Highway Capacity Software

HCS+^TM (Release 5.4) is available.

This latest version of HCS+ adds the Single-Point Urban Interchange (SPUI) to the other seven interchange types analyzed within the Interchanges module.  The Help system has been converted to HTML for added functionality, compatibility with Windows Vista, and a separate Users Guide for each module.  The DAITA program received significant changes to better accommodate collecting demand data for oversaturated signalized intersections, included the ability to record end-of-period residual queues for translating into turning movement demand arrival flows.
 
HCS+T7F still provides seamless access to TRANSYT-7F, now in version 11.3 as the profession’s most powerful signal timing optimization.  This combined software package provides for advanced signal timing optimization for intersections, arterials or networks using TRANSYT-7F. 

Of course, HCS+ faithfully implements the procedures in the Highway Capacity Manual (HCM) including all approved changes to date for Signalized Intersections, Unsignalized Intersections, Urban Streets, Multilane and Two-Lane Highways, Freeway Sections, Weaving Areas and Ramp Junctions.  HCS+ also includes Warrants (MUTCD), LOSPLAN (Florida DOT) and DAITA (turning movement counts), as well as one-touch animation using CORSIM (sold separately).
