美髮明車載報警系統提前識別闖紅燈者

MIT researchers have developed an algorithm that can "detect" drivers who're likely to drive straight across a red light - before they do so.

The monitor "watches" deceleration and distance from a light - and "guesses" which cars are likely to break the Highway Code.

Crucially, the software can provide two seconds' warning if someone else is about to shoot across a crossroads - enough time for other drivers to hit the brakes.

Jonathan How, the Professor of Aeronautics and Astronautics at MIT, says "smart" cars of the future may use the system to help drivers anticipate and avoid potential accidents.

The researchers tested the algorithm on data collected from an intersection in Virginia, finding that it accurately identified potential violators within a couple of seconds of reaching a red light — enough time, according to the researchers, for other drivers at an intersection to be able to react to the threat if alerted.

Compared to other efforts to model driving behavior, the MIT algorithm generated fewer false alarms, an important advantage for systems providing guidance to human drivers.

The researchers report their findings in a paper that will appear in the journal IEEE Transactions on Intelligent Transportation Systems.據英國《每日郵報》12月1日報道，麻省理工學院的研究人員開發出一種運算程序，能夠在司機可能闖紅燈之前對其行爲作出偵查判斷。

這種監視器會通過燈光來“觀察”車輛的減速和距離——由此“猜測”哪些車可能會違反交通規則。

關鍵在於，該軟件會在有人試圖快速穿過十字路口時發出兩秒鐘的警報——這樣其他的司機就能有足夠的時間踩下剎車。

麻省理工學院航空航天學教授喬納森·豪說，未來的“智能”汽車很可能會採用這種系統，來幫助司機預見和避免可能發生的事故。

研究人員根據從弗吉尼亞州的一個十字路口收集的數據對這項運算程序進行了測試，結果發現，該程序能夠在駕駛者到達紅燈前的幾秒鐘內準確識別出可能違規的人——據研究人員稱，這幾秒足以讓十字路口的其他司機在發出警報時對潛在的威脅做出反應。

相較於其他模擬駕駛行爲的嘗試，麻省理工學院提出的這一運算程序較少發生誤報，該程序的一個重要優勢還在於，它給人類駕駛者提供了指導。

研究人員已將該項成果整理成論文，將發表在《IEEE智能交通系統》雜誌上。(IEEE：美國電氣和電子工程師協會)
