1868-2019: a Brief History of Traffic Lights

 

Red, green, yellow… three-color traffic lights are now a daily part of every person’s life. But it wasn’t always like that.

While their presence in city centers is now being questioned, they still fulfill an essential function by regulating the competing flows of traffic at an intersection.

Let’s take a look at a hundred and fifty years of history!

The First (Disastrous) Trial in England

December 10, 1868: the official birth date of the world’s first traffic light. It was installed at Parliament Square in London. The system was composed of two mobile signs attached to pivoting arms that were manipulated by a lever. The post was topped with a gas-lit semaphore to ensure visibility. But it was short-lived. Less than two months later, the traffic light exploded, killing the police officer who worked the signs.

The world had to wait 46 years until electricity use became widespread before the first dual-colored traffic light, using this new energy, was installed in Cleveland in the United States. Detroit and New York added yellow between red and green in 1920. The traffic lights that we now know were born and became the norm throughout the world.

1920-1930: Traffic Lights Up Europe 

In 1923, the first mechanical traffic light using electricity was installed in Paris at the intersection of Boulevard de Strasbourg and Grands Boulevards. Most of Europe’s largest cities soon followed suit: Berlin in 1924, Milan in 1925, Rome in 1926, London in 1927, Prague in 1928, Barcelona in 1930… And the system was exported to Tokyo in 1931.

 Accessible Pedestrian Signals: A Century of Change: read our last article!

Standardization and Regulation in the 1930s

The first Convention on the Unification of Road Signals was signed in Geneva on March 30, 1931. Its goal was to increase road traffic safety and facilitate international movement by road through a uniform system of road signals. The majority of signs that we recognize today were defined through this treaty. Traffic lights with three colors (red, yellow, green) became the standard.

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

Specific Lights for Pedestrians 

Pedestrian signals quickly appeared after the tri-colored traffic lights. At the start, they took various forms but matched the colors used by vehicles: red and green. Round, square or rectangular, they often gave the instruction “Wait” in red and “Walk” in green. In 1974, regulations introduced the figures that we know today, brought in because of a concern for foreign speakers and international standardization. However, the installation of pedestrian signals was initially overlooked due to their cost and their disputed usefulness. In Paris at least, since 1955, they have been systematically installed at the city’s intersections.

Systematic Use of Traffic Lights Since 1950

Road traffic rose dramatically between 1950 and 1980, creating a need for an increasingly stricter regulation of traffic and the near ubiquitous use of traffic lights. In 2011, the largest French cities had an average of one traffic light-controlled intersection for every 1,000 inhabitants.

 

While they have long been considered the best solution for managing competing traffic flows, traffic lights are today suspected of fostering accident-prone behavior. This is the reason why many cities are reconsidering the systematic use of traffic lights and are preferring other methods for reducing the speed of vehicles. At the same time, they want to offer better circulation conditions for non-motorised mobility and public transportation. Out of this desire have emerged new light signals for giving these methods right of way. The issue today is to ensure that the most vulnerable road users remain safe and maintain their independence to travel in an environment whose points of reference are in flux.

European Accessibility Act: What Will Change?

European Accessibility Act: What Will Change?

European Accessibility Act: What Will Change?

 

Eighty million Europeans living with a disability will benefit from more accessible goods and services at competitive prices! The European Accessibility Act was adopted by the European Parliament and Council. Member States have a six-year transition period before having to fully enforce it. Among the areas it covers are information for travelers, vending machines, banking services, e-commerce, e-books and emergency numbers. It is a small revolution for those with a disability and a huge challenge for businesses.

Towards Free Movement of Accessible Goods and Services

The European Accessibility Act has been on the agenda since July 2017 and has two principal goals:

⊗ Improve the daily life of the elderly, disabled people and people with reduced mobility throughout the entire European Union (80 million people at a conservative estimate); and

⊗ Facilitate the circulation of accessible goods and services by removing barriers created by divergent laws among the various Member States.

Businesses should see a reduction in costs from the standardization of accessibility laws throughout Europe. Furthermore, they will gain access to a large market for their products and services.


As for those living with a disability, they will benefit from a wider range of accessible goods and services at more competitive prices. Benefits are also expected for them in the areas of education and job access. Their expertise in accessibility should see a rise in demand and their professional integration will be eased by software accessibility.

Principles of Universal Design

Under this new European directive, goods and services should be designed in a way that allows them to be used by everyone, regardless of their particular difficulty:

⊗ color-blindness, poor vision or complete blindness;

⊗ poor hearing or profound deafness;

⊗ speech problems or total mutism;

⊗ problems in gripping or absence of physical strength;

⊗ reduced mobility;

⊗ cognitive difficulties (reading, gesturing, memory, etc.).

Essentially, every good or service must be “perceptible, usable, understandable and sturdy.” This means:

⊗ An action should be possible by using different sensory methods (voice message, speech recognition, visual display, touch);

⊗The transfer of information should also be possible via various sensory methods;

⊗ Visual contrasts ought to be considered;

⊗ The font can be increased;

⊗ It should be possible to change the volume and speed of audio messages;

⊗ Actions requiring strength or precision should be limited;

⊗ Latency time between two actions ought to be open to configuration;

⊗ There should be information on accessibility functions;

⊗ And, of course, assistance technologies should be compatible (screen readers, audio support, voice command, etc.).

From Ticketing Machines to E-commerce Platforms, Many Areas Are Covered!

The directive mainly applies to digital services and related equipment:

⊗ Computers and operating systems;

⊗ Ticketing machines, check-in machines;

⊗ Smartphones;

⊗ Audiovisual services, digital television and related equipment;

⊗ Telephony services;

⊗ Public transportation ticketing and related information (road, rail, air, sea or river);

⊗ Bank services;

⊗ E-books; and

⊗ E-commerce.

Now that the European Accessibility Act has been adopted by the European Parliament and the European Council, only its publication in the Official Journal remains. After that formality, Member States will have three years to transpose the directive into national law and another three to apply it. Some associations representing disabled people have criticized the text’s lack of ambition, lamenting how it does not apply to transportation infrastructure, streets and buildings. It also includes many restrictions for small businesses. Let’s hope however that the new European Accessibility Act will be a positive impetus for the extension of universal design to all areas of everyday life!

Digital Accessibility: Why? For Whom? How?

Digital Accessibility: Why? For Whom? How?

Digital Accessibility: Why? For Whom? How?

 

Even though the digital world has now become an intricate part of our lives, we still only have a fuzzy idea of what digital accessibility is. We often think it’s enough to provide blind people with an audio description of images on websites. This article takes a quick look at the situations and areas concerned along with the resources available to make digital tools accessible to everyone.

What Is Digital Accessibility?

Digital accessibility is the provision of access to information and, more importantly, to all functions of a digital tool to the entire population, irrespective of a person’s specific needs.


Whether temporarily or for life, every user can be affected by a visual, auditory, motor, psychiatric, intellectual or cognitive disability. Such disabilities have impacts on the ability to read, enter text, recognize images, make a precise gesture or even locate important information.

What Areas Does Digital Accessibility Encompass?

Digital accessibility applies to all tools based on digital technology. Of course, this includes the Internet but there are many other tools, all essential for our daily lives in the twenty-first century:

⊗ Software and software packages;

⊗ Mobile apps

⊗ Documents (PDFs and others);

⊗ Human-computer interaction (HCI), information terminals, ticketing machines, etc.;

⊗ Connected objects.

Likewise, the aspects of daily life affected by digital accessibility are continually expanding. We use digital tools for researching information and communicating through email or social media. We also use them to manage our time, go shopping, perform administrative tasks, learn, relax, monitor our exercise and health, manage our accounts and many other things. We should not forget all their uses in relation to travel: GPS, multi-modal trip planning, public transportation schedules, ordering a ride, searching for nearby restaurants, etc.


And people living with a disability do not want to be left behind. They want the same range of choices that is open to those without a disability.

Some Basic Advice for Successful Digital Accessibility

Without going into too many details, there are good practices that should be followed to ensure the digital service you offer can be used by everyone. Here are some of them:

⊗ Check compatibility with W3C standards;

⊗ Differentiate between types of content (e.g. by style sheets);

⊗ Pay attention to visual contrast;

⊗ Structure information (headings, areas, paragraphs, etc.);

⊗ Describe images through optional text;

⊗ Use keyboard shortcuts;

⊗ Subtitle videos;

⊗ Transcribe audio and video files;

⊗ Label the fields on forms;

⊗ Use alternatives to captchas.

How to Improve Digital Accessibility?

We have selected some resources that you might find useful for the project that you are working on:

⊗ Color Contrast Analyzer;

⊗ The W3C Markup Validation Service;

⊗ Web Content Accessibility Guidelines (WCAG);

⊗ Microsoft Accessibility;

⊗ Accessibility overview for Android Developers;

⊗ Accessibility on iOS for Apple Developers.

How to Test it?

You can download NVDA’s open-source screen reader free of charge to test the accessibility of a website, application or Windows-based software. The screen reader is widely used by people with impaired vision. For Android or iOS apps, you can just activate the accessibility options on your tablet or smartphone, in particular their respective screen readers TalkBack and VoiceOver. Where possible, we recommend using a panel of testers who have disabilities because they would be the best experts on their condition.

Remember that just as in the case of a building’s physical accessibility, digital accessibility costs much less when it is incorporated into the initial design. You therefore should not forget this aspect in your design briefs and consider it especially when upgrading.

8 Clichés About Blind People

8 Clichés About Blind People

8 Clichés About Blind People

 

Maybe it’s because sight is the sense most used by humans or maybe it is because of our deep-rooted fear of the dark, but blindness provokes both dread and curiosity. There are many preconceived ideas about blind people. Here are some that we will now debunk.

1. Blind people have a sixth sense

False. Blind people have one fewer sense, not an extra one.

The word blind simply means unable to see. Over the course of history, blind people have sometimes elicited irrational fears and inordinate admiration at other times, and almost always some form of fascination. Why is a sixth sense often attributed to them? If they sometimes give the impression that they have perceived some preternatural sign, it is only because being deprived of the primary sense used by humans obliges them to use their other senses to a far greater extent than those with sight generally do.

2. Blind people hear better

False. Blind people hear neither better nor worse than the rest of the population.

However, hearing is the principal sense they use to compensate for their lack of sight. With the same auditory acuity, a blind person can capture more sound information than a sighted person. It is first of all a matter of attention to the soundscape and its interpretation. After all, they rely on accessible pedestrian signals to know when they can safely cross the street. So, you should not be surprised if a blind person hears something that you completely missed. Quite simply, your concentration was on something else, probably what was in front of your eyes.

3. All blind people can read braille

Again false. Only about 10% of blind people can read braille. Far from all of them!

In the majority of cases, blindness occurs after the age of learning to read. This disability affects a large majority of people over 60. So, it is rare that such people would have access to learning braille. Furthermore, the sense of touch can be altered through manual work, an illness or medical treatment. Even when learned early on, braille requires regular practice or it can be lost. It’s not easy to find access to documents in braille on a daily basis.
For the blind people who have mastered it, braille is, nevertheless, a key tool for social and professional inclusion.

4. Braille is a type of foreign language—very difficult to learn

False. Braille is just an alphabet, a code for transcribing letters.

It is a touch-based writing system, where each character comprises a combination of embossed dots. Its 64 different dot combinations are enough to transcribe all letters of the alphabet, including accented letters, figures and punctuation. While mastering braille requires a honed sense of touch, it is, on the other hand, very easy to decode a braille text by sight using an alphabet and some basic rules.

Everything You Have Always Wanted to Know on Braille Mysterious Writing

5. Blind people have no concept of colors

It all depends on the age the person became blind.

Obviously, those who have never seen colors will have difficulty imagining them. But the majority of blind people were not always blind. They maintain their visual reference throughout their lives. In any case, even people who were born blind are able understanding the codes connected to colors: red or green light, blue sky or water, green leaves turning red in the fall… There is no need to see to understand the underlying meaning of colors.

6. Blind people don’t dream

False. They do, like everyone else!

Dreams are made up of impressions captured during the day. Sight is the dominant sense among humans, so dreams are mostly composed of a stream of images. For those who have never seen, they do not dream in images. For people who were born blind, their dreams contain impressions originating from other senses: hearing, touch, smell and even taste. For those who could see earlier in life, their dreams can also retain clear images as before or images altered due to the degeneration of their sight.

7. Blind people cannot use a computer

False. Of course they can. Fortunately, there are many adaptations to computers allowing blind people to use a computer.

Screen readers are software programs that read aloud all that appears on a computer screen through a voice synthesis: entered text, web pages, menus, dialog boxes, etc. These programs include keyboard shortcuts allowing the blind user to move from one element to another as a sighted person can do visually. They can also be connected to a braille display, a sort of tablet that creates embossed dots representing the different letters during reading.

These tools, however, are expensive and require intensive training to be able to use effectively. Their effectiveness also relies heavily on how much the software developers and webmasters incorporated digital accessibility into their design.

Artificial Intelligence and Accessibility: Examples of a Technology that Serves People with Disabilities

8.      Blind people cannot use a smartphone

False. This may be more surprising than the fact that they can use a computer.

With their completely smooth screen and near absence of buttons, it is not readily obvious that blind people would be able to use smartphones. But smartphone manufacturers have considered this issue in depth and today offer apps like VoiceOver for iOS and TalkBack for Android. These apps vocalize all actions made on the screen and allow interaction through adapted gestures.

Making Public Transport Information Accessible to Disabled People?

Making Public Transport Information Accessible to Disabled People

 

Planning a journey, knowing the waiting times at bus stops, knowing where to get off, taking correct action in the case of disruption—using public transport requires having access to information at every step along the way. The task, of course, is far more complicated for people living with a disability, whether motor, sensory or intellectual. This article offers a list of solutions that can be used to provide accessible public transport information to all types of passengers.

The Needs of Disabled Passengers Regarding Accessible Public Transport Information

“Passenger information” encompasses all information transmitted to transport network passengers at every stage of their journey. Passenger information can be provided in different paper or digital formats and can be checked remotely or at stations and stops or even on board vehicles. Even though such information is for all travelers, providing it to those living with a disability is far trickier.


Disabled travelers need to receive the information in real time and in an appropriate format in order to:

⊗ Prepare their itinerary according to their mobility (location of stops, transportation network accessibility);

⊗ Know in real time the operating condition of adapted equipment (elevators, escalators, etc.);

⊗ Be informed about the next step in their journey (checklist);

⊗ Know what to do in the case of a service disruption.

Their specific needs are complicated during irregular occurrences (breakdowns, strikes, detours, stops not served, etc.). People with hearing loss can rarely get information on disruptions since it is usually announced orally. Those with visual impairment lose their bearings and find it difficult to find an alternative itinerary. People with a motor disability may find themselves unable to take an alternative means of transportation because of physical obstacles.

Finally, people with an intellectual disability will also have difficulty understanding the information, making a decision and finding new reference points. Another significant aspect is that the stress caused by disruptions to all travelers is far more burdensome on disabled passengers due to their particular difficulties and their sometimes heightened sensitivity (psychiatric disability, autism).

Trip Preparation with Easy-to-Use Trip Planners

For a person with a disability, preparation is key to a successful trip. Some years ago, trip planning relied on maps and schedules jotted down on paper, and they still are essential to some people, but the digital alternatives available today have made planning far more efficient. Transportation operators usually provide a trip planner on their website, supplemented by a mobile app.

However, these trip planners should fulfill the following conditions if they are to be usable by a disabled person and respond to their needs:

⊗ The web or phone interface must conform to digital accessibility standards (usable with a screen reader, adaptable to the user’s display settings, etc.).

⊗ The options for the trip planner must include accessibility criteria: elevators, escalators, level access, etc.;

⊗ Stations and stops must be possible to locate on a map and by their actual address, which must be fully written out (for those who cannot read the map and so that it can be entered into a GPS).

To facilitate the mobility of everyone, all information on the transportation networks should be made public so that it can be integrated into multi-modal trip planners. In fact, the use of apps or trip planners that are specific to single cities is often an obstacle.

Written or Audio Materials Designed for Different Disabilities

Despite the development of digital technologies, physical materials can still be of great service to many transportation passengers. This is why it’s important to make simple maps or large-font timetables available to passengers. London, for example, has a wide variety of subway maps; they come in contrasted colors and audio format. Some maps only show the above-ground network for those with claustrophobia. Another example is Toulouse (France), which offers an audio description of its subway stations.

Visual and Audio Traveler Information Points

Departures, connections and arrivals, every step in a journey has its stop. At every stop, people need accessible public transport information.


Traveler information points are illuminated signs at bus stops, and tram or subway stations. These signs notify passengers of the waiting time and any possible disruptions to a line serving the stop.
But what use are these to a visually impaired person? The information points have to be in audio format, possibly through the use of a remote control or a smartphone. This function has two advantages. Firstly, the on-demand audio provides illiterate people with the same information everyone else receives. Secondly, the activation of the sign by remote also allows visually impaired people to precisely locate the stop and confirm that they are where they want to be.


This solution has already been rolled out across numerous cities around the world, such as San Francisco, Auckland, Toulouse, Lyon and Prague.

Read our article: Obstacles in Public Transport: What Solutions for Physical Disability?

Disruption Announcements in Audio and Writing

In the event of disruptions (breakdowns, strikes, re-routing of lines or just a simple change of platform), the information is usually given to passengers over a PA system located in the vehicles or at the stop. Deaf people are left noticing the change in attitude of the passengers around them yet oblivious to the reason. The situation becomes more distressing for them when they soon realize there is a problem but have completely missed out on any solution that has been proposed. It is therefore essential that such information be also given on screens installed for this purpose.

SMS Alerts on Disruptions: Universal Accessibility

For disabled people, disruptions to their means of transportation can cause plenty of stress and added difficulties. That’s why such situations need to be anticipated, more so than for other travelers.
SMS alerts are already available on many urban transport networks, providing real-time information on disruptions affecting the entire network or only those lines selected beforehand by the user according to their usual routes.
This system is aimed at all transportation users. For a person living with a disability to also benefit from this technology, it should be ensured that subscription to the service does not act as an obstacle. Adherence to digital accessibility standards and a simple procedure remain crucial.
It ought to be noted that this system of SMS alerts should not replace other methods of providing information about disruptions. After all, those without a cell phone or who have not registered for the service would remain in the dark otherwise.

Visual and Audio Announcement of Next Stop

In all public transportation, the announcement of the upcoming stop is an essential piece of information for passengers, all the more so if they are not familiar with the route. This information is often available on an illuminated panel. But it must also be given orally. Obviously, this is for those with a visual impairment but, more generally, it is for anyone who cannot read whether due to illiteracy or simply because of where they are sitting.

Some smartphone apps alert users to the moment when they should request their stop.

Innovative Smartphone Apps for Connecting Passengers

The use of smartphones is widespread and has opened up new possibilities for individual travel. Some applications offer to connect a disabled person with one-off voluntary helpers, whether for a minute, an hour or more.
A good example of this type of app is BeMyEyes, which allows blind or visually impaired people to get visual help via a video-conversation with any one of a number of volunteers ready to lend their eyes for a few minutes.
As for mobility, Faciligo is a French travel buddy platform allowing people with reduced mobility to find a travel companion for any type of journey on public transportation.
The idea is to connect travelers with reduced mobility or a disability and even elderly passengers with able-bodied travelers thereby improving transportation access to people who cannot travel alone. For the support provided, the companion receives a discount on the price of their ticket.

Workshops on Transportation Networks for the Most Vulnerable Users

Help from another person is sometimes indispensable in preparing for a trip so that a disabled person to set off independently on public transportation. Some transportation operators have established workshops or courses allowing disabled people to learn and understand the network.


In Paris, the transport operator RATP organizes Mobility Workshops. These workshops were originally aimed at passengers with intellectual disabilities, but they soon expanded to schools and have received high praise from participants.

These are great examples of accessible public transport information that you can also implement in your network to help your users.

The addition of audio information to visual information and vice versa, the setting up of accessible digital services, the use of phone apps, and on-demand community support are just some of the numerous local initiatives that have sprung up to open up information access to all passengers. The main issue today remains standardizing the different sources and making the information known to everyone so that every person can reap the benefits.
