问题
is it possible to detect a speed of a car using GPS or accelerometer in android phone ?
can anyone give me the road map to implement this ?

Yes, it's possible using GPS via object of Location class. There is getSpeed() method in this class.
It's very easy to find code of getting location. Check this link for example.
