Travel Time and Speed Statistics for Links Containing Locks 16 through 20

This is an Excel spreadsheet that records the travel times/speeds of each trip through a lock in the range of Lock & Dam 16 through Lock & Dam 20 in the Upper Mississippi River. Each lock is part of a three sublink set: a sublink upriver from the lock, the lock itself, and a sublink downriver . A table of links used by the study, a link map, and heat maps are also included.本数据集为一份Excel电子表格，记录了美国密西西比河上游16号至20号船闸大坝（Lock & Dam）范围内，每一次过闸行程的耗时与航速。每一座船闸均对应一组由三个子链路组成的集合：分别为该船闸上游的子链路、船闸本体，以及该船闸下游的子链路。本数据集还附带了本研究所用的链路统计表、链路地图与热力图。
