59 A p p e n d i x B This appendix presents basic procedures to run DynusT– FAST-TrIPs in the DynuStudio environment. Assume all FAST-TrIPs files are located in the same DynusT scenario folder, including all input files, program executables, and inte- gration scripts. All outputs will be saved in the same folder. Figure B.1 shows the DynusT–FAST-TrIPs run window. • Transit network To enable FAST-TrIPs transit, a network must exist and the Transit button must be checked. The Start Time is the transit service starting time in real clock time (min). In Figure B.1, the start time is 11 a.m. or 660 min. The transit dwell times can be set to use the existing values from previous runs or be reset to zero. • FAST-TrIPs configuration Click the FAST-TrIPs button to open DST-FSTRPConfig .dat from the current folder. As shown in Figure B.2, this file contains two parameters: 44 maxIter—maximum number of iterations for the feed- back runs; and 44 fstFlag—a flag with a value of 1 or 0 to indicate whether FAST-TrIPs will be run in the integration run. If 0 is given, only DynusT runs will be performed. • FAST-TrIPs–DynusT feedback Check the FAST-TrIPs–DynusT feedback button to enable the integration run, which is controlled by Python script dst_ft_ex.py, which is located in the current scenario folder. The script is composed of the following parts: 44 Execute DynusT run. 44 Execute FAST-TrIPs run. 44 Import dwell times from ft_output_loadProfile.dat and prepare TransitDwellTime.dat to be used in the next DynusT run. • Import final dwell times The final dwell times from FAST-TrIPs can be imported into DynuStudio by using analysis option 20, shown at the bottom of Figure B.3. Figure B.4 shows the transit display option in DynuStudio. After the final dwell times have been imported, they can be displayed in proportional cir- cles at stops on the transit layer as shown in Figure B.5.
