HCS™

HCS™ > Overview

HCS7™ (Release 7.2.1) is available.

This release of the Highway Capacity Software (HCS7) includes updated modules to implement the Highway Capacity Manual 6th Edition (HCM6) procedures for Signalized Intersections, Urban Streets, Alternative Intersections, Roundabouts, Freeway Facilities, Basic Freeway Segments, Freeway Weaving Segments, Freeway Merge & Diverge Segments, and Multilane Highways, while the methodologies for Two-Way Stop Control, All-Way Stop Control and Two-Lane Highways are unchanged.

New

The Freeways module now models the cross-weaving effects that can reduce general purpose lane capacity for on-ramp traffic accessing managed lanes and managed lane traffic accessing off-ramps, which also facilitates demand variance within the managed lane facility. The Streets module now includes a Signal Timing and Phasing report for multiple signals on one page. Passenger-Car Equivalents are now adjustable in the Roundabouts module.
