Try this, test it, but don't expect too much reality, there are several aspect for traffic direction even the wind.
The AFCAD with the release, have the correct direction as you suggest, but in FSX is doing the opposite.
In this attach I change the direction, some aircraft do taxy in the right direction other they don't.
If you want to make changes, you can open AFX_PHNL file with ADEX or other AFCAD tools.
