Road

It’s not unusual for automotive designers to test virtual models of cars on virtual models of bumpy roads. The model of the car, of course, represents an actual proposed vehicle. As for the road, however... where does that model come from? In the case of new technology used by Buick, it’s a millimeter-precise recreation of an existing, physical road.  Read More

Last month, we told you about an experiment with air-purifying concrete that was recently conducted in the Netherlands. Researchers resurfaced 1,000 square meters of a busy road with concrete paving stones that contained titanium dioxide (TiO2), a photocatalytic material that removes automobile-produced nitrogen oxides (NOx) from the air and converts them into nitrate with the aid of sunlight. When the air was tested up to one-and-a-half meters above those stones, NOx levels were found to be 25 to 45 percent lower than above regular concrete on the same road. Now, a similar study is underway in Germany, and is already showing promising results.  Read More

Luckily there aren’t many countries that drive on the opposite side of the road and share borders. However, they do exist, such as China, which drives on the right, and the former British colony of Hong Kong, and former Portuguese colony of Macau, both which drive on the left. This can pose an interesting problem for engineers and road planners, but Dutch architectural firm, NL Architects, has come up with a bridge with a twist – a concept that not only puts the drivers on the correct side of the road physically, but helps reinforce that fact visually to help get the drivers into the mindset of driving on the opposite side of the road.  Read More

More and more cars are integrating driver assistance features that help do things like avoid collisions, keep a safe distance from other vehicles, or even parallel park. There are also Lane Departure Warning systems that use onboard cameras to keep the driver from drifting out of their lane. But what happens if the roadside markings are worn away, or covered with snow or mud? Norwegian research organization SINTEF has come up with a solution called WayPilot – a system which uses sensors embedded in the asphalt and a shaking steering wheel to alert drivers before they stray too far off course.  Read More

What’s more frustrating than an accident with a fellow motorist? Trying to work out who is at fault. Aiming to do away with such disagreements and improve overall driver security is the Kolimat Roadscan DTW 1.0 Camera system. Equipped with a dual lens in-car camera that records up to 12 hours of audio and video onto an SD card, the unit also takes still pictures at regular intervals and features full GPS and Wi-Fi capabilities. But with a function that disables erasing of data for events that measure above a preset “G” force, you had better hope you’re not at fault…  Read More

Like most things, ice can be a blessing or a burden depending on the circumstances. It’s perfect crushed in a drink on a hot summer’s day, but can wreak havoc when it collects on roads, power lines and aircraft in freezing temperatures. A University of Pittsburgh-led team has found a way to reduce these dangers by developing a nanoparticle-based coating that can be easily applied to impede the buildup of ice on solid surfaces.  Read More

Taking driver-assist technology to the next level is the “Smart Stop” system currently in development by Mercedes Benz. The wireless safety system, which allows intersections to communicate with vehicles, would automatically cause a car to stop at a red light should a driver fail to heed it.  Read More

It’s starting to look like roads will become much more than simple thoroughfares made of concrete and asphalt in the not too distant future. As we’ve seen, work is already underway to embed them with solar panels and piezoelectric generators to generate electricity. Now engineering company Ingenieurgesellschaft Auto und Verkehr (IAV) is looking to embed them with electrical conductors that would “refuel” the electric cars of the future while they are driving or parked.  Read More

Idaho-based Solar Roadways founder Scott Brusaw is excited that his company has a received a USD$100,000 U.S. Department of Transportation (DOT) grant to develop further his prototype that turns roads in giant electricity-generating solar panels. Apart from providing energy to power our homes, street lighting and so on, the roads could contain thousands of embedded LEDs to provide better street signage and make driving safer. He also believes the solar panel roads could last up to three times longer than the current petroleum-based asphalt surface and even be heated in winter to discourage dangerous ice build ups.  Read More
