MICROCOMPUTERS IN TRANSPORTATION. FEDIT USER INTERFACE FOR FHWA'S TRAF-FRESIM MODEL

The FEDIT Data Input preprocessor for FHWA's (Federal highway Administration) microscopic freeway simulation program, FRESIM, is described. The latter is a freeway design and operations analysis tool capable of analyzing, in great detail, large complex, or unusual freeway geometric configurations, and can help identify complicated and detailed interactions among different design, control, and traffic variables. It is noted that an efficient method of preparing the input data, while minimizing data input errors and the typical 'code-execute-debug' cycle, is thorugh the use of FRESIM Freeway EDITor program -FEDIT.
