How often does Google Maps update traffic?

The images in google Maps (and google Earth) are updated on a continuous basis. The update cycle is typically twice a month but only a handful of areas are updated at a time.

It's hard to say exactly when an area will be updated because some areas may be updated more frequently than others (just because that data is more readily available). While most images are no more than 3 years old in high resolution areas, low resolution imagery in some areas may be older.

It takes months of post processing new imagery before they go online so bulk updates usually happen about every 2 weeks. google Maps and google Earth share the same backend image database and are updated together.
