摘要
北京作为我国最重要的铁路交通枢纽中心之一,历年来北京与全国各城市间的最短铁路时间是研究北京至各个城市可达性的空间格局变化以及全国铁路发展变化的重要基础。作者根据《全国铁路旅客列车时刻表》(1996、2003、2009)和中国铁路服务中心发布的数据和信息的收集、整理、计算、汇编得到以北京为中心的全国226个城市铁路交通最短时间距离变化数据集(1996、2003、2009、2016)。该数据集包括北京和全国226个城市的地理位置、北京到这些城市的空间距离,1996、2003、2009、2016年北京到这些城市铁路交通最短时间、时空转换参数、基于时间距离转换后的空间坐标等。该数据集存储为.xlsx格式,908条记录,数据量为187 KB。
Beijing is one of the most important railway transportation hubs in China.The shortest railway travel times from Beijing to other Chinese cities throughout the years offer an important basis for studying the changes in the spatial pattern of Beijing’s accessibility to other Chinese cities and the development of and changes in China’s national railways.In the present study,the data were collected from the 1996,2003,and 2009 China Railway Passenger Train Timetables and the official website of the China Railway Service Center(www.12306.cn).By sorting,calculating,and compiling these data,a dataset of changes in the shortest railway travel times from Beijing to 226 Chinese cities(1996,2003,2009,and 2016)was produced.Specifically,the dataset contains the spatial coordinates of 226 Chinese cities,their spatial distances from Beijing,their shortest railway travel times from Beijing in 1996,2003,2009,and 2016,their time-space conversion parameter values,and their deformed geographical coordinates.The dataset is stored in.xlsx format,contains 908 records,and has a size of 187 KB.
