regarding Chapter 20: All-way Stop-Controlled Intersections

Does anyone know of any All-Way-Stop-Control intersection software that uses the HCM 2010 methodology or can analyze a three lane approach? I downloaded the spreadsheet and it does not have any of the formulas in it. I have reentered the formulas but I would prefer to have something that is accepted in the field.

The software that I use is also limited to two lanes per approach although the HCM says that three lanes on an approach can be analyzed. Using spreadsheets to analyze an AWSC intersection is difficult, so I wouldn't try that unless you are ready for a big undertaking. I don't know of software that can anlyze three lanes per approach, but hopefully all of the HCM software packages will be able to do that some time soon.
