It is time that authorities concerned took proper steps to solve the traffic problems.
上面一句话中的concern 为什么加ed啊,我不太明白.
那这句话的后面为什么用took啊

这里是分词做定语,修饰authorities.
意思是：有关当局.
因为是做定语,修饰成分,所以应该用分词形式.
concerned表示“有关的”
concerned只是修饰“authorities”的,对句子其它部分没有影响.
至于took,这是一个固定用法：
It is (high) time that sb.did sth.所以要用过去时.
