A perliminary discussion on the study of transportation network''s geo-informative Tupu of urban system
城镇交通网络信息图谱研究刍议

Thanks to the cooperation among the scientists from many countries across the world, the year 2000saw human finished drawingthe map of his own genome. This very accomplishment bringsnot only an increasing momentumto the knowledge of life sciences and biological technology but also great impetus and enlightenment to other fields of sciences. Under such circumstances, Prof.Chen shupeng, an Academician of CAS, took the lead in puttingforward the concept of Geo informative Tupuand attached great importance to the related researchissues and possible practical uses ensued from it. And he argued that these would definitely be of great importance to the development of both geographic science and future of the country. Following him, scholars of geography and many other disciplines began their studies on this promising topic. Based onall these, this paper probes into the connotation of geo informative Tupu and the basic characteristics that it shares with transportation network, touches on the applications of Tupu that are actually found in the field of transportation, analyses the possibility that Tupu will give to the study and improvement of transportation network when it is used efficiently as the most important information source of transportation network and combined correctly with latest technology such as RS, GIS, GPS, ITS etc. And after all thesehave been done, the paper forecasts several major aspects that Tupu will benefit transportation network when its right conception is fully understood and scientifically used.
