| 摘要： | This paper seeks to illuminate the status of transportation safety and risk for large quantity shipments of spent commercial reactor fuel and mixed and hazardous wastes by examining road and rail accident and vehicular travel data from the mid 1990s. Of special interest are the effect of speed limit changes on controlled access expressways and the possible effect of season to season climatic variations on road transportation. Improvements in railroad technology and infrastructure were found to have created a safer overall operating environment for rail freight shipments. Evidence was found of an increase in accident rates of heavy combination trucks in states that have raised highway speed limits. Cold weather increases road transportation risk, while conditions associated with higher ambient temperatures do not. For rail transportation, both hot and cold temperature extremes are associated with higher accident rates. |
