[字彙] Traffic rate clerk

[NormaJean (benevolence)]

我想請問traffic rate clerk這是什麼樣的職業= =?
因為在google上我找不到答案，
如果拆開來看的話，traffic rate是速率的意思，
但是還是不大懂這個職業確切是在做什麼的。
請高人指點迷津>"<，拜託了。

謹附上原文：
        worked as a traffic rate clerk for the Continental Engineering Company
of Pittsburgh, Pennsylvania.  In this position I started as an assistant in the
traffic ddpartment and later prepared and filed claims for overcharges.
