If somone were finally to solve the problem of matching up traces to ways, we would be in a position to extend that to identifying some map errors, such as missing ways, or changed road layouts.
how to present this information in a useful way is a diferent task, but worth keeping in mind. Could I sugest splitting your proposal into to distickt projects: track/way matcher; system to use that data for trafic flow.
