The new system puts the weight of vehicles to use

Over the years, various researchers have developed systems in which the weight transferred through cars' wheels onto the road – or through pedestrians' feet onto the sidewalk – is used to generate electricity. These systems utilize piezoelectric materials, which convert mechanical stress into an electrical current. Such materials may be effective, but they're also too expensive for use in many parts of the world. That's why Mexican entrepreneur Héctor Ricardo Macías Hernández created his own rather ingenious alternative.  Read More

An algorithm developed by an MIT professor could be applied to a modified Adaptive Cruise ...

In 2007, mathematicians from the University of Exeter showed that the freeway traffic jams that appear to occur for no reason are actually the result of a "backward traveling wave" initiated when a driver slows below a critical speed. This sets off a chain reaction that ultimately results in traffic further down the line coming to a complete standstill. An MIT professor has now developed an algorithm that could be applied to a modified Adaptive Cruise Control (ACC) system to help eliminate such traffic jams.  Read More

An LCD built into the driver's windshield allows them to 'see through' the bus that they'r...

Nobody likes being stuck behind a large, slow-moving vehicle on the highway. Not only does it hold you up, but it's also difficult to see around, in order to check whether or not it's safe to pass. Prof. Michel Ferreira and his team from Portugal's University of Porto, however, have come up with what could someday be a solution to that problem. It's an augmented reality system that lets drivers see right through the vehicle that they're following.  Read More

SeeSense lights can reportedly determine the traffic conditions in which their user is cyc...

Although they may not be in common use just yet, there are already bike lights that automatically turn themselves on or off depending on ambient light levels. The SeeSense light, however, takes things a bit further. Not only does it respond to changes in lighting, but its makers claim that it can also determine the traffic situation in which the cyclist is riding, and adjust its output accordingly.  Read More

The new system being tested on the A6 highway, near Madrid

According to scientists at Spain's Universidad Carlos III de Madrid (UC3M), approximately five percent of vehicles on the road are responsible for about 90 percent of toxic vehicle emissions. Short of pulling each and every car over to analyze its tailpipe output, though, how does one go about identifying the offenders? Well, the UC3M researchers have helped design a system that images the emissions of individual vehicles in real time, on highways up to three lanes wide.  Read More

Jason Learmonth tells us about his bike, his gear, and the role of a motorcycle paramedic.

Jason Learmonth is a paramedic with a difference. Instead of an ambulance, he gets around town on a motorcycle that's kitted out with almost every piece of clinical equipment an ambulance carries. It's part of a trial that's putting two of these machines on the road in Melbourne, Australia, for three years to discover whether the bike's ability to get into hard-to-reach places and move through congested traffic is useful enough to make it a permanent part of the Ambulance service. I followed Jason around for an afternoon to capture some of his extraordinary working day in pictures.  Read More

TrafficCOM is a traffic-counting device intended for use by everyday people

Thanks to advances in technology, we now pretty much take it for granted that if we wanted to, we could start up our own digital publication, produce and distribute our own documentary, or fabricate our own small plastic items. One area that has yet to really become democratized, however, is traffic counting. Perhaps that’s not way up there on your personal list of things that you wish you could do for yourself ... but then again, you’re probably not part of the target market for TrafficCOM.  Read More

The Plug & Play Screamer is a more compact, easier-to-install version of the extremely lou...

Motorcyclists are already at risk when they’re traveling amongst cars, so it certainly doesn’t help that their bikes’ horns tend not to be very loud. That’s why biker and electrical engineer Peter Olt created the ear-splitting Screaming Banshee supplementary motorcycle horn. Now, he’s offering a smaller, easier-to-install model, known as the Plug & Play Screamer.  Read More

The proposed Virtual Traffic Lights system could make lights like these obsolete (Photo: S...

If you’ve ever seen two groups of ants meet up with one another on intersecting paths, you’ll notice that they don’t crash into each other. Instead, the larger group instinctively takes the right-of-way, followed by the smaller group – the same thing applies to bees and termites. Inspired by this behavior, Carnegie Mellon University telecommunications researcher Ozan Tonguz wondered if the same thing could be applied to traffic flow.  Read More

Volvo's new traffic jam assistance system autonomously follows the car in front

There are few things more frustrating than crawling along in stop/start traffic. Volvo has now come up with a system designed to make such monotonous trips a little more tolerable. At the push of a button, the traffic jam assistance system will automatically follow the preceding vehicle in slow-moving lines of traffic traveling at speeds of under 50 km/h (31 mph).  Read More
