No matter how the rta allocates the pie , however , the current pot of money seems woefully inadequate .

不管区域交通署如何分配它的预算，现在的资金似乎是不够的。

Although the usda research found that in most cases total trade rose following an rta , it also found some evidence of " trade diversion " .

虽然usda研究发现：在大多数案例中随着区域贸易协定达成总贸易量会有所上升；但同样也发现了一些“贸易分歧”存在的证据。

It may be that by gearing up for trade ( investing in distribution networks , for example ) , firms within an rta are able to exploit efficiencies that boost trade more widely .

这或许是因为通过升级贸易网络（比如说投资分销渠道），区域贸易协定中的企业能充分地利用各方的效率，更广泛的促进贸易活动。

Chicago 's regional transportation authority ( rta ) , which covers the six counties of the metropolitan area , is supposed to promote better planning and links among the city 's system and a pair of others that run suburban train and bus networks . But it has clearly come up short so far .

芝加哥的区域运输署负责着市区隶属的六个县，理应为城市交通以及其他一些运营郊区的铁路和公路交通提供更好的规划和联系，但是到目前为止它做的明显不够。
