Abstract: The MIDAS (Michigan Dimensional Accident Surveillance) System has been developed to provide accident analysis capability. A microcomputer version of MIDAS is being developed to make the model available to cities and counties for use on their road systems. Converting MIDAS into a microcomputer version presents a series of new challenges, much more than simply downloading and recompiling the source version of the programs. MIDAS requires large amounts of data concerning roadway geometry, traffic operations, traffic flow, and accident experience. Some of these data must be obtained from the local agency and the codings and reference systems converted to be compatible with the other data. Updating and transferring the data is critical, especially since MIDAS is sensitive to the accuracy of the data. Output reports must be redesigned for microcomputers with slower printers.
