粗集在交通事故黑點(diǎn)成因分析中的應(yīng)用

交通事故黑點(diǎn)的形成原因多種多樣，每一個(gè)事故多發(fā)點(diǎn)都有其形成的最大誘因。作為交通安全管理工作的重要任務(wù)，交通事故黑點(diǎn)的鑒別與改善是預(yù)防交通事故發(fā)生、減少交通事故損失的有效手段。該文針對(duì)交通事故多發(fā)點(diǎn)成因的復(fù)雜性和多樣性，提出通過(guò)粗集來(lái)對(duì)公路交通中的不利因素進(jìn)行篩選，找到形成事故多發(fā)點(diǎn)的最大誘因，從而有針對(duì)性地進(jìn)行整治，能夠有效地節(jié)約時(shí)間和費(fèi)用，避免不必要的人力、物力浪費(fèi)。

The traffic black-spot cause of formation is very complex, and every black-spot has the most important inducement for itself. The identification and improvement of black-spot, as an important task of traffic safety management, are very effect measures to reduce the traffic accident frequency. For the complexity and diversity of the black-spot cause of formation, we find a method based on the rough set to determine the most important inducement of the black-spot, then we can repair the inducement in effect and save more time and money.
