SECOND GENERATION CONTROL FORTRAN SOFTWARE. URBAN TRAFFIC CONTROL SYSTEM (UTCS) SOFTWARE SUPPORT PROJECT--VOLUME I

The Second Generation UTCS has been converted from its machine dependent language to FORTRAN Enhancements to the system included an improved technique for determining when traffic signal timing pattern recomputation should occur; a change to provide for maintenance of user defined signal phase splits or offsets; a recoding of the link/phase correlation; a modification in the offset optimization algorithm to properly compare optimum solutions for altermate cycle lengths; and numerous corrections to the UTCS data base. File maintenance for the source programs was developed, and all source images are in easily-modified magnetic tape formats. A source language editing program was added to the system library for the 2GC FORTRAN system. Documentation for routines which remain unchanged from the original 2GC was updated to reflect new documentation standards. /Author/
