Study On The GIS-T Midware Applied In Road Management

Nowadays, Chinese road transportation is very rapidly developing, but there are many problems with its management, for example, traffic jam, low level of management and running efficiency, all of which are seriously restricting and effecting the use of road transportation network, consequently it can't farthest serve popular living and national economic development. It is imperative to introduce and adopt new ideas and techniques to enhance road management, of which GIS-T is one of most important.GIS-T, is one type of GIS which is designed to study and solve the problems occurring in transportation, is a GIS applied in transportation scopes, is an important branch of GIS, is a tool which is used for modeling and analyzing such linear geographic features as road, railway, waterway, aviation, pipe network and communication circuitry, and is also a powerful means by which the movement, development of linear geographic features are being studying.After studying GIS-Ts development and many of its application instances, combining with current dominant information techniques, and the author consider GIS-T should be regarded as a toolkit dealing with gathering and processing traffic spatial data, spatial analysis as well as cartographic output, and as one of the core technical foundations of modern road management. On these basis, the author summarized, generalized and abstracted various GIS-T application in road management, then divided into several basic modules by its level and application purpose, so a cooperative and united architecture midware was gained.Thereafter, the GIS-T midware was widely integrated and applied in such daily management as road maintenance, road project, road administration, etc. and then, these subsystems can share and exchange road spatial data, road investigation data and road business data; GIS-T can cooperate with road business management systems; the road application models can utilize GIS-T in computation and evaluation. In general, the GIS-T midware provided the GIS-T's wide and deep application in road management with advanced technical architecture and pattern, so that GIS-T can indeed assist road management in all levels and all-around.
