Methodology step by step 1. Create accident tables in ArcView GIS 3. Create accident theme using ArcView GIS 4. In this study, dynamic segmentation capabilities made GIS the tool for linking accident data with the highways. The accidents as point events were associated with the highway at measure locations.
Dynamic segmentation associates multiple sets of attributes to any portion of a linear feature.
A physical clean up of the arc-node topology should be done to insure linear connectivity. A route is a linear feature on which attributes can be located. The section table is the intermediate table connecting the RAT to the AAT and gives the route measures. An event is an attribute that can be tied to the route system based on measure, for example, accidents as point events can be associated with the route at measure locations 1.7, 3.2 and 7.4 mile. In Arcedit, routes and sections can be edited using editfeature command.
