This report summarizes progress made in Phase II of the GIS-based Accident Location and Analysis System (GIS-ALAS) project. Phase II efforts build on Phase I activities, which were focused on improving the current PC-based Accident Location and Analysis System (PC-ALAS) used by the Iowa Department of Transportation (Iowa DOT); these improvements were realized through the development of a GIS-based system that facilitates advanced spatial query and display capabilities in a graphical environment. Phase II efforts then focused on the refinement and enhancement of GIS-ALAS in both Explorer ALAS and ArcView ALAS, and on the use of GIS-ALAS in specific applications. This report documents several Phase II activities including the refinement and enhancement of GIS-ALAS using a list of suggested improvements; changes in the data conversion processes; a specific case study; and several technology transfer efforts. Several appendices with more detailed information are provided at the end of the full report.
