Bus routes - are they worth mapping?

I saw that a select few bus routes are mapped in Tel Aviv, not necessarily the most frequent ones and not always correctly.
Is fixing and augmenting the data worth investing in, or is some automatic mapping from GTFS data planned for the future?

Mapping bus routes manually - isn’t very easy and fast task…
Given the fact that we have whole GTFS information (bus stops and routes) it will be easier to import them all at once (otherwise will need to perform some sort of merging of old and new data)
You can monitor GTFS related thread (http://forum.openstreetmap.org/viewtopic.php?id=16738) for any news about import process.
