TSIS-CORSIM and TRANSYT-7F are now distributed together as one combined product. TRANSYT-7F release 11.33 is now automatically installed by the TSIS 6.3 installation CD. TRANSYT-7F enhances the traffic signal analysis functionality of CORSIM in the following ways: 1) import CORSIM files and optimize their signal timing, 2) automatically generate input files for NETSIM, 3) compute level of service for NETSIM intersections, 4) generate time-space diagrams for NETSIM, and 5) generate summary text reports for CORSIM (network-wide outputs also reflect FRESIM results when applicable).
