"Bilateral" adaptive cruise control could help reduce traffic jams

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

See-Through System turns view-blocking vehicles transparent

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

Sensor-packing SeeSense bike lights adapt to lighting and traffic conditions

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

Camera system "sees" toxic emissions from individual vehicles in real time

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

A day in pictures: Melbourne's motorcycle paramedics

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 opens up traffic counting to everyone

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

Insect-inspired virtual traffic lights could replace – or augment – the real things

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
