【大数据助力警示“逆行车”】高速路上总有些开错路的“笨蛋”怎么办?德国汽车供应商Bosch公司发明了一个软件包,它能基于大数据分析车辆的正常运行方向,通过激活路标指示及时警示走错路的司机,如果没有指示路标,它能够通过智能手机和车载广播提醒,降低事故发生频率。

The traffic accident you least want to be in is a collision with a car moving in a direction opposite to your own.

Even though such wrong-way collisions account for only about 3 percent of accidents on divided highways in the United States, according to a 2013 reportby the U.S. National Transportation Safety Board, they are 12 to 27 times as likely as other accidents to result in death. It makes sense to go to some trouble to prevent them.

Bosch, the German auto supplier, has done so with a software package that compares a car’s direction with a Web-based database of roads and quicklyalerts the driver of wrong-way movement. It even goes so far as to stop the car, giving oncoming vehicles a bit more of a chance to get out of the way.

At the same time, the system alerts those oncoming cars using a cloud-based, anonymized system. It can activate roadside signage; even if such signage isn’t around, it can send an alert to drivers via their smart phones or car infotainment systems.

That’s critical because in many cases the driver who’s going the wrong way may be unresponsive to any warning. Studies have shown that such drivers are often impaired by disease, old age, or alcohol. Worst of all are the ones who go the wrong way on purpose.
