What is the license and support arrangement with HCS+T7F?
HCS+T7F is distributed as an office license that includes technical support (automatic updates, downloadable updates, toll-free telephone assistance, data file review, etc.) for the first year. Thereafter, an annual support subscription must be maintain to continue these services, but no more upgrade fees are required.
Does the upgrade from HCS+ to HCS+T7F add new modules, upgrade only changed ones, or is it a completely new set?
This release comprises a complete installation of HCS+ (release 5.3) implementing all approved changes to the procedures defined in the 2000 Highway Capacity Manual (HCM 2000) to date, adding HCS+Interchanges to automate the methodology in the recently approved HCM Chapter 26 for Interchange Ramps Terminals and integrating TRANSYT-7F (release 11.2) with the ability to import HCS-Signals and HCS-Interchanges data files for optimization and one-touch CORSIM animation.
Do I need to uninstall the previous version(s) of HCS?
HCS+T7F is a separate installation and does not automatically uninstall HCS+ (or any previous version). Although uninstalling the previous version(s) is recommended to avoid conflicts and confusion for most users, allowing multiple versions to co-exist on one computer can be managed if there is a need. Some issues to be aware of include: double-clicking on a data file within Windows Explorer will typically load it in the latest version; right clicking on a data file within Windows Explorer to use ‘Open With’ can show multiple versions without information to tell them apart; and information like agency data, default file paths, some default data, recent file list, window position, etc. is stored in the Windows registry, and changing this for one version will likely affect the others.
What are the minimum computer requirements for this version?
HCS+T7F is a typical Windows installation and the system must meet the following minimum requirements including Windows 2000 or newer, 128MB RAM, VGA+ Monitor and 300 MB Hard Disk space available. This will be a completely new installation, separate from any existing version. The installation program will present a license agreement, which must be agreed to for the installation to proceed.
Are there any issues with running HCS+T7F in Windows Vista?
No issues have been discovered in testing or reported by users, except for the requirement to download a free file from Microsoft to enable the on-board Help system as noted in the Known Issues below.
What does the integration of TRANSYT-7F (T7F) add to the package?
TRANSYT-7F is a signal timing optimization tool that combines a state-of-the-art optimization process (including genetic algorithm, multi-period, and direct CORSIM* optimization) with a state-of-the-art macroscopic simulation model (including platoon dispersion, queue spillback, and actuated control simulation).

Do I have to have TSIS-CORSIM installed for the one-touch animation feature to work?
Yes, TSIS-CORSIM is not a part of the HCS+T7F package and must be installed separately for this feature to work. HCS+ and T7F both generate CORISM input files for automatically running CORSIM to produce the output files necessary for creating the TRAFVU animation.
Where is the new Interchanges module applicable?
This analysis covers the unique relationship between two signalized intersections controlling the ramps from an intersecting freeway. It will analyze diamond, six partial cloverleaf and single-point urban interchange designs, accounting for internal queuing, additional lost times, etc. to generate levels of service for each origin-destination movement.
Does the median type make a difference in a Two-Way Stop-Controlled analysis?
The computation of two-stage gap acceptance differs for the minor-street thru movements depending on the type of median. A “Raised Curb” median assumes the minor-street thru can utilize this storage to perform the movement in two steps. A “TWLTL” median will assume the minor-street thru movement will be accomplished in one stage.
Why won’t my formatted report print on one page?
Since these reports use the Internet Explorer for display and printing, adjustments may need to be made there for these reports to print on one page. To suppress the automatic header and/or footer, simply blank the appropriate field(s) in the “File > Page Setup” screen. Setting margins to 0.25″ on this screen is also advisable. You may also have to reduce the text size in View > Text Size.
Why does the last field with data sometimes not get used in the calculations or saved in the file?
Users must be sure to hit Tab, Enter or click into another field before viewing or printing results to ensure the last entry has been recognized. When a data file is saved, the last entry is automatically stored.
