About the TSIS-CORSIM™ 6.3

Summary of New Features

Streets Editor and Freeways Editor. Based on the Urban Streets and Freeway Facilities modules from HCS, these new editors use basic volume and timing data from the user to automatically construct complex simulation networks within seconds.

High Occupancy Toll (HOT) Lanes. The new version of CORSIM supports different HOT lane pricing algorithms, monetary value of time for each vehicle type, HOT pricing output data, and specification of vehicle types permitted to use HOT lanes in each time period. In addition, the user can specify a percentage of transponders for each vehicle type, and numerous calibration parameters to customize vehicle behaviors near HOT lanes. Sample input files for HOT lanes are automatically installed to the “TSIS Projects” folder. Documentation for this feature is available in “Managed Lanes.pdf”, and in the CORSIM Reference Manual.

Advanced Toll Plazas. CORSIM now supports different types of toll payment in each lane, vehicle type restrictions in each lane, and the percentage of vehicles using each payment type. In addition, the toll plazas now allow all settings to vary between time periods, and numerous calibration parameters to customize vehicle behaviors near toll plazas. TRAFVU 6.3 has been modified to indicate advanced toll plazas, and provides color coding to indicate payment types for each vehicle. Sample input files for advanced toll plazas are automatically installed to the “TSIS Projects” folder. Documentation for this feature is provided in the CORSIM Reference Manual.

Interactive Lane Alignment in TSIS Next. TSIS Next users can now drag-and-drop entire roadway sections to achieve better upstream/downstream lane alignment. Endpoints are used to control intersection and node alignments, and the midpoints are still available to affect curvature. Alternatively, a pop-up dialog is available to manually enter the X/Y feature point values. This feature is used to make vehicle animation and roadway displays more accurate in TSIS Next, but does not affect vehicle animation and roadway displays in TRAFVU.

Adaptive Cruise Control (ACC). CORSIM now allows the user to specify the percentage of advanced technology vehicles in the traffic stream, plus car-following time headways for each ACC driver type.

New Input Screens in TSIS Next. TSIS Next has been updated for version 6.3; with added support for ACC, HOT lanes, and advanced toll plazas.

Increased Number of Lanes allowed at Interface Nodes.

Minor Improvements and Bug Fixes. Fixed the control delay calculation on entry links in NETSIM; fixed a problem with freeways that split into two branches and then rejoin downstream; improved some of the input error checking logic; updated the CSV output format to handle 9-lane approaches; corrected a bug in spillback checking that occurred when the right receiving link and the right-diagonal receiving link were the same link and a single lane served both right and right-diagonal turns; fixed a problem in the calculation of travel times and average speeds on NETSIM interface links; auxiliary lanes can now be included on FRESIM interface links.
