Quick Reference Guide


If you're interested in simply knowing how Synchro incorporates the HCM 6th edition methodologies without all the extra information, this section is for you. One word of caution, though.  Take the time to read this document at least once. The limitations of the HCM 6th Edition methodologies are critical elements to understand as you compare it to other analysis methodologies. It is Trafficware's goal to match the methods as they are described in the manual.
