GIS functionality enhances Crash Analysis solution


Gdynia, Poland, August 21, 2007: Netherlands-based road safety specialist VIA has used the TatukGIS Internet Server for the GIS functionality in its web-based automobile crash reporting and analysis solution, ViaStat-Online. ViaStat-Online allows police, municipalities, road safety/management organizations, research, and consulting firms to register, report, monitor, and analyze crash data. The accurate reporting, monitoring and analysis of historical crash data enables detailed studies of specific locations, monitoring of developments over multiple years, and answering of questions from the general public. The conclusions drawn from crash data analysis are useful to set policies and measures to prioritize road/street infrastructure investments, optimize enforcement efforts, and target groups for education/information campaigns.

GIS functionality provided by the TatukGIS Internet Server to the ViaStat-Online will enable crash data to be linked to the digital road network so that the data can be managed and presented in the form of digital maps. In addition to the various map presentation options, the GIS functionality enables more in-depth analyses using geographical selections from the map.

For example, crash data can be rendered in relation to road features, such as the number of crashes in relation to speed limits. Alternatively, data relating only to specific geographical crash concentrations, routes, or map areas can be selected for in-depth analysis. Detailed information for any crash can be accessed directly via the map. Rendered map images can be exported as Word or PDF files for inclusion in consultancy reports. The digital map data itself can be exported as shapefiles of various formats, e.g., *.SHP, *.MIF, *.DXF, *.GML, *.KML, etc., for use in other GIS.

The ViaStat-Online solution uses digital road/street map data provided by Tele Atlas, one of the world’s leading companies in this area. The Tele Atlas files are dynamically loaded and displayed by the TatukGIS Internet Server so that the map shape-files for any given zoom level and location are loaded.
