摘要：
Geographic Information System for Transportation (GIS-T) is an integrated technology of GIS and Transportation,which deals mainly with linear features-only have one set of attribute.Linear Reference System (LRS) is a onedimensional system.An unknown linear feature can be expressed directly according to the known linear features' position information and those relatively position relationship of each other without x,y coordinates.It is an intuitive way to associate multiple sets of attributes to portions of linear features.Dynamic Segmentation (DS) segments the route dynamically,and storages the attributes of all the routes in an unattached table (event table).Combining Linear Reference System with Dynamic Segmentation in GIS-T,which is more convenient to query,display and analyze the linear feature's attributes.

摘要：
Geographic Information System for Transportation (GIS-T) is an integrated technology of GIS and Transportation, which deals mainly with linear features-only have one set of attribute. Linear Reference System (LRS) is a onedimensional system. An unknown linear feature can be expressed directly according to the known linear features' position information and those relatively position relationship of each other without x, y coordinates. It is an intuitive way to associate multiple sets of attributes to portions of linear features. Dynamic Segmentation (DS) segments the route dynamically, and storages the attributes of all the routes in an unattached table (event table). Combining Linear Reference System with Dynamic Segmentation in GIS-T, which is more convenient to query, display and analyze the linear feature's attributes.
