| 摘要： | This reports main objective is to analyze the change in rates and modal costs for shippers, commodity industries and ports prior to, during and after the fifteen week lock outage and to determine the impacts on the environment in the form of energy consumption and emissions production prior to, during and after the lock outage. Waterborne movements are one of the more economical and cost-efficient methods of transport among all modes of transportation, comprising a key component of the Pacific Northwest multimodal transportation system. Commodity shipments moving through this river system were recently halted for 15 weeks during the winter of 2010-2011 for an unprecedented extended lock outage. |
