Clear way to reduce traffic accidents

ON MONDAY MORNING, agglomerate fog caused a traffic accident involving 28 heavy-duty trucks in Zhumadian, Central China's Henan province, which killed nine people, and seriously wounded nine others. Beijing Youth Daily comments:

Seven days ago, another traffic accident caused by agglomerate fog in Liaocheng, East China's Shandong province, involving 21 automobiles, claimed two lives and left nine people seriously wounded.

Such fatal traffic accidents caused by agglomerate fog happen frequently in winter almost every year, as such fog is very local phenomenon, and it is hard to detect and forecast.
