While Mcity can be used to simulate(模拟) many real-life road conditions, it cannot help test gestures drivers use to communicate their intention to other drivers, pedestrians or cyclists. To find a solution, the US car manufacturer Ford, with researchers from Virginia Tech, firstly considered using text as a way to communicate the car's intention, but decided it would probably not work universally. The option of using symbols was also discarded, because research showed that the majority of people did not have a good understanding of what they meant. Finally, the researchers settled on light signals. A white light warned that there were no humans in the car. A slow blinking one indicated that the car was coming to a stop, while a rapidly flashing light cautioned passers-by that the car was about to accelerate. Then came the big challenge—testing the signals on the real road. "We need to try out this new lighting to communicate the intention of the vehicle, but if you've got a driver behind the seat, you still have natural communication between humans," said Andy Shaudt, who led the Virginia Tech research team. "So we need to make it look like a driverless car." The team designed a car seat costume(服装) that the driver would wear to cover his or her face and upper body. Of course, the driver could see very clearly. The researchers then equipped the car with cameras to capture human reactions to a light bar on the windshield(挡风玻璃), which flashed one of the three signals when appropriate. Six drivers, all keeping their hands low on the wheel so as not to be detected, took turns to test driving the car through the busy streets. The overall reaction to the flashing lights was very encouraging. Who knew costumes could be useful for more than Halloween 11.What did t ... ...
