• Description:
  A microcomputer that communicates to traffic measuring devices (Golden River and TRIDAQS) via RS 232 port is equipped to emulate a 3278 workstation. Due to the emulation software and hardware type and the host computer program, data files could not be downloaded or uploaded. The mainframe's program was modified and a different emulation package employed now enables file transfers (after project ended). New lap top microcomputers configured as TRIDAQS units now collect and process travel time data in four districts.
