摘要

Space positioning information model and logic model of traffic facilities arernestablished, by studying the internal organizational structure of Geodatabase model.rnOn the basis of the data of Jilin province expressway, the spatial database is designedrnin detail with seamless integration of database management model, by analyzing therncharacteristics of spatial database of traffic facilities. The traffic management systemrnis realized by secondary development of GIS, the software of which includesrnVB.NET, ArcGIS Engine and ArcSDE. The system implementation verifies thernsuperiority of the GIS model, provides a scientific and efficient management toolsrnfor traffic facilities management.
