Many streets, due to noise restrictions, or public leisure policies (weekend bike paths, leisure streets, etc), have their traffic/turns restricted not only on sundays, but also during holidays.

I suggest that the restrictions screen on WME have added the "Holiday" flag. This flag would be checked against countryID, stateID and/or cityID (for national, state and city holidays) in a worksheet updated by champs, so that on these days the restrictions would take place.
