Here are four futuristic new designs for pedestrian crossings

More than 7,000 accidents occur at pedestrian crossings every year in the UK, according to data from the Transport Research Laboratory. And there are many factors which impact upon the safety of pedestrians as they cross the street, including their position relative to traffic and how crowded a crossing is.

So far, officials have mostly sought to improve the safety of pedestrian crossings through minor changes to design, with technological developments taking a backseat. In the future, however, smarter technologies may become the primary strategy for making crossings safer, and various high-tech crossing projects are already being trialled around the world.

Here are four of the most notable.

1. The Starling Crossing

One of the most prominent is the Starling Crossing, which is short for STigmergic Adaptive Responsive LearnING. It’s being designed by a London-based company called Umbrellium for insurer Direct Line, and it’s currently at the prototype stage.

Instead of being painted on the road, the markings for this crossing are made of LEDs, which enables them to change according to traffic conditions. If a large group of pedestrians is crossing, the crosswalk widens. If there are no pedestrians, it disappears.

The system uses cameras to monitor car, foot and bike traffic and direct everybody accordingly. It uses machine learning to inform its decisions and adjusts the crosswalk to the route that pedestrians typically take to cross the street.

2. The Line of Sight

Direct Line is also working with a second company, Mettle Studio, on another crossing project called the Line of Sight – a strip of red LEDs that light up when pedestrians are crossing the street. The red lights warn cars anytime someone steps onto the crossing. Once pedestrians cross the street, they flash and then go out entirely.

Like the Starling Crossing, the Line of Sight uses cameras to detect pedestrians and activate the LEDs.

3. FLIR Systems Pedestrian Detectors

Another tech company that’s looking to revolutionise crosswalks is FLIR Systems, which recently acquired the company Traficon, a maker of intelligent traffic systems.

FLIR offers smart city products such as the TrafiOne, a sensor that monitors vehicle and pedestrian traffic and uses that information to control traffic signals. In addition to a camera, this device uses thermal imaging, which enables it to more easily detect pedestrians in the dark. If the system detects pedestrians waiting to cross the street, it can extend the red light for vehicles.

4. Traffic Tech Pedestrian Switch Pads

Another way to detect pedestrians is with pressure-sensitive switch pads, such as those from Australia-based company Traffic Tech. The pads offered by the company are only 3.5 mm tall and can adhere to existing pedestrian ramps. The pad detects when a pedestrian is standing on it and sends a signal to control traffic lights. It can also cancel the signal if the pedestrian steps off of the pad. The device can even detect the direction a pedestrian is walking because it contains multiple rows of buttons that are activated individually.

 


Implementing Smart Technologies

We already employ some technologies at our pedestrian crossings, such as buttons and sensors – although some question whether these devices actually help pedestrians cross the street faster. At any rate, the technology we currently use is fairly basic, and the more advanced tech is mostly in the prototyping and testing phases.

Implementing these advanced devices into crossings is slow work, since they must undergo stringent testing to ensure safety. Eventually, though, we’ll likely see smart crossings in cities around the world improving pedestrian safety.

Crossings won’t be the only part of the road that will be smart in the future. In fact, other aspects, such as vehicles, are already incorporating smart technologies. In the future, nearly every element of traffic will communicate with one another: self-driving cars, traffic lights, road signs, roads themselves, crosswalks and even pedestrians and cyclists will be able to communicate with each other over a network of sensors and internet-connected components.

This increased connectivity could help to improve safety for pedestrians and drivers and also increase the efficiency of how we get around by improving traffic flow and reducing congestion. Smart technologies are expected to be able to reduce travel times by between 16 and 36 percent.

Building this system, however, will be a long and challenging process. Although it’s already getting started, it’ll be a while before we have fully connected smart roadways. Until then, we should continue the work that’s ongoing in designing better crossings that make life safer and more convenient for pedestrians.

 
 
 
 

CityMetric is now City Monitor! Come see us at our new home

City Monitor is now live in beta at citymonitor.ai.

CityMetric is now City Monitor, a name that reflects both a ramping up of our ambitions as well as our membership in a network of like-minded publications from New Statesman Media Group. Our new site is now live in beta, so please visit us there going forward. Here’s what CityMetric readers should know about this exciting transition.  

Regular CityMetric readers may have already noticed a few changes around here since the spring. CityMetric’s beloved founding editor, Jonn Elledge, has moved on to some new adventures, and a new team has formed to take the site into the future. It’s led by yours truly – I’m Sommer Mathis, the editor-in-chief of City Monitor. Hello!

My background includes having served as the founding editor of CityLab, editor-in-chief of Atlas Obscura, and editor-in-chief of DCist, a local news publication in the District of Columbia. I’ve been reporting on and writing about cities in one way or another for the past 15 years. To me, there is no more important story in the world right now than how cities are changing and adapting to an increasingly challenging global landscape. The majority of the world’s population lives in cities, and if we’re ever going to be able to tackle the most pressing issues currently facing our planet – the climate emergency, rising inequality, the Covid-19 pandemic ­­­– cities are going to have to lead the way.

That’s why City Monitor is now a global publication dedicated to the future of cities everywhere – not just in the UK (nor for that matter just in the US, where I live). Our mission is to help our readers, many of whom are in leadership positions around the globe, navigate how cities are changing and discover what’s next in the world of urban policy. We’ll do that through original reporting, expert opinion and most crucially, a data-driven approach that emphasises evidence and rigorous analysis. We want to arm local decision-makers and those they work in concert with – whether that’s elected officials, bureaucratic leaders, policy advocates, neighbourhood activists, academics and researchers, entrepreneurs, or plain-old engaged citizens – with real insights and potential answers to tough problems. Subjects we cover include transportation, infrastructure, housing, urban design, public safety, the environment, the economy, and much more.

The City Monitor team is made up of some of the most experienced urban policy journalists in the world. Our managing editor is Adam Sneed, also a CityLab alum where he served as a senior associate editor. Before that he was a technology reporter at Politico. Allison Arieff is City Monitor’s senior editor. She was previously editorial director of the urban planning and policy think tank SPUR, as well as a contributing columnist for The New York Times. Staff writer Jake Blumgart most recently covered development, housing and politics for WHYY, the local public radio station in Philadelphia. And our data reporter is Alexandra Kanik, whose previous roles include data reporting for Louisville Public Media in Kentucky and PublicSource in Pittsburgh, Pennsylvania.

Our team will continue to grow in the coming weeks, and we’ll also be collaborating closely with our editorial colleagues across New Statesman Media Group. In fact, we’re launching a whole network of new publications, covering topics such as the clean energy transition, foreign direct investment, technology, banks and more. Many of these sectors will frequently overlap with our cities coverage, and a key part of our plan is make the most of the expertise that all of these newsrooms combined will bring to bear on our journalism.

Please visit citymonitor.ai going forward, where you can also sign up for our free email newsletter.


As for CityMetric, some of its archives have already been moved over to the new website, and the rest will follow not long after. If you’re looking for a favourite piece from CityMetric’s past, for a time you’ll still be able to find it here, but before long the whole archive will move over to City Monitor.

On behalf of the City Monitor team, I’m thrilled to invite you to come along for the ride at our new digs. You can follow City Monitor on LinkedIn and on Twitter. If you’re interested in learning more about the potential for a commercial partnership with City Monitor, please get in touch with our director of partnerships, Joe Maughan.

I want to thank and congratulate Jonn Elledge on a brilliant run. Everything we do from here on out will be building on the legacy of his work, and the community that he built here at CityMetric. Cheers, Jonn!

To our readers, on behalf of the City Monitor team, thank you from all of us for being such loyal CityMetric fans. We couldn’t have done any of this without you.

Sommer Mathis is editor-in-chief of City Monitor.
