For Germany the Free TMC Location Code List is managed by state authorities (BAST). 
Only points can be added and not deleted. TMC has a limit of IIRC 64K defined
points between which traffic problems can be signaled.

So there is map data - long term - long valid. Then you have the TMC LCL 
list which basically is aswell long term and long valid. 

Then you get VERY LITTLE data transmitted via FM radio (RDS, TMC)
which then signals the mobile client some traffic jams etc.

When talking about "traffic database" you may refer to something like
google traffic which is basically a real time traffic speed database. 
Its vast amount of data and you'll need a lot of mobile clients.
I dont think the community is capable of a) paying for the central
services and b) deploy the necessary amount of mobile clients giving
feedback.
