Depends what you mean by vehicle tracking systems.

Coincidentally enough, just this minute I've been walking around, scratching 
my head and considering what would be involved in building a generic position 
deduction framework which could accept input from any source of 
positioning 'hints', take into account any sources of error and give the best 
possible guess it can on your position.

Such hint sources might include GPS, car odometer hookup, accelerometers, 
gyroscopes, cameras with image recognition algorithms...

The obvious first step would be attaching an error value to every single 
number in the simulation and calculating those in parallel to the positioning 
calculations. But then you'd possibly need quite complex heuristics for what 
to do when several of your sources disagree to a degree greater than the 
error margin.

I imagine papers have been written on this subject, but I have yet to find 
them. Any input on this ugly brain-dump of mine would be welcome.

ps- If you hadn't already guessed, I think such a piece of software would be 
incredibly useful for the data-gathering aspect of the project.
