“Talking’”cars to reduce collisions

The concept of “Talking” cars is soon to be a reality, the project is under development  by scientists from the University of Bologna.

These scientists have formulated software that allows cars “communicate” with one another on the road. Similar technology may have been applied previously, but scientists claim that this time the car would be able to know what had happened kilometers ahead.

Tests show that this technology can lower motorway accidents by 40%. The decrease in accidents emerged during computer simulations which were elaborated in a paper published in the journal Computer Networks.

Car maker Toyota will carry out the road tests of the software in August 2011 on the streets and motorways of Los Angeles.

While  telecommunications and informatics in cars has been in use for some time, the Italian researchers have added one more ingredient.

The ultimate intention is to link up all the cars on the road via WiFi, either by setting up a WiFi-enabled sensor in a car, or by downloading the software on to a smartphone.

The “talking” is caused through acceleration sensors inherent in the cars that transmit an alarm message in unnatural conditions such as when a vehicle is involved in a collision.

Team leader Professor Marco Roccetti said that the study could have a major impact on society – particularly “in terms of human lives and societal costs”.

This alarm could disperse down the chain of vehicles in a relay so they could safely stop a long way before they reach the accident spot.

If this project turns out to be a success, it could very well be a step closer towards the notion of “Smart Cities”, where everything is interconnected and computer-controlled, from traffic lights to the “talking” cars, thus reducing accidents and providing the drivers some much needed relief.

据阿根廷《21世纪趋势报》7月13日报道：“会说话”的车即将成为现实，意大利博洛尼亚大学的科学家们正在研制这个项目。
 

他们已经开发出一种软件，它能使行走在路上的车辆“相互交流”。虽然先前已经尝试过这种技术，但科学家称，这次车辆将可以“知道”数公里以外发生的事情。
 

计算机模拟测试结果显示，这项技术能减少40％的高速公路车祸。该研究发表在《计算机网络》杂志上。
 

日本丰田汽车制造商将于今年8月将在洛杉矶大街和高速公路上对这种软件进行路面实地测试。
 

尽管车用远程信息技术问世已有一段时间，但意大利的科学家又在其中添加了一个新的组件。
 

其最终的目标是把道路上所有汽车通过无线网络联系起来，可以在车内安装传感器，或者也可通过把这个软件下载到智能手机上来实现。
 

“交谈”主要通过安装在汽车里的加速传感器来进行。当一辆汽车被撞后，传感器就会捕捉到这种异常变化，并向其他车辆发出警报。
 

该研究团队负责人马尔科•罗切蒂教授说，此项研究可能会对社会产生重大影响，特别是在生命安全和社会成本方面。
 

警报信息会通过互联网汽车以接力的方式传播，这样就可以确保其他车辆安全停靠在距离事故地点较远的安全地带。
 

这个项目倘若能够成功实施，那么就意味着向“智能城市”这个概念又迈进了一大步。包括交通信号灯到“会说话”的车，所有事物都相互连接并通过计算机控制，这不仅可以减少交通事故，还可以让司机松口气。
