded according to their image. Consequently, even if technology is at the centre of the smart city, it remains managed, modified and controlled by humans.

How Could Disabled People Benefit from the Advances of a Smart City?

The cities involved in this transition generally perceive a smart city as a path towards a more environmentally friendly and human place to live. Looking at the number of projects by students, engineers and start-ups proposing technological solutions for disabled people, there is an obvious drive towards the construction of an inclusive smart city. Yet, real-life examples of such a noble idea remain few and far between. The solutions put forward are either based on a promising technology that still neglects the real needs and uses of those to whom it is directed, or are based on actual needs and uses but the solution’s sustainability is jeopardized because it lacks a viable economic model.

The way to enable disabled people to benefit from the advances of a smart city is to consider their specific needs from the very start of the projects. Just like physical accessibility for roadways and buildings, the cost for digital accessibility is almost minuscule when integrated into the design brief at the very beginning. Project stakeholders just need to be aware of this!

Let’s use the example of Singapore one more time: its public space is one of the most accessible places in the world. The same holds true for its public transport, its cultural venues such as museums and even for its sporting facilities that are adapted to parasports. Accessibility isn’t taken slightly by the city-state and neither is inclusion!

Singapore created “Enabling village”: a concept of experimentation focused on disability, accessibility and inclusion for people with disabilities. Based on universal design, this inclusive village strives to train and employ people with disabilities.

Overcoming Barriers to an Inclusive Smart City

According to a 2016 survey by Smart Cities for All, experts from around the world identified the lack of awareness about disability and accessibility in design and innovation as one of the main impediments to the “Smart City for All.”

On the other hand, the time users need to learn new technologies also represents a barrier. Elderly people, who often have a disability, are those who have the greatest trouble in adapting to new tools. Moreover, the free flow of data sometimes generates irrational fears. Therefore, education on these different solutions is an important matter.

As for the perspective of decision-makers, making way for innovation is not always possible. Large swathes of urban land are governed by specific rules and regulations. Meanwhile, the appropriation of public funds to experiment with new technology is generally seen as too risky. Such a decision can only arise from strong political will.

Finally, building an accessible or inclusive city needs to respect the continuity in the travel chain. For an inclusive smart city, we must also guarantee continuity in the information chain. The management of urban spaces is shared among many and varied public and private entities: municipalities, inter-municipalities, county, region, transportation operators, business, individuals, etc. A person in a wheelchair can’t enter an accessible building if the sidewalk doesn’t slope to the entrance: movement is impossible if the chain of information is broken.

The new services for the inhabitants and users of tomorrow will all be created from the same raw material: data. Far from being an exhaustible supply, as in the case of fossil fuels, the amount of data increases exponentially at 40% per year. The issue today is to make the data homogeneous, public and open, thereby allowing the creation of new services. Otherwise, such a colossal reserve cannot be tapped. Another issue directly linked to data relates to its life cycle. Data has to be made available in real time, and the data that becomes obsolete must be removed as soon as possible so the message doesn’t get distorted. Several technical committees focused on smart cities have already established different national and international standardization bodies.

Keeping the Human Being at the Heart of the Initiative

If data represents the fuel and the smart city the vehicle, the destination is nothing more than facilitating the lives of people in all their diversity. To reach the goal of an inclusive smart city, it is essential to analyze the specific needs and uses of the inhabitants. Information should be provided in a way that is adapted to each person’s physical abilities and limitations. The selection of information must also correspond to these criteria and take into account the person’s situation.

When we think “smart,” we think “digital.” Yet, our towns and cities are real, impregnated with their own history, geography and ways of life. Connecting the digital world to the physical world, a concept known as “phygital,” is a key element in building smart cities that are truly inclusive. As it is today, the communication of information relating to the physical accessibility of places is cruelly lacking. Accessibility to information should go hand in hand with accessibility to places so that everyone has proper access to services. The decision-makers of cities should look at questions of physical accessibility simultaneously with digital accessibility.

The above shows that a smart city can be a marvelous opportunity to make society more inclusive. However, services need to be developed not just for the masses but also with due regard for the specific needs of minorities. Political will, financial resources, a desire for technological innovation and, most of all, experiments and feedback on usage are the essential ingredients for an inclusive smart city.

How Do the Blind Safely Cross the Road?

How Do the Blind Safely Cross the Road?

How Do the Blind Safely Cross the Road?

 

Find a crosswalk, wait for the right moment, get to the opposite sidewalk by walking straight across. It is quite common for the average pedestrian. But for a person who has lost their sight, every step is complicated. This is especially true in today’s urban environments where more and more types of transportation methods coexist. Blind and visually impaired people can do nothing but trust their other working senses such as hearing and touch. Yet, they still need to rely on some clear indicators. This is where adherence to road and public space accessibility regulations makes sense.

Visual and Tactile Clues for Locating a Crosswalk

For people with impaired eyesight who can still make out differences in brightness, the white lines marking crosswalks are an essential aspect. They are also an excellent marker for guide-dogs, which are given the order “find the lines.” It is thus a reliable clue that must be used as much as possible.
Blind people who use a cane to get around, on the other hand, have further difficulties. They first find the general location of crosswalks based on the noise of traffic. Then, they search for tactile paving on the ground. The paving should have an obvious contrast in feeling from the rest of the sidewalk. Its visual contrast is also an aid for the visually impaired because its color generally lasts longer than the paint on the rest of the pavement.

Listening for the Right Moment and Staying the Course

Knowing the moment when the street is free to cross safely is perhaps one of the most distressing tasks for a person who is blind or visually impaired. Hearing is the main sense relied on at this stage.

However, keeping an ear out is not enough! Knowing how to analyze the traffic flow is a necessary skill. How many lanes are there to cross? What vehicles are using the street (cars, bikes, tram, etc.)? Are there traffic lights? Who has right of way? Street crossing skills are acquired through courses on Orientation and Mobility (O&M) for the blind. An O&M specialist is a professional who teaches those with poor eyesight how to orient themselves and walk in safety. It is also through these courses that a blind or visually impaired person knows how to maintain their direction during the crossing.

Limits to the Aids

The white stripes of crosswalks, the tactile paving, Orientation and Mobility training… none of that ever crossed your mind, did it? You are probably saying to yourself that it is great that all that exists, and you would be right! Unfortunately, it is not enough and many factors compromise these aids.

1. Crosswalks disappear due to time and the constant traffic. They are not always repainted to maintain the visual contrast. Furthermore, many pedestrian crossings are not marked out by white or yellow strips but by more subtle elements such as studs or cobblestones.

2. Tactile strips are not always placed in a way that serves as an effective point of reference. They are easy to notice when the sidewalk dips so that the change in gradient acts as an indicator. However, urban improvements placing the sidewalk at the same level as the road has become more common in an effort to help the movement of people with reduced mobility. This causes a loss of reference points for visually impaired people and makes it more difficult to find tactile paving. We should not forget either that under dead leaves or snow, the embossed paving can no longer be felt.

3. The number of vehicles using the street complicates the analysis of traffic by ear. In addition to the number, another complication is the almost silent nature of some vehicles such as bikes or electric cars that share the road with other extremely noisy vehicles like machinery and street cleaners. Furthermore, the absence of different levels or tactile points of references between different streets makes their identification impossible.

4. Finally, those with impaired vision who have had access to Orientation and Mobility training are very much a minority. O&M specialists are rare and not easily found outside large cities. Meanwhile, the quick changes to the urban environment require continuous refresher courses, which is far from possible today.

Accessible Pedestrian Signals (APS): a Vital Solution

Considering all this information, the use of a sound system on pedestrian signals or on other types of street furniture is essential nowadays. Of course, blind and visually impaired pedestrians need some training on the use of acoustic traffic signals. But such traffic signals solve a large number of difficulties, which is the reason why they have been mandated by accessibility regulations in many countries.

1. Acoustic traffic signals make it easier to find a crosswalk. When they can be activated from a distance by a remote or smartphone, such signals allow visually impaired people to easily locate a pedestrian crossing. They just need to follow the source of the sound.

2. These types of signals also indicate the best time to start crossing. Even though listening to the traffic remains indispensable in order to avoid accidents with a vehicle running a red light, lights with audio signals greatly facilitate decision-making. The beeps, tweets, bells or voice messages from the lights clearly indicate the moment to cross.

The customized message with the street name allows a person with impaired vision to distinguish the street they want to cross perpendicular to.

3. Acoustic signals allow a person to maintain a straight trajectory during the entire crossing.

The ultimate guide to accessible pedestrian signals. I want it!

Again, thanks to the sound, visually impaired people can orient themselves more easily during the crossing by listening to the sound emanating from the other side. Accordingly, it is essential that acoustic traffic signals are properly installed, as close as possible to the center of the crosswalk.

Even when pedestrian signals have been removed, for example, to improve traffic flow, it is possible to install audio beacons on buildings or integrate them into street furniture so that essential audible indications can still be provided to the visually impaired.

It should now be clear that crossing the road is an enormous challenge for the blind and visually impaired and not only because they have to deal with cars. Finding the edge of the street and crosswalks and staying on course during the crossing are all just as important tasks. All these issues must be taken into account when developing an accessible roadway.

7 Clichés About Psychiatric Disability

 

Psychiatric disability, or mental illness, has long been associated with insanity. It very often (and wrongly) prompts an irrational fear in us. Like all other disabilities, it has many forms and a person can lead an active life with appropriate support.

1. Psychiatric disability does not affect me

Unfortunately, no family is safe from mental health issues, whether depression, anxiety, addiction, schizophrenia, anorexia or other. The WHO estimates that these disorders affect one in four people and that mental illness now represents the most common disability in the world.

2. Intellectual disability and psychiatric disability are the same thing

Even though the results of these two types of disabilities sometimes resemble each other, it is important to distinguish between them.
Intellectual disability is the result of a cognitive impairment that affects a person’s ability to learn, think and conceptualize. Psychiatric disability is the result of disabling psychiatric disorders such as schizophrenia, major depression, bipolar disorder, anxiety disorders and personality disorders. It is also often called “mental illness” but this can increase confusion between the two disabilities. In any case, psychiatric disability does not affect a person’s intellect. It simply makes it more difficult for them to use their intellectual abilities in certain circumstances or in a particular emotional state.

8 Clichés About Intellectual Disability

3. People who live with a psychiatric disability are unable to work

One of the main difficulties facing people affected by a psychiatric disability is keeping their job. The unemployment rate among people recognized as disabled workers is twice that of the general population. Nevertheless, with personalized support (rearrangement of work schedule and environment), they are more than capable of working and contributing their skills. A job can even act as an effective way of preventing their disorder from worsening.

4. A mental illness is for life, it cannot be cured

Studies show that the majority of people with mental health problems improve or even recover completely. They can then participate fully once again in family life, society and work, even if some symptoms linger on.

5. The only way to treat a person with a psychiatric disability is to commit them or medicate them

The vast majority of psychiatric patients are treated as outpatients and are never hospitalized. Psychotherapy, physiotherapy, social rehabilitation courses and support groups are just some of today’s alternatives to medication and hospitalization.

6. Schizophrenics are violent and dangerous. They often kill people

The statistics speak for themselves: less than 1% of crimes are committed by people suffering a serious mental illness. There is no connection between a psychiatric disorder and the committing of a crime.

7. There are no effective measures for promoting accessibility among people who have a psychiatric disability

Since anxiety is one of the most common symptoms of a psychiatric disability, anything that helps create a reassuring atmosphere is welcome. We can also add:

⊗ Hiring patient, respectful staff who are trained in receiving people with disabilities;

⊗ Posting simplified, illustrated signs with easy-to-understand words, colors, symbols and icons;

⊗ Using visually different carpets or floor coverings, or tactile strips to point out the main pathways;

⊗ Comforting background sound with noise-dampening coverings;

Indoor navigation apps such as Evelity: it can suit every user’s profile and provides step-by-step instructions to serenely guide people within complex venues.

The Smartphone: a Revolution for the Blind and Visually Impaired!

The Smartphone: a Revolution for the Blind and Visually Impaired!

The Smartphone: a Revolution for the Blind and Visually Impaired!

 

How can you dial a telephone number on a completely smooth screen you cannot see? How can you type a message without embossed keys? At first glance, the smartphone should be synonymous with inaccessibility for blind people. And yet, it has become an indispensable companion for many of them: a trove of functions that pushes the boundaries of their independence.

How Can a Person with Vision Loss Use a Smartphone?

With the 2009 launch of its iPhone 3GS, Apple incorporated a screen reader called VoiceOver into its famous smartphone. Google quickly followed suit by adding TalkBack to Android.

To compensate for the lack of buttons, the principle is to touch or swipe the screen with a finger to hear aloud the item displayed on screen. Next, a specific gesture produces interactions with that item. The gestures are specific to each operating system (iOS or Android).

For people whose eyesight still allows them to read the screen, zoom options along with visual contrast and color settings improve their reading comfort.

As for entering text, the manufacturers have thought of everything. Options like virtual talking keyboard, dictation and connection to a regular or braille keyboard via Bluetooth are all available. The iPhone screen even converts into an actual braille keyboard for unrivaled quick typing.

And finally, those with visual impairment are often very fond of voice assistants like Siri and Google Assistant which allow them to avoid many complicated hand movements.

Which Smartphones Are Most Used by Blind People?

According to the results of the Screen Reader User Survey #7, 89% of people with impaired vision questioned use a screen reader on their cellphone. Of those, 69% use VoiceOver and 29.5% TalkBack. Apple’s success can be explained by both VoiceOver’s effectiveness and the number of apps developed on its platform that are made specifically for visually impaired people.

What Have Smartphones Changed in the Life of Blind and Visually Impaired People?

Quite simply, the vast majority of everyday actions that needed the help of a third person a few years ago can now be done on the phone.

There is one qualification, however. Mastering a smartphone when you cannot see anything or next to nothing is no simple task. It takes time, patience and dexterity. This is why the visually impaired, especially older people, do not all have access to this technological wonder. Yet, for the adept, the list of possibilities is long. They can obviously make phone calls or send messages (SMS or email), as well as manage their schedule and bank accounts, shop, read emails thanks to character recognition, book transportation or tickets to a show, talk on social media, read e-books, listen to music or podcasts, watch videos, play audio descriptions to TV shows or movies, read subtitles of a foreign film, use maps and calculate a journey on foot or by public transport, set off audio beacons, and even get help via a video call.

A Focus on Some Popular Apps for Visually Impaired People

The ability to travel is without doubt a principal issue for people who have lost their sight. Although GPS is still not precise enough to allow a person to find the entrance to a store, a bus stop or subway station without seeing, it is extremely useful to know where they are and in which direction they are going. Thus, people with visual impairments gladly use GPS apps for the general public like Maps or Google Maps. In addition to real-time directions, these apps offer the ability to prepare for a journey by going over the different stages from the comfort of their living room. Thinking ahead about a journey to an unfamiliar place is a very important step, especially since noise and the sense of vulnerability felt by some people with a visual impairment put them off from using their smartphone outside. Other transport apps, like Moovit and Transit, are also greatly welcomed. Thanks to GPS tracking, these apps can also alert a person that they are nearing their stop on a bus, train or tram—an invaluable option when announcements are not in service.

Other applications using GPS tracking have been developed specifically for the blind and visually impaired. BlindSquare, despite being expensive, is without doubt the most popular of them. However, it suffers from competition from Microsoft’s free application Soundscape. These apps describe surroundings and give alerts to intersections and nearby points of interest. They can also be used while the phone is in their pocket, which is a huge benefit.

Digital Accessibility is a topic for you? Check this article!

Another mention should go to Ariadne GPS, which allows real-time position tracking and browsing of a virtual map through the aid of VoiceOver’s speech synthesis. It is very useful for tracking a bus or taxi trip as well as for exploring a new neighborhood.
In the area of audio signs, MyMoveo triggers the latest generation of Accessible Pedestrian Signals (APS) aBeacon and audio beacons NAVIGUEO+HIFI manufactured by French company Okeenea. The desired message can then be chosen along with its language and volume.

The ultimate guide to accessible pedestrian signals. I want it!

Another revolution in the lives of those with a visual impairment comes from apps based on a support network that can be used at any time. Be My Eyes for example, as its name indicates, invites those with eyesight to lend their eyes for a moment to those who need them. Users get in contact through a video call. Choosing a shirt, finding out the use-by date of a yogurt or locating something that fell on the ground is then possible without having to wait for a friend or family member to pass by. For travel, Be My Eyes can also be used for finding a building’s entrance or a name on an intercom or letterbox.

Smartphones also have some multi-purpose apps for blind people. These include Microsoft’s Seeing AI and Google’s Lookout. These allow any printed document to be read by placing the phone’s camera over the document. But they can also detect light, recognize banknotes, colors and even images and faces.

Finally, to navigate indoor environments where satellite signals cannot be received, there is now the Evelity app. Already used in some places, it’s currently being installed in the Marseilles metro network in France where it will soon be available. It allows to go from point A to point B inside a station, but also between several stations. For example: a blind person can locate the metro platform from the entrance of a station and walk to the exit of the arrival station following the app’s voice instructions. Evelity works for everyone but adapts to the user’s disabilities to offer the best route.

The possibilities offered by smartphones today open up extraordinary opportunities for the inclusion of people living with a visual impairment. All that remains is for everyone to have access to these resources! You can help by passing this article on to everyone you know.

Accessible Pedestrian Signals (APS): a Century of Change

Accessible Pedestrian Signals (APS): a Century of Change

Accessible Pedestrian Signals (APS): a Century of Change

 

Accessible Pedestrian Signals come from a line of ingenious solutions first implemented for road users.

Indeed, once the first red-yellow-green traffic lights were installed, thoughts soon turned to how to help blind people safely cross the road. For a long time, it was thought that using a distinct sound to signify the pedestrian light was sufficient to allow a blind person to locate the crossing, decide the right moment to start crossing and make it to the other side without any peril. Current technology and our knowledge of what blind and visually impaired people today need have enabled far more effective systems to be put forward. Let’s look over the last one hundred years.

The First Acoustic Traffic Signal: For All Road Users

Did you know that the first traffic signals relied on sound? But they were not for blind people. At the start of the twentieth century, nobody was talking a lot about inclusive or accessible cities. However, the first traffic lights that operated on electricity and installed in Cleveland (U.S.A.) in 1914 emitted an audio signal. It was the same with most traffic lights installed in Europe during the 1920s. The reason was simple: the sound emitted was to alert road users to the changing of the lights since road users were still unaccustomed to light signals. With every change from red to green and vice versa, the signal emitted a ringing sound.

1920: First Acoustic Traffic Signal for the Blind in the United States

At the start of the 1920s, the first traffic lights with audio signals were installed for the benefit of people with a visual impairment. These systems generally used a bell or ringing sound during the green light. They were usually found close to schools for the blind but they were far from compulsory.

1960: Acoustic Signals Begin to Spread Everywhere

Although the first acoustic traffic lights for the visually impaired began to appear, albeit sporadically, in the 1920s, it was not until the 1960s when they became more widespread. At this time, the acoustic traffic light system that is the most commonly used today in the world appeared in Japan. From there it fanned out across the United States in the mid-1970s. In fact, it was inspired by bird calls. A speaker attached to the pole emitted a cuckoo sound at north-south crossings and a chirping sound at east-west crossings.

At the same time, other systems developed in Europe and Australia.

The limitations of traffic signals using bird sounds during the crossing period were quickly excoriated by representatives of the blind community. Firstly, the information passed on by the speaker was extremely limited. The difference between the cuckoo and the sparrow’s chirp was not enough to unequivocally distinguish between the crossings. The system implied that visually impaired people constantly knew their direction of movement. Moreover, the system did not allow a person to locate the edge of the cross walk when the pedestrian light was red since no sound was emitted at this stage. If the pedestrian crossing required a button to be pressed, there was nothing to indicate its existence. Finally, neighbors often complained about the noise from these systems that were constantly on.

1990: Silence of the Lights

Up to the 1990s, the acoustic traffic signals were constantly on, although they were sometimes interrupted during the night. The noise pollution caused by these devices began to become an environmental issue. Subsequently, several clicker systems that could be activated by a button on the post began popping up across Europe and Australia before moving onto the United States. Other systems developed that relied on touch: vibrating boxes in Switzerland and rotating cones in England. However, all these systems presented one undeniable problem for visually impaired pedestrians—they did not help in locating a crossing from a distance and required the person to search for the post, which was not always directly next to the crosswalk, to gain information on the color of the lights. The use of a push button, vibrating box or rotating cone in a public place also brought up issues of hygiene. Some push buttons emitted a regular beep to help a blind person locate the pole, but these “location beeps” could only be heard close by.

The ultimate guide to accessible pedestrian signals. I want it!

A Late Start by France but Early Leader in Innovation with Accessible Pedestrian Signals

At this time, France still had very few acoustic traffic signals installed, and usually only for pilot programs. For example, the city of Toulouse installed a signal using a ringing sound when the walking man appeared but only at certain often-used intersections. In 1993, EO GUIDAGE (now Okeenea) invented an accessible pedestrian signal that could be controlled by remote. In this way, blind and visually impaired road users did not have to search for the traffic signals to operate them. In fact, it was the signal that announced its existence by mentioning its color and the street on which it was installed. These remote-controlled signals gradually took over from other vibrating systems. The remote controls were distributed in towns and cities with the new signals. Subsequently, there appeared several types of remotes using different radio frequencies depending on their manufacturer. For many years, the use of the remote-controlled signals coexisted with the push buttons. But the push-button signals slowly fell by the wayside because they were often used incorrectly and became an annoyance to residents. Only Paris maintained them because of the number of foreign tourists to the capital.

In 2002, the French standardization board, AFNOR, established a standard for Accessible Pedestrian Signals (APS). The standard laid down the technical characteristics of the sound unit, the radio frequency used to trigger them and the content of the message provided. During the “don’t walk” stage, the signal must state “pedestrian red” followed by the street name, thereby limiting the possible confusion to visually impaired people where there are two crosswalks. For the “walk” stage, a continuous bell ring should be emitted. The French regulation required the installation of Accessible Pedestrian Signals for every new traffic light that went up and whenever road works were carried out at an intersection. Over 200,000 pedestrian lights have today been equipped with acoustic signals complying with the NF S32‑002 standard.

And Today, What Future for Accessible Pedestrian Signals?

There are many systems in the world that are used to allow the blind and visually impaired to know the right moment to cross the street: cuckoo, tweet-tweet, beep-beep, tick-tock, and even the traditional melodies in Japan. Countries also vary greatly in the standards used. However, the needs are universal! Acoustic performance, ease of use, customized information, limitation of noise pollution, ease of maintenance, reduction of costs, all these issues can be handled by today’s technology. Today in 2019, an acoustic traffic signal can not only be configured remotely but also triggered by a smartphone (a tool that is still underestimated for some reason).

In 1993, EO GUIDAGE invented an acoustic traffic signal that could be controlled by remote. In this way, blind and visually impaired road users did not have to search for the traffic signals to operate them.
